Dextrose. Fructose. Lactose. Maltose. Glucose. A sugar by any other name is still sugar. In fact, there are more than 50 different names for it. But is sugar bad for you? Essentially, there are two types of sugar; there is “good” sugar that occurs naturally in fruits and vegetables and “bad” added sugar that’s added to sweeten sodas, candy, baked goods, and so on.
The “good” sugar is actually needed within the body, particularly within the brain. Following a meal, food is broken down; specifically glycogen, carbohydrates, proteins, fats and triglycerides, which are broken down into glucose. Glucose is so crucial to cell function that glucose deprivation can lead to loss of consciousness and eventual cell death. Therefore, after a meal, the body has a system in place in which excess glucose is stored as a reserve.
All cells need the energy to function; the large mass of neuron cells that make up the brain needs energy, largely in the form of glucose, to function. Did you know that the brain uses approximately 20 percent of an individual’s daily energy intake? (1)
Not only is sugar essential for your basic brain functions, but it tastes delicious too! Once you eat something with sugar in it, your taste receptors are activated, sending signals to your brain that set off an entire cascade of stimulation. In particular, the dopaminergic pathway is activated and triggers your “YUM!” signal. This pathway starts in a cluster of cells at the base of your brainstem called the ventral tegmental area (VTA) and extends through the lateral hypothalamus to the nucleus accumbens in the forebrain. Behaviors that stimulate the release of the neurotransmitter, dopamine, within this pathway have been shown to be highly motivational.
Glucose is crucial to cell function and survival and it stimulates the reward pathway in your brain which makes everything feel like unicorns and rainbows. Life is good. Except that too much of something, is usually the opposite of good. But how many grams of sugar should you ingest per day? The American Heart Association suggests that individuals ingest a maximum daily intake of 6 teaspoons of sugar for women and 9 teaspoons for men. On average, people ingest 22 teaspoons of added sugar, which is on top of the naturally occurring sugar in our diet. (2, 3)
So as our reward pathway keeps getting stimulated, the dopamine receptors become desensitized and require more dopamine to get the same pleasant feeling.
Therefore, there needs to be more consumption of, in this case, the sugary food or beverage, to elicit the same response. This increase in consumption has been shown to result in obesity, including childhood obesity. An increased diet in saturated fats and sugar (also known as a high-energy diet) can have fundamental changes within the brain that in conjunction with the increased neurotransmitter release (dopamine) can have detrimental effects. Such effects include…
Learning and Memory
Studies show that a diet high in sugar and saturated fats can promote oxidative stress, leading to cell damage. In 2010 Scott Kanoski, an associate professor of biological sciences at Perdue University, demonstrated that a three-day diet of increased sugar and saturated fats resulted in impaired hippocampal function (learning and memory), causing the rats to have difficulty finding food within a maze. (4)
Other studies also illustrate that the hippocampus, in particular, is sensitive to a high-energy diet. (5)
Addiction
Sugar addiction is real. The pathway activated for addiction is the same as the reward pathway. Persistent increases in the release of the neurotransmitter, dopamine, leads to desensitization and requires more consumption for the reward. It changes gene expression and creates a consumption→ Dopamine release→ reward→ pleasure→ motivate cycle that is increasingly difficult to break. (6)
Depression & Anxiety
Attempts in trying to break the addictive cycle can lead to mood swings and irritability. Eliminating all additive sugar from your diet can lead to some of the same symptoms of drug withdrawal. Sugar withdrawal symptoms include headaches, anxiety, cravings and even chills.
Cognitive Deficits
Prolonged diets with high sugar may lead to changes in gene expression. That affects everything from neurotransmitters to receptors and the basic function of the cell. In particular, studies suggest the brain-derived neurotrophic factor (BDNF) is impacted. This is active in the hippocampus, cortex and forebrain and is vital to learning and memory, as well as supporting existing neurons while promoting the formation of new synapses. This is reduced in high sugar diets. (7)
Therefore, it’s unsurprising that a correlation between low BDNF levels and Alzheimer’s, depression and dementia has been discovered. New and continuing research in the field of neuroscience continues to provide valuable information on the effect that excessive sugar has on the brain. Further information gained from such research could also lead to changes in the way that specific cognitive disorders are treated. (8)

NIH study in rats suggests that support cells modulate brain circuit activity.
A fresh look at the brain and breathing: NIH study in rats shows that star-shaped brain cells, called astrocytes (red) may play an active role in breathing. Jeffrey C. Smith lab, NIH/NINDSTraditionally, scientists thought that star-shaped brain cells called astrocytes were steady, quiet supporters of their talkative, wire-like neighbors, called neurons. Now, an NIH study suggests that astrocytes may also have their say. It showed that silencing astrocytes in the brain’s breathing center caused rats to breathe at a lower rate and tire out on a treadmill earlier than normal. These were just two examples of changes in breathing caused by manipulating the way astrocytes communicate with neighboring cells.
“For decades we thought that breathing was exclusively controlled by neurons in the brain. Our results suggest that astrocytes actively help control the rhythm of breathing,” said Jeffrey C. Smith, Ph.D., senior investigator at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) and a senior author of the study published in Nature Communications. “These results add to the growing body of evidence that is changing the way we think about astrocytes and how the brain works.”
Dr. Smith’s lab investigates how breathing is controlled by the rhythmic firing of neurons in the preBötzinger complex, the brain’s breathing center that his lab helped discover. For this study, his team worked with Alexander Gourine, Ph.D., professor at University College London (UCL), whose lab found that astrocytes in neighboring parts of the brain may regulate breathing by sensing changes in blood carbon dioxide levels.
At least half of the brain is comprised of cells called glia and most of them are astrocytes. Recently scientists have shown that astrocytes may communicate like neurons by shooting off, or releasing, chemical messages, called transmitters, to neighboring cells.
In this study, the scientists tested the role of astrocytes in breathing by genetically modifying the ability of astrocytes in the preBötzinger complex to release transmitters. When they hushed the astrocytes in rats by reducing transmitter release, the rats breathed and sighed at a lower rate than normal. In contrast, if they made the astrocytes chattier by increasing transmission, the rats breathed at higher resting rates and sighed more often.
The team also tested how silencing astrocytes affected the rats’ responses to changes in oxygen and carbon dioxide levels. Although the rats’ breathing rate increased when oxygen levels were lower or carbon dioxide levels higher, it was still lower than normal. Silencing astrocytes also decreased the rate at which the rats sighed under lower oxygen levels. Moreover, the rats became exhausted much earlier than normal. They could only run half the distance that normal rats could run on a treadmill before tiring out.
“The primary goal of breathing is the exchange of carbon dioxide and oxygen that is critical for life. Our results support the idea that astrocytes help the brain translate changes in these gases into breathing,” said Shahriar Sheikhbahaei, Ph.D., formerly a doctoral student at UCL and participant in the NIH Graduate Partnership Program, and the lead author of the study.
Finally, the team showed that these astrocytes used adenosine triphosphate (ATP) to communicate with other cells in the brain. Inactivating released ATP reduced resting breathing rates and the frequency of sighs under normal and low oxygen levels.
“Our results expand our understanding of how the brain controls breathing under normal and disease conditions,” said Dr. Smith. “We plan to follow this path to understand how astrocytes help control other aspects of breathing.”
This study was supported by the Intramural Research Program at the NINDS, the Wellcome Trust, British Heart Foundation (Ref. RG/14/4/30736), BBSRC (Refs. BB/L019396/1, BB/K009192/1), the Medical Research Council (Ref. MR/L020661).

Prescription painkillers “are not a panacea,” said Dr. Lynn Webster of the American Academy of Pain Medicine. “But some patients respond very well and we need to have these medications available.” Photo Credit: Newsday/Audrey C. Tiernan
“We’ve gotten too used to popping pills in this country,” said Dr. Andrew Kolodny, chief of psychiatry at Maimonides Medical Center in Brooklyn. “There are other ways to deal with pain.”
But doctors who treat chronic-pain patients contend the drugs are vital to managing intractable pain.”These medications are very helpful for a subset of chronic-pain patients,” said Dr. Lynn Webster of the American Academy of Pain Medicine. “They are not a panacea. But some patients respond very well and we need to have these medications available.”
In the United States, about one in every 20 people age 12 and older — 12 million people — say they’ve used prescription painkillers nonmedically, according to the National Survey on Drug Use and Health.
The Centers for Disease Control and Prevention estimates 5,500 people start prescription painkiller abuse every day in this country. The agency also estimates 40 people die daily nationwide of prescription drug overdoses.
Kolodny, president of Physicians for Responsible Opioid Prescribing, traces the problem to unprecedented amounts of prescription narcotics in the pharmaceutical supply chain.
The International Narcotics Control Board, a division of the United Nations, estimates global pharmaceutical companies produce more than 75 tons a year of oxycodone, compared with 11.5 tons in 1999. More than 80 percent of the worldwide oxycodone supply is consumed in the United States, according to board estimates.
Kolodny contends there’s no reason Americans should consume most of the world’s oxycodone as well as the lion’s share of many other major narcotic medications.
Hydrocodone is the most widely prescribed drug in the United States, according to the CDC. In December, the international narcotics board estimated U.S. demand for hydrocodone to be about 27.4 million grams annually compared with 3,237 grams for Britain, France, Germany and Italy combined. A typical dose is about 5 milligrams.
Doctors who treat patients in pain, meanwhile, are concerned pressure is mounting against narcotic medications.
Webster said critics too often overstate the degree to which people are addicted.
“I am not sure I would use the word epidemic,” he said. “There is a public health crisis, but not an epidemic.”
Webster criticized the CDC, which declared an epidemic of pain-pill abuse, saying patients prescribed narcotic pain pills need them.
Yet, prescription painkillers can be as addictive as their chemical cousin heroin — and they are purer because they’re made in world-class labs, experts say.
“These drugs are very, very active in the brain,” said Dr. Stephen Dewey, director of behavioral and molecular neuroimaging at the Feinstein Institute for Medical Research in Manhasset.
Dewey uses sophisticated imaging technology to trace the destructive path drug abuse causes in the brain. He has found that narcotics of all kind can damage vast populations of cells and alter human behavior as a consequence.
“As a rule of thumb, if you’re in pain the addictive liability of these drugs is very low,” Dewey said. “But more and more people are taking them in the absence of pain when their addictive liability is very high. And because of that, they get hooked very quickly.”
Hydrocodone, oxycodone and oxymorphone are the key prescription drugs of abuse, data from the CDC show.
Taken as an intact pill, any of the drugs can extinguish pain when dispersed in micro-quantities over several hours.
Once pulverized into a fine powder and sniffed; crushed to destroy time-release features and ingested; or, liquefied and injected, they become black-market commodities that act within minutes.
Physical dependence can occur rapidly — within days — when the pill casing is broken, Dewey said. Weight, age and genetics, he added, govern how fast full-blown addiction occurs, and teen users are highly vulnerable to addiction.
All narcotic medications are members of the opioid drug class, Dewey said.
When abused, prescription-grade narcotics produce the same effect as heroin and are converted into morphine in the brain.
The morphine flood switches on key proteins — opiate receptors — which modulate the body’s pleasure and reward system, Dewey said. Thousands of the receptors pervade the brain, spinal cord, intestines and respiratory system.
The drugs also trigger a copious flow of dopamine, causing the hallmark rush of euphoria, another characteristic of heroin addiction.
Dr. Rita Goldstein, a neuroscientist at Brookhaven National Laboratory, noted virtually all misused narcotics become addictive because of the body’s unbridled cravings for euphoria.
“All of the drugs of abuse increase the release of dopamine,” Goldstein said. “So the more of the drug you take, the more of a dopamine response you get, and the more dopamine, the greater the high.”
Dewey said as addiction takes hold, opioid drugs begin altering cells in the brain’s orbital frontal cortex, the region “that makes us think before we act.”
The inability to perceive danger, to recognize a need for sustenance over drug consumption, and to act responsibly typify opioid addiction, he said.
In Suffolk County, District Attorney Thomas Spota said his office has seen a surge in fatal car accidents and criminal activity related to prescription drug abuse.
Dr. Rick Terenzi, chief of North Shore University Hospital‘s drug treatment and education center, said more than half the children and teens he has counseled for prescription painkiller use report getting the drugs from home, usually from the family medicine cabinet.
“When you look at the number of pain relievers that are prescribed or available,” Terenzi said, “and the number of people who have access to pharmaceutically pure opioids, then you start getting an idea about the scope of this problem.”
The US ‘War on Drugs’ has had a profound role in reinforcing racial hierarchies. Although Black Americans are no more likely than Whites to use illicit drugs, they are 6–10 times more likely to be incarcerated for drug offenses. Meanwhile, a very different system for responding to the drug use of Whites has emerged. This article uses the recent history of White opioids – the synthetic opiates such as OxyContin® that gained notoriety starting in the 1990s in connection with epidemic prescription medication abuse among White, suburban and rural Americans and Suboxone® that came on the market as an addiction treatment in the 2000s – to show how American drug policy is racialized, using the lesser known lens of decriminalized White drugs. Examining four ‘technologies of whiteness’ (neuroscience, pharmaceutical technology, legislative innovation and marketing), we trace a separate system for categorizing and disciplining drug use among Whites. This less examined ‘White drug war’ has carved out a less punitive, clinical realm for Whites where their drug use is decriminalized, treated primarily as a biomedical disease, and where their whiteness is preserved, leaving intact more punitive systems that govern the drug use of people of color.
The US ‘War on Drugs’ has had a profound role in reinforcing racial hierarchies. Drug offenses accounted for two-thirds of the rise in the federal inmate population and more than half of the rise in state prisoners between 1985 and 2000, with more than half of young Black men in large cities in the United States currently under the control of the criminal justice system (Alexander, 2010), and middle aged Black men more likely to have been in prison than in college or the military (Rich et al, 2011). Although Black Americans are no more likely than Whites to use illicit drugs, they are 6–10 times more likely to be incarcerated for drug offenses (Bigg, 2007; Goode, 2013). Alexander (2010), Wacquant (2009), Hart (2013) and others make the case that the criminal justice system is, in effect, a new state-sponsored racial caste system.
Meanwhile, a very different system for responding to the drug use of Whites has emerged. Beginning in the 1990s, rates of prescription opioid misuse – primarily OxyContin® – began to rise dramatically, particularly among Whites. The press reported a suburban and rural White prescription opioid epidemic (Tough, 2001; Ung, 2001a, b) as prescription drug overdose deaths rose 117 per cent between 1999 and 2012 (CDC, 2014). By 2010, the National Institute on Drug Abuse (NIDA) noted increasing numbers of prescription opioid dependent people turning to heroin as prescription opioids became harder to misuse (Volkow, 2014) because of new prescription monitoring programs and tamper resistant opioid formulations. Thousands of White addicted people found themselves the center of media and political debates about how the country should respond to the latest drug crisis.
The public response to White opioids looked markedly different from the response to illicit drug use in inner city Black and Brown neighborhoods, with policy differentials analogous to the gap between legal penalties for crack as opposed to powder cocaine. This less examined ‘White drug war’ has carved out a less punitive, clinical realm for Whites where their drug use is decriminalized, treated primarily as a biomedical disease, and where White social privilege is preserved. This ‘White drug war’ has historical precedents in which predominantly White populations have used social privilege to invoke ‘medical need’ to secure or maintain access to powerful sedatives or stimulants in the mid to late twentieth century (see Herzberg, 2013). But in the case opioids, addiction treatment itself is being selectively pharmaceuticalized in ways that preserve a protected space for White opioid users, while leaving intact a punitive, carceral system as the appropriate response for Black and Brown drug use.
Whiteness is a sociocultural achievement: it is actively maintained through the shoring up of social boundaries distinguishing White and from not White (Frankenberg, 1993; Allen, 1994; Fine et al, 1996; Daniels, 1997; Wray, 2006; Roediger, 2007; Twine and Gallagher, 2008; Hughey, 2010). The seeming inevitability and naturalness of whiteness allows those within the category ‘White’ to be unmarked, to think of themselves as simply human and without race, while those who fall outside the bounds of whiteness are the racialized Other (Dyer, 1988). Scholars have explored the ways in which whiteness shapes housing (Low, 2009), education (Leonardo, 2009), politics (Feagin, 2012), law (Lopez, 2006), research methods (Zuberi and Bonilla-Silva, 2008) and our understanding of society (Lipsitz, 2006 [1998]; Feagin, 2010). Yet, despite almost two decades of research in the field of whiteness studies, there remains relatively little literature that explores the myriad connections between whiteness and health in the US context (Katz Rothman, 2001; Daniels and Schulz, 2006; Jones, et al, 2008; Daniels, 2012; Daniels, 2013) and only a few studies exploring the issue of whiteness and psychoactive substances (Steiner and Argothy, 2001; Murakawa, 2011; Daniels, 2012; Linnemann and Wall, 2013).
In one of the only studies to explicitly look at how drug policy is used to carve out White spaces exempt from punitive more approaches, Lassiter (2015) takes a historical look at the roots of the White opioid crisis of today. Looking back to marijuana policies of the 1970s, he states: “exemptions created for white middle-class participants in the underground market-place were not merely epiphenomenal but rather constitutive of the expansion of the carceral state (p. 127)”. The drug war operates because of a reciprocal relationship between the criminalization of blackness and the decriminalization of whiteness. Lassiter notes that, when the Rockefeller Drug Laws instituted harsh mandatory minimums, White suburban youth found themselves facing significant jail time for low-level marijuana possession. Parents of White suburban youth banded together to create policy changes that exempted marijuana from the Rockefeller Drug Laws, essentially decriminalizing low-level possession in some jurisdictions. This was possible, in part, because of the racial dynamics and the portrayal of White youth as sympathetic victims of the organized narcotics trade. The relative paucity of studies, such as Lassiter’s examining the constitutive role of whiteness in the drug war, is remarkable given the wealth of sociocultural research on pharmaceuticals, addiction and race, which has illuminated myriad ways that the biochemical stratification of people of African and Latin American origin has been represented and materially shaped in sites ranging from genetics labs, medical clinics and neighborhoods, to popular media, courtrooms and policy debates (c.f. Campbell, 2000; Courtwright, 2001; Fullwiley, 2007; Singer, 2008; Bourgois and Schonberg, 2009; Roberts, 2011; Tiger, 2012).
While not focused on addiction, some scholars have traced the ways that medicine has always been racialized and used to justify less punitive responses for Whites than Blacks. For example, Solinger (2013)traces how a racial divide was produced and maintained by the discourses surrounding “illegitimate” childbirth and the medicalization of abortion. While abortion became available and somewhat acceptable for Whites, the welfare system was being used to publicly shame and punish women of color who had children out of wedlock. Other studies trace how race became embedded in medical technologies and rhetoric in ways that become taken for granted and that reinforce notions of racial difference. Pollock (2012), in a study of the racialization of heart disease, notes that whiteness is reinforced by its using the famous Framingham study as the norm. Braun (2014) traces the ways that the spirometer, originally developed in the antebellum South to demonstrate the physiological inferiority of Black slaves, continues to naturalize racial difference in contemporary usage through “race correction” of “normal” reference ranges. These works remind us that racial projects are inherently implicated in medicine and that race is reified in discourses of legitimacy, normativity and technological precision.
White race is encoded into biomedical technologies and practice in particularly covert, implicit rather than explicit ways and in ways that may not be intentional on the part of key actors. Our argument here focuses on racializing consequences of pharmaceutical reason that stem from pre-existing structures of exclusion, inclusion, political pragmatism and industry that over-determine the strategies of scientists, treatment advocates, policymakers and pharmaceutical executives. Opioids in the United States are subjected to a racial biopolitics that constrains available strategies, even to those who oppose social hierarchies and strive to de-racialize drug policy. Efforts to de-racialize any arena of life in the United States, which do not directly address racism, risk reproducing racial hierarchy, because White privilege is typically reproduced by eliminating racial references from seemingly universal policies and practice; in the latter part of the twentieth century the social policy reforms that did the most to intensified racial inequalities in income, employment and incarceration were undertaken under the guise of “color blind ideology” (Alexander, 2010).
This article uses the recent history of White opioids – the synthetic opiates OxyContin® and Suboxone®that gained notoriety starting in the 1990s in connection with epidemic prescription medication abuse among White, suburban and rural Americans – to show how American drug policy is racialized, using the lesser known lens of decriminalized White drugs. Examining four ‘technologies of whiteness’ (neuroscience, pharmaceutical technology, legislative innovation and marketing), we trace a separate system that categorizes and disciplines drug use among Whites, while not naming White race explicitly, given that White is the unmarked, assumed norm. Maintaining the boundaries of whiteness under racially segregated drug policy requires constant vigilance and ongoing political work. Our thesis is that these technologies of whiteness are fueled by two biopolitical currents that trade on hidden or misrecognized racial coding: on one hand, a partnership of the pharmaceutical industry with lawmakers who are conscious of the racial symbolism of addiction risk and legitimate use of opioids, and on the other, an unconscious collusion of liberal neuroscientists seeking to decriminalize opioid misuse and democratize treatment using a discourse of addiction as a brain disease, while failing to recognize the (White) racial coding in the universal brain disease framework and its disparate consequences.
The mass incarceration of people of color for drug offenses is, in part, legitimated by the belief that drug use results from a failure of will or morality. People are responsible for their use and, therefore, must be held accountable or punished. However, at the same time that more punitive War on Drug policies were enforced in Black and Latino city neighborhoods, President Bush I ushered in the Decade of the Brain at the National Institute on Drug Abuse. The richly funded neuroscience program at NIDA in the 1990’s provided a scientific rationale for addiction as a clinical disease, focusing on altered brain chemistry as the source of addiction and on neuroactive pharmaceuticals and clinical (rather than law enforcement) interventions as the appropriate response. Simply put, neuroscience provided a scientific rationale for treating addictions – at least some addictions – as disease needing medical intervention rather than as crime requiring punishment. While the race of the addict was excluded from this universalizing biological discourse, the very absence of a language of race indexed White subjects. The scientists involved in this project probably did not intend to exacerbate racial inequalities with their work; on the contrary, many saw their efforts to establish the neurochemical basis for addiction as a way to counteract the social injustice of addiction stigma, and, by extension, racial injustice. Yet, the implicit racial logic of universalist clinical research, which has long held the 70 kg White male as its standard subject (Epstein, 2007), channeled the efforts of even egalitarian neuroscientists toward stratified results.
In the United States, NIDA spent millions of dollars promoting one simple message: ‘addiction is a brain disease’. In 1997, Alan Leshner, then Director of NIDA, published a landmark article entitled, “Addiction is a Brain Disease, and It Matters”. In the article, Leshner argues that addiction is as much a medical as a social problem and that the field and the public has focused too much attention on the latter:
That addiction is tied to changes in brain structure and function is what makes it, fundamentally, a brain disease. … Understanding that addiction is, at its core, a consequence of fundamental changes in brain function means that a major goal of treatment must be to either reverse or compensate for those brain changes.
(1997, p. 46)
It is this perspective that has guided NIDA since. It has also permeated the field of addictions research through the 1990s, as demonstrated by a landmark article in the Journal of the American Medical Association, co-authored by four prominent addictions researchers, and entitled “Drug Dependence, A Chronic Medical Illness”. The article argued that drug dependence was comparable to asthma, diabetes and hypertension in terms of heritability, causation, pathophysiology and adherence to treatment, and that it should be treated as a chronic medical illness for purposes of treatment approaches, insurance coverage and outcome measures (McLellan et al, 2000). In 2003, Nora Volkow, a prominent neuroscientist who pioneered the use of PET scans in addiction research, became the Director of NIDA. Since her appointment, she has vociferously championed the brain disease model in both NIDAs scientific and public education arms. For example, in 2005 NIDA underwrote a widely-cited issue of Nature devoted to addiction neurobiology. NIDA has also produced a series of curricula for elementary and high school students to explain addiction. These include: “Brain Power”, “Mind Over Matters”, “Heads Up” and “The Brain”. NIDAs educational materials closely track the scientific literature. NIDAs power in the field of addiction neuroscience has led one scholar to describe them as largely responsible for making “the neuroscientists’ laboratory … an obligatory passage point for the production of truths about addiction” (Vrecko, 2010, p. 58).
Addiction neuroscience is connected to whiteness and addiction is three key ways. First, whiteness and health are implicated in the use of brain imagery. Images, such as PET scans, of the ‘addicted brain’ are increasingly popular in addiction studies and in reporting on addiction. While images of drug-related brain damage or craving-induced brain activity are compelling and are liberally used in NIDAs educational materials, several scholars have noted that imaging technologies, far from being objective or neutral, are shaped by their social and economic context and involve a series of subjective decisions by researchers (see especially, Beaulieu, 2001; Dumit, 2004; Joyce, 2005). What is striking about brain images of addiction is that they are unmarked by race: they convey a sense of universality and timelessness that, by omitting racial identity, help to expunge racial identity of the addict leaving a White, because racially unmarked, backdrop. Brain scans here operate as the unmarked White norm similar to the way in which the Framingham study of predominantly White participants became the norm for heart disease (Pollock, 2012). A neuroscientific model of addiction as brain disease, which extracts the brain from the racially marked addicted body, thereby helps to unmark (biological) addiction, defining it as a human universal, and therefore White. The neuroscientific reframing of addiction is, therefore, a technique for the racial recoding of (certain types of) addiction and of (some) addicted people, which extracts addiction from the association with Black and Latino people inherent in a social, moral, or criminal framing of addiction.
Neuroscience and whiteness are further connected through the silence in neuroscientific literature about the role of environmental factors contributing to addiction. Social determinants of health, such as geography, income, education and housing are largely omitted from the description of research subjects and from the lists of relevant variables in neuroscientific papers. Environmental factors in addiction neuroscience are generally reduced to cues or triggers (for example, studies demonstrating how brain ‘lights up’ when a drug user is shown a picture of heroin or cocaine). Even when environmental forces are acknowledged, they are of interest primarily for the biochemical processes they engender. Volkow and Li explain the “neural consequences of environmental risk”:
Low socioeconomic class and poor parental support are two other factors [along with drug availability] that are consistently associated with a propensity to self-administer drugs, and stress might be a common feature of these environmental factors […T]here is evidence that corticotropin-releasing factor (CRF) might play a linking role through its effects on the mesocorticolimbic dopamine system and the hypothalamic pituitary-adrenal axis. […] If we understand the neurobiological consequences underlying the adverse environmental factors that increase the risk for drug use and addiction, we will be able to develop interventions to counteract these changes.
(2005, p. 1436)
Here, environmental influences are acknowledged but understood only in the context of how the stress they induce affects the dopamine system. Volkow and Li (2005) go on to suggest that the future addiction interventions may include medications that act synergistically with behavioral therapies to mitigate the impact of stress. Absent from their view of addiction are features of neighborhood environment or social roles that might hint at the context of drug use, and therefore the race of drug users and their stressors. They offer an individually focused clinical and physiological, rather than a public health, model of addiction.
The third connection between addiction neuroscience and whiteness is what neuroscience frames as the appropriate response to addiction. When addiction is conceptualized as a ‘brain disease’ involving genetically and physiologically determined neuroreceptors, what is called for is a medication that specifically targets faulty neuroreceptors. This stands in stark contrast to the prevalent response to addiction in the United States as part of the War on Drugs in which incarceration is the ready response. When addiction is framed as a brain disorder, rather than a crime, its cultural work to racially recode prescription opioid addiction as White is unrecognized. This ultimately leads to a bifurcated discourse of White addicts as having a ‘brain disease’ and needing ‘treatment’, and of non-White addicts as ‘criminals’ that require incarceration to protect the public.
It seems, however, that some neuroscientists are unaware of the role their work is playing in reinscribing racialized notions about drug users. Indeed, some addiction neuroscience researchers have said that their political project was to delink addiction from crime. They see themselves as reframing addiction as a brain disease for the precise purpose of destigmatizing and decriminalizing drug use and bringing it under the purview of medicine, rather than the criminal justice system. Dackis and O’Brien, for instance, claim that neuroimaging will:
substantiate the biological basis of addiction and […] ultimately erode entrenched societal attitudes that prevent addiction from being evaluated, treated, and insured as a medical disorder.
(2005, p. 1431)
Such researchers believe that promoting a neurological basis for addiction will erode the persistent idea that addiction is “a character flaw rather than a bona fide brain disease” (Chou and Narasimhan, 2005, p. 1427), leading to the end of stigma and criminalization. Importantly, both models – the moral/criminal and the medical – root the etiology of addiction at the level of the individual, absenting from consideration structural and environmental factors.
These discussions do not explicitly reference race, but it is notable that the neurobiological, universal, by extension ‘White’ and therefore less stigmatizing and criminalizing concept of addiction, was aggressively developed during a decade (the 1990s) when middle class, White heroin use was growing. This change in the demographics of heroin consumption was because of an influx of heroin from newly planted poppy fields in Colombia, whose cartels were competing with established Middle Eastern and Asian heroin distributors by dramatically lowering the price and increasing the purity of the heroin they sold in the United States cities. This attracted middle class users who found they could snort instead of injecting the purer heroin (Hamid et al, 1997). In addition, with the 1996 approval of OxyContin® as a “minimally addictive pain reliever” marketed to generalist physicians in rural and suburban areas for their use in moderate pain (Van Zee, 2009), by the late 1990s the specter of the coming White prescription opioid addiction epidemic had been raised.
By focusing on brain neurochemistry, the neuroscientific model of addiction, referred to by many neurophysiology researchers as ‘chronic relapsing brain disease’, erases and obscures the role of race and other social differences in ways that privilege whiteness. The brain disease model of addiction reduces any discussion about poverty, exposure to drugs, racism and other environmental factors to problems of the brain and its response to ‘stress’. Social issues, such as the mass incarceration of African Americans under harsh drug laws or the lack of viable economic opportunities beyond the drug trade in Black and Latino neighborhoods, have no place in neuroscientific discourse. As Nancy Campbell notes, “as an ideological code, CRBD [chronic relapsing brain disease] does not focus attention on social differences, including the differential histories and cultural geographies within which their subjects encounter drugs” (2010, p. 101).
As we discuss further below, this neuroscientific racial recoding of prescription opioid addiction was one basis for legislative innovations that created a new, separate track for treating the addiction of White opioid users.
Opioids have long blurred the line between legitimate medications and drugs of abuse. Morphine went into widespread use during the Civil War in the treatment of injured soldiers, and among middle class White Victorian housewives for a range of problems including menstrual pain. Morphine ‘habits’ only began to be seen as problematic at the end of the nineteenth century; in 1898 Bayer Corporation introduced heroin as a non-addictive cure for morphine addiction as well as a cough syrup for children. However, changes in medical practice and international drug policy led the media and policymakers to associate opiates with poverty and ethnic minorities, and prohibitionists succeeded in banning opiate maintenance from clinical practice with passage of the 1914 Harrison Act (Musto, 1999; Courtwright, 2001). Methadone was introduced as a synthetic opioid pain reliever in Germany during World War II when morphine supplies from Asia ran short, was re-introduced in the 1960s as a maintenance medication for heroin addiction following successful clinical trials among African Americans in Harlem (Dole and Nyswander, 1966), and was named a primary weapon in President Nixon’s War on Drugs in 1971 (White, 1998). Methadone quickly become the focus of tight surveillance and regulation by the DEA, however, based on reports of methadone abuse and diversion, and on methadone’s symbolic association with Black and Brown inner city drug use (Hansen and Roberts, 2012). New opioids have therefore undergone a predictable cycle of optimism touted as the holy grail of a non-addictive pain reliever, followed by challenges to their legitimacy as medications, their association with poverty and ethnic minorities, and stigmatization as addictive drugs.
Oxycodone is a semisynthetic opioid synthesized from thebaine, an opioid alkaloid found in the Persian poppy, and one of the many alkaloids found in the opium poppy. It is a moderately potent opioid pain medication (orally roughly 1.5 times more potent than morphine),[8] generally indicated for relief of moderate to severe pain.[9] Oxycodone was developed in 1917 in Germany[10][11] as one of several semi-synthetic opioids in an attempt to improve on the existing opioids.[1]
Oxycodone is available as single-ingredient medication in immediate release and controlled release. In the United Kingdom, it is available in 10 mg/mL and 50 mg/mL formulation for intramuscular or intravenous administration.[12]Combination products are also available as immediate-release formulations, with non-narcotic analgesic ingredients such as paracetamol (acetaminophen) and nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin and ibuprofen.
As it has euphoric effects similar to other opioids, oxycodone is one of the drugs abused in the current opioid epidemic in the United States.[13][14] An abuse-deterrent combination with naloxone is available in managed-release tablets. If injected, the naloxone precipitates opioid withdrawal symptoms and blocks the effect of the medication. However, there have been concerns raised about the effectiveness of the abuse prevention measures.[14][15]
Oxycodone has been in clinical use since 1916,[1] and it is used for managing moderate to moderately severe acute or chronic pain.[16] It has been found to improve quality of life for those with many types of pain.[17] Experts are divided regarding use for non-cancer-related chronic pain, as most opioids have great potential for dependence and have also been alleged to create paradoxical pain sensitivity.
Oxycodone is available as controlled-release tablet, intended to be taken every 12 hours.[18] A 2006 review found that controlled-release oxycodone is comparable to instant-release oxycodone, morphine, and hydromorphone in management of moderate to severe cancer pain, with fewer side effects than morphine. The author concluded that the controlled release form is a valid alternative to morphine and a first-line treatment for cancer pain.[19] In 2014, the European Association for Palliative Care recommended oral oxycodone as a second-line alternative to oral morphine for cancer pain.[20]
In the U.S., extended-release oxycodone is approved for use in children as young as 11 years old. The approved indication is for relief of cancer pain, trauma pain, or pain due to major surgery, in children already treated with opioids, who can tolerate at least 20 mg per day of oxycodone; this provides an alternative to Duragesic (fentanyl) the only other extended-release opioid analgesic approved for children.[21]
In the United States, oxycodone is only approved for oral use, available as tablets and oral solutions. In Spain, the Netherlands and the United Kingdom, oxycodone is also approved for intravenous (IV) and intramuscular (IM) use. When first introduced in Germany during World War I, both IV and IM administrations of oxycodone were commonly used for postoperative pain management of Central Powers soldiers.[1]
Main side effects of oxycodone[22]
Serious side effects of oxycodone include reduced sensitivity to pain (beyond the pain the drug is taken to reduce), euphoria, anxiolysis, feelings of relaxation, and respiratory depression.[23] Common side effects of oxycodone include constipation (23%), nausea (23%), vomiting (12%), somnolence (23%), dizziness (13%), itching (13%), dry mouth (6%), and sweating (5%).[23][24] Less common side effects (experienced by less than 5% of patients) include loss of appetite, nervousness, abdominal pain, diarrhea, urine retention, dyspnea, and hiccups.[25]
In high doses, overdoses, or in some persons not tolerant to opioids, oxycodone can cause shallow breathing, slowed heart rate, cold/clammy skin, pauses in breathing, low blood pressure, constricted pupils, circulatory collapse, respiratory arrest, and death.[25]
Oxycodone overdose has also been described to cause spinal cord infarction in high doses and ischemic damage to the brain, due to prolonged hypoxia from suppressed breathing.[26]
Oxycodone in combination with naloxone in managed-release tablets, has been formulated to both deter abuse and reduce “opioid-induced constipation”.[27]
The risk of experiencing severe withdrawal symptoms is high if a patient has become physically dependent and discontinues oxycodone abruptly. Medically, when the drug has been taken regularly over an extended period, it is withdrawn gradually rather than abruptly. People who regularly use oxycodone recreationally or at higher than prescribed doses are at even higher risk of severe withdrawal symptoms. The symptoms of oxycodone withdrawal, as with other opioids, may include “anxiety, panic attack, nausea, insomnia, muscle pain, muscle weakness, fevers, and other flu-like symptoms“.[28]
Withdrawal symptoms have also been reported in newborns whose mothers had been either injecting or orally taking oxycodone during pregnancy.[29]
As with other opioids, chronic use of oxycodone (particularly with higher doses) often causes concurrent hypogonadism or hormone imbalance.[30]
Oxycodone is metabolized by the enzymes CYP3A4 and CYP2D6, and its clearance therefore can be altered by inhibitors and inducers of these enzymes.[31] (For lists of CYP3A4 and CYP2D6 inhibitors and inducers, see here and here, respectively.) Natural genetic variation in these enzymes can also influence the clearance of oxycodone, which may be related to the wide inter-individual variability in its half-life and potency.[31]
Ritonavir or lopinavir/ritonavir greatly increase plasma concentrations of oxycodone in healthy human volunteers due to inhibition of CYP3A4 and CYP2D6.[32]Rifampicin greatly reduces plasma concentrations of oxycodone due to strong induction of CYP3A4.[33] There is also a case report of fosphenytoin, a CYP3A4 inducer, dramatically reducing the analgesic effects of oxycodone in a chronic pain patient.[34] Dosage or medication adjustments may be necessary in each case.
