Selected AbstractsCREDIBLE RESEARCH PRACTICES TO INFORM DRUG LAW ENFORCEMENTCRIMINOLOGY AND PUBLIC POLICY, Issue 3 2003CHARLES F. MANSKI Chairing the recent National Research Council Committee on Data and Research for Policy on Illegal Drugs, I learned that our nation has invested little in research on drug law enforcement and that the limited available research does not provide a credible basis for formation of drug control policy. This commentary conjectures reasons for the distressing status quo and recommends changes in research practices that may improve matters. [source] Supply control and harm reduction: lessons from the Australian heroin ,drought'ADDICTION, Issue 1 2003Don Weatherburn ABSTRACT Aims, To examine the effects of supply-side drug law enforcement on the dynamics of the Australian heroin market and the harms associated with heroin. Setting, Around Christmas 2000, heroin users in Sydney and other large capital cities in Australia began reporting sudden and significant reductions in the availability of heroin. The changes, which appear to have been caused at least in part by drug law enforcement, provided a rare opportunity to examine the potential impact of such enforcement on the harm associated with heroin. Design, Data were drawn from a survey of 165 heroin users in South-Western Sydney, Australia; from the Drug Use Monitoring in Australia (DUMA) project; from NSW Health records of heroin overdoses; and from the Computerized Operational Policing System (COPS) database. Findings, Heroin price increased, while purity, consumption and expenditure on the drug decreased as a result of the shortage. The fall in overall heroin use was accompanied by a significant reduction in the rate of overdose in NSW. However, the health benefits associated with the fall in overdose may have been offset by an increase in the use of other drugs (mainly cocaine) since the onset of the heroin shortage. There does not appear to have been any enduring impact on crime rates as a result of the heroin ,drought'. Conclusion, Supply control has an important part to play in harm reduction; however, proponents of supply-side drug law enforcement need to be mindful of the unintended adverse consequences that might flow from successfully disrupting the market for a particular illegal drug. [source] Youth Risk Behavior Surveillance , United States, 2001JOURNAL OF SCHOOL HEALTH, Issue 8 2002Jo Anne Grunbaum ABSTRACT: Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, are interrelated, and are preventable. This report covers data during February-December 2001. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority healthrisk behaviors among youth and young adults; these behaviors contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection; unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by CDC as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 34 state surveys, and 18 local surveys conducted among students in grades 9,12 during February-December 2001. In the United States, approximately three-fourths of all deaths among persons aged 10,24 years result from only four causes: motor-vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 2001 national Youth Risk Behavior Survey demonstrated that numerous high school students engage in behaviors that increase their likelihood of death from these four causes: 14.1% had rarely or never worn a seat belt during the 30 days preceding the survey; 30.7% had ridden with a driver who had been drinking alcohol; 17.4% had carried a weapon during the 30 days preceding the survey; 47.1% had drunk alcohol during the 30 days preceding the survey; 23.9% had used marijuana during the 30 days preceding the survey; and 8.8% had attempted suicide during the 12 months preceding the survey. Substantial morbidity and social problems among young persons also result from unintended pregnancies and STDs, including HIV infection. In 2001, 45.6% of high school students had ever had sexual intercourse; 42.1% of sexually active students had not used a condom at last sexual intercourse; and 23% had ever injected an illegal drug. Two-thirds of all deaths among persons aged ,25 years result from only two causes: cardiovascular disease and cancer. The majority of risk behaviors associated with these two causes of death are initiated during adolescence. In 2001, 28.5% of high school students had smoked cigarettes during the 30 days preceding the survey; 78.6% had not eaten ,5 servings per day of fruits and vegetables during the 7 days preceding the survey; 105% were overweight; and 67.8% did not attend physical education class daily. Health and education officials at national, state, and local levels are using these YRBSS data to analyze and improve policies and programs to reduce priority health-risk behaviors among youth. The YRBSS data also are being used to measure progress toward achieving 16 national health objectives for 2010 and 3 of the 10 leading health indicators. [source] Global burden of disease from alcohol, illicit drugs and tobaccoDRUG AND ALCOHOL REVIEW, Issue 6 2006JÜRGEN REHM PhD Abstract The use of alcohol, tobacco and illicit drugs entails considerable burden of disease: in 2000, about 4% of the global burden as measured in disability adjusted life years was attributable to each alcohol and tobacco, and 0.8% to illicit drugs. The burden of alcohol in the above statistic was calculated as net burden, i.e. incorporating the protective health effects. Tobacco use was found to be the most important of 25 risk factors for developed countries in the comparative risk assessment underlying the data. It had the highest mortality risk of all the substance use categories, especially for the elderly. Alcohol use was also important in developed countries, but constituted the most important of all risk factors in emerging economies. Alcohol use affected younger people than tobacco, both in terms of disability and mortality. The burden of disease attributable to the use of legal substances clearly outweighed the use of illegal drugs. A large part of the substance-attributable burden would be avoidable if known effective interventions were implemented. [source] Drug-related behaviors independently associated with syphilis infection among female sex workers in two Mexico,US border citiesADDICTION, Issue 8 2010Oralia Loza ABSTRACT Aims To identify correlates of active syphilis infection among female sex workers (FSWs) in Tijuana and Ciudad Juarez. Design Cross-sectional analyses of baseline interview data. Correlates of active syphilis (antibody titers >1 : 8) were identified by logistic regression. Setting Tijuana and Ciudad Juarez, two Mexican cities on the US border that are situated on major drug trafficking routes and where prostitution is quasi-legal. Participants A total of 914 FSWs aged ,18 years without known human immunodeficiency virus (HIV) infection who had had recent unprotected sex with clients. Measurements Baseline interviews and testing for syphilis antibody using Treponema pallidum particle agglutination (TPPA) and rapid plasma reagin (RPR) tests. Findings Median age and duration in sex work were 32 and 4 years, respectively. Overall, 18.0% had ever injected drugs, 14.2% often or always used illegal drugs before or during sex in the past month, 31.4% had clients in the last 6 months who injected drugs, and 68.6% reported having clients from the United States. Prevalence of HIV and active syphilis were 5.9% and 10.3%, respectively. Factors independently associated with active syphilis included injecting drugs (AOR: 2.39; 95% CI: 1.40, 4.08), using illegal drugs before or during sex (AOR: 2.06; 95% CI: 1.16, 3.65) and having any US clients (AOR: 2.85; 95% CI: 1.43, 5.70). Conclusions Among female sex workers in Tijuana and Ciudad Juarez, drug-using behaviors were associated more closely with active syphilis than were sexual behaviors, suggesting the possibility of parenteral transmission of T. pallidum. Syphilis eradication programs should consider distributing sterile syringes to drug injectors and assisting FSWs with safer-sex negotiation in the context of drug use. [source] What economics can contribute to the addiction sciencesADDICTION, Issue 7 2010Jonathan P. Caulkins ABSTRACT Aims The addiction sciences are intrinsically multi-disciplinary, and economics is among the disciplines that offer useful perspectives on the complex behaviors surrounding substance abuse. This paper summarizes contributions economics has made in the past and could make in the future towards understanding how illegal markets operate, how prices affect use, how use generates various consequences, and how policy shapes all three. Methods Review of literature, concentrating on illegal drugs as insights concerning markets are particularly salient, although we also mention relevant studies from the alcohol and tobacco fields. Findings and Conclusions Economics offers tools and topical expertise that usefully complement other disciplines associated traditionally with the addiction sciences. Its value goes far beyond the ability to monetize non-monetary outcomes or to calculate a cost-benefit ratio. [source] Changes in women's use of illicit drugs following imprisonmentADDICTION, Issue 2 2009Emma Plugge ABSTRACT Aim To provide data on changes in illegal drug use in women following imprisonment. Design Prospective cohort study. Setting Recruitment took place in two prisons in the Midlands and South-East England and follow-up in 13 prisons across England. Participants A total of 505 women prisoners participated, a response rate of 82%. Measurements Questions about drug use were contained within a questionnaire which examined broad aspects of health. On entry into prison, women answered questions about daily drug use and injecting drug use prior to imprisonment. One month later the questionnaires examined drug use during this period of imprisonment. Findings Prior to imprisonment, 53% [95% confidence interval (CI): 49,58%] of women took at least one illegal drug daily and 38% (CI: 34,42%) said they had ever injected drugs. Following imprisonment, some women continued to use drugs; 14% (CI: 10,20%) of women reported using at least one illegal drug daily and 2% (CI: 0.7,5%) of women had injected drugs. There were important changes in the types of drugs used; there was a change in use from crack and heroin to benzodiazepines and opiate substitutes. Prior to imprisonment, women most commonly used crack and heroin, but in prison the two most commonly used illegal drugs were benzodiazepines and opiate substitutes. Conclusions The study provides quantitative evidence of the impact of imprisonment on drug use among women. It highlights the need for enhanced drug treatment services and stronger measures to reduce the availability of illegal drugs to women in prison. [source] Childbirth, abortion and subsequent substance use in young women: a population-based longitudinal studyADDICTION, Issue 12 2007Willy Pedersen ABSTRACT Aims To investigate the possible linkages between deliveries, abortions and subsequent nicotine dependence, alcohol problems and use of cannabis and other illegal drugs from the ages of 15,27 years. Methods Data were gathered as part of the Young in Norway Longitudinal Study, an 11-year follow-up of a representative sample of Norwegian adolescents and young adults. Design, setting and participants Information was obtained on (i) the history of childbirths and induced abortions for the participants between the ages of 15,27 years; (ii) measures of nicotine dependence, alcohol problems and use of cannabis and other illegal drugs; and (iii) socio-demographic, family and individual confounding factors. Results Those who had had an abortion had elevated rates of substance use and problems. Those who gave birth to a child had reduced rates of alcohol problems and cannabis use. These associations persisted after control for confounders. However, those women who still lived with the father of the aborted fetus were not at increased risk. Conclusions Abortion in women may, under some circumstances, be associated with increased risk of nicotine dependence, alcohol problems and use of cannabis and other illegal drugs. The birth of a child may reduce the use of some substances. [source] What are the high risk periods for incident substance use and transitions to abuse and dependence?INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue S1 2008Implications for early intervention, prevention Abstract Background: For a better understanding of the evolution of addictive disorders and the timely initiation of early intervention and prevention, we have to learn when and how quickly the critical transitions from first substance use (SU) to regular use and from first SU and regular SU to abuse and dependence occur. Little data are currently available on the transitions to substance use disorders (SUDs) across the spectrum of legal and illegal drugs taking into account gender differences. It is the aim of this paper to describe the high density incidence and transition periods of SU and SUD for alcohol, nicotine, cannabis and other illicit drugs for young males and females. Methods: A sample of (N = 3021) community subjects aged 14,24 at baseline were followed-up prospectively over 10-years. SU and SUD were assessed using the DSM-IV/M-CIDI. Results: Ages 10,16 are the high risk period for first alcohol and nicotine use (up to 38% of subjects start before age 14). Onset of illegal SU occurs later. Substantial proportions of transitions to regular SU and SUD occur in the first three years after SU onset. Only few gender differences were found for time patterns of SU/SUD incidence and transition. Conclusion: Except for alcohol the time windows for targeted intervention to prevent progression to malignant patterns in adolescence are critically small, leaving little time for targeted intervention to prevent transition. The fast transitions to abuse and dependence in adolescence may be indicative for the increased vulnerability to substance effects in this time period. Basic research on the determinants of transitions should thus target this period in adolescence. Copyright © 2008 John Wiley & Sons, Ltd. [source] Carolina in the Carolines: A Survey of Patterns and Meanings of Smoking on a Micronesian IslandMEDICAL ANTHROPOLOGY QUARTERLY, Issue 4 2005Mac Marshall Tobacco use---especially smoking industrially manufactured cigarettes---kills nearly 5 million people annually and is the leading preventable cause of death worldwide. Tobacco is a widely used global commodity embedded in cultural meanings, and its consumption involves a set of learned, patterned social behaviors. Seemingly, then, tobacco offers a most appealing anthropological research topic, yet its study has been relatively ignored by medical anthropologists when compared to research on alcoholic beverages and illegal drugs. To help fill this gap, this article sketches the historical background of tobacco in Micronesia, presents the results of a cross-sectional smoking survey from Namoluk Atoll, and describes contemporary smoking patterns and locally understood symbolic associations of tobacco. Intersections among history, gender, local meanings, the health transition, and the transnational marketing of tobacco are addressed, and cigarette smoking is seen as part of a new syndemic of chronic diseases in Micronesia. [source] Ordnungspolitik auf illegalen Märkten: Der Drogen- und WaffenmarktPERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue 1 2002Hanno Beck In this paper, the economic structure of illegal markets with special reference to the markets for illegal drugs and arms is analyzed. Analytical tools of System Dynamics are employed to emphasize the dynamic aspects of these markets. The results of our analysis enable us to evaluate state intervention in the illegal markets for drugs and arms. It seems possible to mitigate the drugs problem by supplying drugs to heavily addicted people on the basis of health care measures. However, a similar policy seems not to exist for the illegal arms trade. This shows that each illegal market requires a deeper understanding before it can be fought effectively. [source] Drug Interactions between Antiretroviral Medications and Medications Used in the Treatment of Drug Addiction: Research NeedsTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 1 2010Jag H. Khalsa PhD Today substance dependence is one of the major public health problems in the world with millions of people abusing legal and illegal drugs. In addition, almost one-third of the world's population suffers with one or more infections. Both drugs of abuse and infections are associated with serious medical and health consequences, some of which may be exacerbated by the occurrence of pharmacokinetic and/or pharmacodynamic interactions between medications used in the treatment of these conditions when they co-occur. This review briefly discusses issues surrounding clinical management related to drug interactions experienced by substance abusing patients. The emphasis of this paper is on the research needed to further study the extent, nature, and underlying molecular/genetic mechanism(s) of interactions between drugs of abuse, medications used in the treatment of drug addiction, and co-occurring infections.,(Am J Addict 2009;19:96,100) [source] The Violence Proneness Scale of the DUSI-R Predicts Adverse Outcomes Associated with Substance AbuseTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 2 2009Levent Kirisci PhD Accuracy of the Violence Proneness Scale (VPS) of the Drug Use Screening Inventory (DUSI-R)1 was evaluated in 328 boys for predicting use of illegal drugs, DUI, selling drugs, sexually transmitted disease, car accident while under acute effects of drugs/alcohol, trading drugs for sex, injuries from a fight, and traumatic head injury. Boys were prospectively tracked from age 16 to 19 at which time these outcomes were documented in the interim period. The results demonstrated that the VPS score is a significant predictor of all outcomes. Prediction accuracy ranged between 62%,83%. These findings suggest that the VPS may be useful for identifying youths who are at high risk for using illicit drugs and commonly associated adverse outcomes. [source] Personality Risk Factors Associated with Trajectories of Tobacco UseTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 6 2006Judith S. Brook EdD The purpose of this longitudinal, prospective study was to evaluate trajectories of smoking in a cohort of African-American and Puerto Rican young adults and describe personality and behavioral factors associated with specific smoking trajectory group membership. Participants consisted of African-American and Puerto Rican male and female young adults (n = 451, mean age 26) from an inner-city community. Data were collected at four time points over a period of 13 years using structured interviews. Interviews took place within the schools and the participants' homes. Scales with adequate psychometric properties were adapted from previously validated measures. Variables that were examined for this study came from the domains of internalizing behaviors, externalizing behaviors, drug use, and demographic information. Data were analyzed using latent growth mixture modeling to explore discrete smoking trajectories. Logistic regression analyses were then used to examine the risk factors associated with the various smoking trajectory groups. Four trajectory groups were determined to best fit the data: nonsmokers, maturing-out smokers, late-starting smokers, and early-starting continuous smokers. Subjects who were unconventional, experienced intrapersonal distress, and used alcohol and illegal drugs were more likely to belong to one of the smoking trajectory groups than to the nonsmoking group. The early-starting continuous group scored highest on these personal risk attributes. The long-term impact of unconventional behavior, intrapersonal distress, and drug use on developmental trajectories of smoking support the importance of early intervention and prevention. [source] Marijuana Use Among the Adolescent Children of High-Risk Drug-Abusing FathersTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 2 2002David W. Brook M.D. This study examines marijuana use among children of male drug abusers. Subjects were 83 African-American and European-American male drug abusers, of whom the majority were injection drug users, and their children. Thirty-one of the fathers were HIV-positive and 52 were HIV-negative. Using logistic regression analyses, we explored cross-sectionally the relationship between four psychosocial domains (ie, paternal attributes, adolescent problem behaviors, father-adolescent relations, and environment) and adolescent marijuana use. The father's use of illegal drugs and his failure to cope adaptively predicted adolescent marijuana use, while a close father-child bond predicted less adolescent marijuana use. Adolescent problem behaviors predicted an increased likelihood of marijuana use. Furthermore, hierarchical regression analysis demonstrated that the adolescent's problem behavior mediated the associations between both the father-adolescent relationship and environmental factors with adolescent marijuana use. Reducing the risk factors and enhancing the protective factors within each of the domains could help reduce marijuana use among the adolescent children of drug-abusing fathers. Moreover, if a father is a drug abuser, it is important to help him establish a close bond with his child in order to help attenuate the influence of his drug use on the child's marijuana use.
