Glamorization Of Drugs In Rap Music Linked To Greater Risk Of Alcohol And Drug Use Among Adolescents

A new study finds that references to illegal drug use in rap music jumped sixfold in the two decades since 1979, the year Sugar Hill Gang's "Rapper's Delight" hit the charts and introduced to a mainstream audience a music genre born from inner-city America.



Moreover, illegal drug use became increasingly linked during this time period to wealth, glamour and social standing, marking a significant change from earlier years, when rap music was more likely to have depicted the dangers and negative consequences of drug abuse, according to the study authored by Denise Herd, associate professor in the division of Community Health and Human Development at the University of California, Berkeley's School of Public Health.



"This trajectory in rap music raises a number of red flags," said Herd, who also is associate dean for student affairs at the School of Public Health. "Rap music is especially appealing to young people, many of whom look up to rappers as role models. As a public health researcher, and as a parent of a 7-year-old, I'm concerned about the impact that long-term exposure to this music has on its listeners."



The new study, published in the April issue of the peer-reviewed journal Addiction Research & Theory, is the first scientific survey to analyze the content of rap music over two decades.



Herd and her team examined the lyrics of 341 of the most popular rap songs - as determined by Billboard and Gavin music rating services - from 1979 to 1997. Researchers coded songs for drug mentions, behaviors and contexts surrounding the mention of drugs, as well as the attitudes and consequences stemming from illicit drug use.



Of the 38 most popular rap songs between 1979 and 1984, only four, or 11 percent, contained drug references. In the early 1990s, the percentage of rap songs with drug references experienced a sharp jump to 45 percent, and steadily increased to 69 percent of the 125 top rap songs between 1994 and 1997.



The study found that drug references in early rap songs - "White Lines" by Grandmaster Flash, "Crack Monster" by Kool Moe Dee and "Night of the Living Baseheads" by Public Enemy - often depicted the destructiveness of cocaine and, particularly, of crack, its freebase form.



This cautionary tone about cocaine gave way to rap lyrics in the early 1990s that increasingly portrayed marijuana use as a positive activity. The UC Berkeley study documented a threefold increase between 1979 and 1997 in rap songs' mentions of marijuana and marijuana-stuffed cigars, or "blunts," and noted marijuana's association in those songs with creativity, wealth and status.



Herd noted that the study puts hard numbers to a trend that has long been noted anecdotally among observers of the music industry. She referenced a 1996 article in Vibe, a magazine that covers hip hop culture, highlighting the success of Cypress Hill's 1991 debut album celebrating marijuana use as a turning point in rap music's popularization of the drug. The Vibe article noted that other rap artists, including Dr. Dre and Snoop Dogg, soon followed suit with their own references to marijuana as an appealing drug to use.
















Herd said that after rap albums celebrating marijuana use started going platinum in the early 1990s, drug references became increasingly common in rap music, as if they were a key ingredient to success.



"There is a common perception that drugs and rap music are inextricably linked, but that wasn't always the case," said Herd. "The fact that rap music didn't always have those drug references is compelling because it shows that this music didn't depend on that as an art form. The direction of the music seemed to change with the music's growing commercial success."



Herd's analysis stopped at 1997, but she noted that a recent study suggests the continued prevalence of substance abuse references in contemporary rap music. That study, led by Dr. Brian Primack from the University of Pittsburgh's School of Medicine, found that of Billboard's 279 most popular songs in 2005, a staggering 77 percent of the 62 rap songs portrayed substance use, often in the context of peer pressure, wealth and sex. He also found that only four of the 279 songs analyzed contained an "anti-use" message, and none of them was in the rap category.



Notably, other music genres had far lower rates of substance abuse references. Country music came in a distant second to rap with 36 percent of songs referencing substance abuse.



Herd noted that the image that rap artists portray of drug use in the African American community distorts reality. "Young black people actually have similar or lower rates of drug and alcohol abuse compared with their white peers, but you wouldn't guess that based upon the lyrics in rap music," said Herd.



The reasons behind rap music's shift in drug references are complex, said Herd. They may reflect the nuanced interplay of changes in the drug use habits of rappers and listeners - particularly the growing popularity of marijuana during the study period - greater commercialization of rap music, and the rise of gangsta rap and other rap music genres. It could also be a reflection of social rebellion stemming from the disproportionate punishment of African Americans in the U.S. government's War on Drugs.



"Rap is inherently powerful," said Herd. "It has experienced phenomenal growth in many sectors of society in this country and even abroad. Rap artists have become key role models and trendsetters, and their music serves as the CNN for our nation's young people by providing them with a way to stay current. But we have to ask ourselves whether there are other kinds of messages rap music could deliver. We need to better understand how this trend got started so we can find effective ways to counter it."



Herd did not study whether rap music's glamorization of illegal drugs actually led to increased drug abuse, but the debate about the potentially negative influence on young people of various media, from movies to music to video games, that depict drug and alcohol use in a positive light is certainly not new.



Herd's paper cited other studies linking certain movies and music videos to the onset of smoking, alcohol and drug use. One study specifically linked greater exposure to rap music videos to a greater risk of alcohol and drug use among adolescents over the next 12 months, while another survey associated the use of codeine-laced cough syrup among some at-risk Houston teens with an emerging form of rap music called "screw music," in which cough medicine abuse was promoted.



"Most adults have very little idea about what's going on in music these days," said Herd. "This new study reinforces the need for adults to pay closer attention to the music children are listening to."



This study is part of a larger research project analyzing changes in rap music funded by the Innovators Combating Substance Abuse program of The Robert Wood Johnson Foundation, the nation's largest philanthropic organization devoted exclusively to health care.



Through this project, Herd published an earlier study that found a significant increase in references to alcohol in rap music over the years, and she is now analyzing rap music's depiction of violence.

Alcohol Consumption After Breast Cancer Diagnosis May Increase Recurrence Risk

In the Life After Cancer Epidemiology (LACE) study, 1,897 participants diagnosed with early-stage breast cancer between 1997 and 2000 and recruited on average 2 years post-breast cancer diagnosis were evaluated for the association between alcohol intake and breast cancer recurrence and death. The women, who were generally light drinkers, were followed for an average of 7.4 years. The study reported an increase in risk of breast cancer recurrence and breast cancer death, but no effect on total mortality, to be associated with consumption of 3 to 4 or more drinks per week when compared with women not drinking following their cancer diagnosis.



Previous research has been mixed on this topic. Almost all large studies have shown no increase in all-cause mortality for women who drink moderately following a diagnosis of breast cancer (as does this study). As for recurrence of breast cancer, most have shown no increase in risk, although one previous study of women with estrogen-receptor + tumors found an increased risk of a primary cancer developing in the contralateral breast to be associated with alcohol intake of more than 7 drinks per week.



Because of conflicting results among studies on this topic, further research will be needed to determine the extent to which alcohol following a diagnosis of breast cancer may relate to subsequent disease and death.

Multiple Childhood Maltreatments Can Lead To Greater Adolescent Binge Drinking

Researchers from Boston University found that multiple types of child maltreatment are robust risk factors for underage binge drinking based on a national multi-year study that explored the influence of social environment on the health of adolescents.



The research, which appears in the current issue of Addictive Behaviors, explored how binge drinking - consuming five or more alcoholic drinks on a single occasion at least once every two weeks - occurs more frequently when there are multiple categories of maltreatments. Researchers examined the relationship of binge drinking with the co-occurrence of specific maltreatments. These included neglect, physical abuse only, sexual abuse, neglect and physical abuse and the combination of neglect, physical and sexual abuse.



Adolescents, those between the ages of 12 and 21, with a sexual abuse history had more than two-fold greater odds of reporting binge drinking than those with no maltreatment. Teenagers who had experienced both neglect and physical abuse had 1.3 times higher odds of reporting binge drinking than those with no maltreatment while adolescents that experienced all three types of maltreatment were about 1.8 times more likely to report binge drinking. The study accounted for age, gender, race/ethnicity and parental alcoholism - which were strongly associated with adolescent binge drinking.



The authors noted that while other studies have reported that child maltreatment increases an individual's risk for alcohol abuse, only a few studies have examined the effect of childhood maltreatment on adolescent binge drinking. This association is important for understanding the common pattern of alcohol consumption among adolescents with child abuse and neglect.



"Research examining the effect of childhood maltreatment on later alcohol abuse needs to recognize the clustering effects of multiple types of childhood maltreatment on alcohol problems," the study noted.



The findings were based on the National Longitudinal Study of Adolescent Health which included a nationally representative sample of 12,748 adolescents who underwent a series of three interviews about their social environment between 1995 and 2002. The maltreatment questions were asked in the third interview using a computer-assisted self-interviewing method. Parental alcoholism, education and income were based on parental respondents, not adolescent participants.



"We now have strong evidence indicating that adverse childhood experiences such as child maltreatment increases an individual's risk for alcohol problems in adolescence," said Sunny Hyucksun Shin, Assistant Professor of Human Behavior in the Social Environment at Boston University's School of Social Work. "The new challenges we face in substance use research is to identify developmental mechanisms that link childhood maltreatment to heavy episodic drinking in adolescence that can be targeted in the future development of prevention intervention."
















Adolescent binge drinking, the authors note, is a major public health problem, accounting for nearly one-fifth (18.8%) of the 10.8 million underage drinkers aged 12 to 20, according to 2005 data in the National Survey on Drug Abuse Health. The problems are greater in males (21.3%) than females (16.1%).



The prevalence of underage drinking has been linked to a host of immediate and long-term adverse outcomes, most notably obesity and high blood pressure, headaches, and concentration difficulties that leads to trouble learning and remembering. In addition to poor academic achievement, binge drinking has led to unprotected sexual activity, unsafe driving practices and motor vehicle accidents.



"Researchers examining the relationship between childhood maltreatments and risky alcohol use in adolescence should simultaneously consider all types of childhood maltreatment to address the totality of the child's experience," the authors concluded.

Edwards, project manager at Boston University Data Coordinating Center and Timothy Heeren, Professor of Biostatistics at Boston University's School of Public Health (BUSPH).

Near Misses Are Like Winning To Problem Gamblers

The brains of problem gamblers react more intensely to near misses than casual gamblers, new research from the University of Cambridge has found. The results could help explain what keeps problem gamblers betting even though they keep losing.



The study involved scanning the brains of 20 gamblers using functional magnetic resonance imaging while they played a computerised slot machine. Participants' gambling habits ranged from regular, social gamblers to those with severe problem gambling.



Dr Luke Clark of the University of Cambridge, who led the study, found that the parts of the brain involved in reward processing - the so-called dopamine centres - were more active in problem gamblers than in social gamblers.



During the experiment, volunteers played a computerised slot machine with two spinning wheels of icons and won 50p when the two icons matched. An icon mismatch was a loss, but when the wheels stopped within one icon of a match, the outcome was considered a "near miss."



Dr Clark found that near misses activated the same brain pathways as wins, even though no reward was given, and that this reaction was stronger in those gamblers who had more symptoms of problem gambling.



In particular, the study found strong responses in the midbrain, an area that is packed with dopamine-releasing brain cells. The dopamine system is associated with addiction and targeted by drugs of abuse. The study also found the near misses were linked with increased activity in a brain region called the ventral striatum, an area associated with reward and learning.



The results help explain why problem gamblers find it hard to give up.



According to Dr Clark: "These findings are exciting because they suggest that near-misses may elicit a dopamine response in the more severe gamblers, despite the fact that no actual reward is delivered. If these bursts of dopamine are driving addictive behaviour, this may help to explain why problem gamblers find it so difficult to quit."



Dopamine, a neurotransmitter, plays an important role in signalling "rewards" such as money and chocolate, and the dopamine system is also targeted by drugs of abuse.



"The results highlight some of the links between problem gambling and drug addiction, and have implications for both psychological and drug treatment for problem gamblers," Dr Clark says.



The findings are published in the new issue of the Journal of Neuroscience.



Notes:


Henry W Chase and Luke Clark, 'Gambling severity predicts midbrain response to near-miss outcomes' was published in the Journal of Neuroscience on Wednesday 5 May 2010.


Problem or 'pathological' gambling is a recognised psychiatric diagnosis, where people lose control over their gambling behaviour. The symptoms of problem gambling include cravings to gamble, going back on another occasion to recover debts ('loss chasing'), and betting larger sums of money over time. Although only 1% of the population meet the full criteria for diagnosis, several symptoms of problem gambling are common in regular players, and the volunteers in this study were recruited from the general community in and around Cambridge, rather than a treatment centre.


The research was supported by the Responsibility in Gambling Trust (now the Responsible Gambling Fund), and conducted in the University of Cambridge Behavioural and Clinical Neuroscience Institute, supported by the Medical Research Council and the Wellcome Trust.

California Alcohol Problems Drain $38 Billion Annually

Marin Institute, the
alcohol industry watchdog, held a news conference and town hall meeting in
Los Angeles today to release the disturbing findings of its landmark
report, The Annual Catastrophe of Alcohol in California. Such a
comprehensive study has never been done in California.



Before a large gathering of public health experts, policymakers, and
community activists, digital clocks ticked away in real time the incredible
economic costs ($1,200 per second or $38.4 billion annually), incidents of
harm (100 per hour or 921,928 annually) and deaths (1 per hour or 9,439
annually).



Marin's study calculates that moderate-to-high alcohol consumption in
California is costing roughly $1,000 per resident. By comparison, tobacco
costs California approximately $550 per resident. The study also estimates
$25.3 billion in lost productivity and reduced earnings.



"What makes these study results both so complex and so tragic is how
alcohol-related harm takes so many forms and affects so many lives," said
Michele Simon, Marin Institute research and policy director. Simon
co-authored the report with Ted Miller of the Pacific Institute for
Research and Evaluation and Simon Rosen, Marin Institute research analyst.



Marin Institute compared the economic losses to those from natural
disasters and concluded that alcohol costs far outpace earthquakes and
fires. Unlike earthquakes, fires, floods and mudslides, which come along
infrequently, the catastrophe of alcohol in California happens annually,
with devastating effects, and can be prevented." Rosen noted.



The study also estimates an additional $48.8 billion in quality of life
costs, due to the pain and suffering of victims and families. "These harms
are not just economic, they are also deeply personal. Quantifying the pain
and suffering endured by numerous people from alcohol harm may be the most
compelling result of this study," Rosen added.



Librarian and community activist, Manya Anderson, a life-long resident
of South Los Angeles, continues to witness firsthand the devastation of
alcohol in her own family as well as in the communities of South L.A. "As
residents, it is clear to us that both African American and Latino families
have borne the brunt of the alcohol industry's sale of liquor in our
communities. More liquor in our community means poor health and a lack of
safety."



California State Senator Mark Ridley-Thomas (D-Los Angeles) observed
that "Whether it's consumed as a vintage wine from a prestigious
appellation or a fortified variant, a micro-brew or malt liquor, an alcopop
or high-end distilled spirit, alcohol's cost is much more than the price
paid for a drink at the corner liquor store or neighborhood bar." He added,
"As a legislator, I am looking forward to engaging my colleagues along with
representatives of the industry in a discussion of the report's findings
and recommendations."



Marin Institute is calling for a number of steps to reverse the
catastrophe, including higher alcohol taxes to reduce excessive consumption
and the related harm and costs. While the harmful cost of alcohol is equal
to $2.80 per drink, current alcohol taxes come to only 8 cents per drink.
"The alcohol lobby has been very effective in minimizing their taxes and
fees to just 1.7 percent of their income from sales," noted Bruce
Livingston, Marin Institute's executive director. "It's time we hold Big
Alcohol accountable by getting them to pay their fair share."



Jonathan E. Fielding, M.D., MPH, Public Health Officer and Director of
the County of Los Angeles Public Health Department said, "Marin Institute's
report is a much needed reminder of the harm and costs associated with
alcohol consumption in California."



The study will be published next month by the peer-reviewed journal,
Alcoholism: Clinical and Experimental Research. To download study findings

A New Indicator For Esophageal Varix In Alcoholic Disease

Variceal hemorrhaging is associated with a high mortality rate. The early detection of esophageal varices is critical for the effective prevention of variceal hemorrhage.



In daily medical practice, it is common to encounter patients with liver damage from chronic alcohol consumption. When the alcoholic patient is examined, it is often evident that alcoholic liver damage is progressing. Once alcoholic cirrhosis is established, esophageal varices develop in the majority of patients, as found during prolonged follow-up. Nevertheless, alcoholic patients tend to be indifferent regarding their health, and are not likely to undergo periodic consultations. The research team therefore examined the predictive factors for esophageal varices in severe alcoholic disease.



An article published in the World Journal of Gastroenterology describes the predictive factors. A study was reported by Dr. Satoshi Mamori, of Jikei University, in which he analyzed the background of alcoholic patients to predict the occurrence of esophageal varices.



Abdominal ultrasonography (US) was performed on 444 patients suffering from alcoholism. The alcoholic patients with splenomegaly and/or withering of the right lobe of the liver were defined as severe alcoholic disease patients (SAD) and participated as the study subjects. The SAD patients were observed by upper gastrointestinal (UGI) endoscopy to evaluate the development of esophageal varies. The existence of esophageal varices was then compared according to a number of clinical background variables.



44 patients were identified as SAD patients. Twenty-five patients (56.8%) had esophageal varices, and a univariate analysis revealed a significant difference in the age and type IV collagen levels between the patients with and without esophageal varices. Moreover, a logistic regression analysis identified only one independent variable predictive of esophageal varices: type IV collagen (P = 0.017). The area under the curve of type IV collagen, as determined by the receiver operating characteristic for predicting expressed esophageal varices, was 0.78.



The combination of abdominal ultrasound scan and type IV collagen correctly identified, at a high rate, the patients with esophageal varices.

Tackling alcohol misuse - What works best?

The UK Health Development Agency today publishes its report on the prevention of alcohol misuse. The updated edition of
the briefing document 'Prevention and reduction of alcohol misuse' highlights what works in tackling alcohol misuse, any gaps
in the evidence and puts forward recommendations for policy and research commissioners.


The report examines interventions to combat the damaging effects of alcohol and the burden placed by alcohol on the NHS.
Statistics show that in 2002, 27% of men and 17% of women aged 16 and over drank on average more than the recommended weekly
safe amounts of 21 and 14 units respectively. 40% of all A&E admissions are alcohol related, and as many as 150,000 hospital
admissions each year are related to alcohol misuse.


The recommendations include specific interventions such as behavioural counselling in healthcare settings to reduce risky and
harmful alcohol consumption. There is evidence to support that brief advice sessions given in this setting could reduce
weekly drinking by up to 34%, which could result in an average of nearly 9 fewer drinks per week. On the roads, evidence
supports the effectiveness of breath-test ignition systems (interlocks) and introducing a lower legal maximum blood alcohol
concentration to reduce alcohol-impaired crash deaths, particularly among younger drivers.


Professor Mike Kelly, HDA director of Evidence and Guidance, said:


"The need for effective interventions to reduce the negative impact of alcohol is clear - up to 22,000 deaths each year are
associated with alcohol misuse, up to 17 million working days are lost annually due to alcohol related absence, and overall,
it is estimated that the costs of alcohol misuse are around ?20billion a year.


This evidence briefing highlights the most effective ways of tackling alcohol misuse, showing that advice from healthcare
professionals can help reduce levels of drinking, and providing the evidence on the best methods of reducing alcohol-impaired
driving."


The briefing identifies a number of inequalities and vulnerable groups, but finds a lack of review-level evidence for the
effectiveness of interventions in reducing alcohol misuse in these sections of the community. The briefing recommends that
research is needed on which approaches work best among minority ethnic groups, and identifies an urgent need to fill the
evidence gap to reduce alcohol misuse in young people.


The policy context is also summarised, reiterating that combating alcohol-related crime and disorder is a key requirement to
address the problems of town and city centres that are affected by alcohol misuse at weekends. This includes greater
adoption of policies such as exclusion orders to ban those causing trouble from pubs, clubs or entire town centres and
greater enforcement of existing rules on under age drinking, and serving those who are drunk - evidence shows that bartender
training is effective in reducing intoxication levels in customers. It also stresses the importance of working with the
alcohol industry to build on the good practice of some existing initiatives such as Citysafe schemes.
