Introduction and Aims: Given a scenario of intense discussion about the legal situation of cannabis users worldwide, this paper aims to investigate the role of cannabis within a drug use sequencing pattern., Design and Methods: Data came from a representative sample of college students from 27 Brazilian capitals (n = 12 711). We analysed the patterns of transition from/to the first use of cannabis to/from the first use of alcohol, tobacco and seven other illegal drugs. Survival analysis methods were used to analyse age of onset data on all potential drug pairs. Drugs that were not specified as the target drug pair tested in each survival model were included as time-varying covariates in all models., Results: We found significant transitions from alcohol [adjusted hazard ratio (aHR) = 1.41, 95% confidence interval (CI) 1.15-1.73, P < 0.001] and inhalants (aHR = 1.56, 95% CI 1.26-1.93, P < 0.001) to cannabis. Moreover, we found significant transitions from cannabis to alcohol (aHR = 2.40, 95% CI 1.47-3.91, P < 0.001), cocaine (aHR = 7.47, 95% CI = 4.26-13.09, P < 0.001), prescription opioids (aHR = 2.16, 95% CI 1.29-3.63, P < 0.01) and tranquilisers (aHR = 1.51, 95% CI 1.11-2.06, P < 0.01)., Discussion and Conclusions: Overall, our findings point to a strategic role of cannabis within drug first use sequence pattern. We had an important and unexpected finding-the bi-directional relationship between alcohol and cannabis. In addition, the first use of cannabis still precedes the first use of cocaine and non-medical use of tranquilisers and prescription opioids.

Aims and design The historical and economic involvement of Brazil with tobacco, as a major producer and exporter, was considered an insurmountable obstacle to controlling the consumption of this product. Nevertheless, the country was able to achieve significant progress in implementing public policies and to take an international leadership position, meeting its constitutional commitment to protect public health. In this paper we provide a brief historical overview of tobacco control ( TC) in Brazil, and analyse the factors that contributed to the major decline in tobacco consumption in the country over the last 20 years, as well as identify the challenges that had to be overcome and those still at play. Findings The Brazilian case demonstrates how cross-sectorial collaborations among health-related groups that capitalize on their respective strengths and capacities can help to influence public policy and overcome industry and population resistance to change. Although Brazil still lags behind some leading TC nations, the country has an extensive collaborative TC network that was built over time and continues to focus upon this issue. Conclusions The tobacco experience can serve as an example for other fields, such as alcoholic beverages, of how networks can be formed to influence the legislative process and the development of public policies. Brazilian statistics show that problems related to non-communicable diseases are a pressing public health issue, and advocacy groups, policy-makers and government departments can benefit from tobacco control history to fashion their own strategies.

ABSTRACT While individual studies from several South American countries have shown driving while intoxicated to be a problem, there are no objective systematically collected alcohol-associated driving data obtained in most South American countries. This limits their ability to implement and enforce targeted prevention strategies, evaluate whether proven prevention efforts from North America (particularly the United States and Canada) can be transferred to the South, and to sustain momentum for the improvement of road safety by demonstrating that previously implemented legal and policy changes are effective. The aim of this paper is to discuss the abysmal differences that exist between northern and southern American countries regarding the current status of driving while intoxicated prevention strategies-their implementation, impacts and effects-using Brazil as a case example. We propose a three-pronged approach to close this northern-southern American gap in driving while intoxicated prevention and intervention: (a) systematic collection on road traffic crash/injury/death as well as risk factor data, (b) passage of laws without loopholes requiring compliance with blood alcohol concentration testing and (c) provision of appropriate training and equipment to the police in concomitance with vigilant enforcement. Resources and energies must be put towards data collection, implementation of prevention strategies and enforcement in order to decrease the unacceptably high rates of these preventable driving while intoxicated deaths.

The author comments on the paper "Why don't northern American solutions to drinking and driving work in southern America?" by F. Pechansky and A. Chandran, which addresses the lack of policies regarding drinking and driving. According to her, lack of data or laws is not a problem in Brazil but lapses in the enforcement of existing laws is. She refers to several studies on drunk driving and suggests acquiring a better understanding of the problem through research and monitoring.

The author comments on the article "Why don't northern American solutions to drinking and driving work in southern America?" by F. Pechansky and A. Chandran. She highlights the points addressed by the authors of the study regarding aspects lacking in Brazil and notes that the issue of advocacy and active popular support is not taken into consideration by the study. She opines that active participation as a critical factor to tackle the state of affairs of drinking and driving rates.

Comments on the editorial of Raul Caetano in the March 1989 issue of the 'British Journal of Addiction' about alcohol research in Latin America, particularly Brazil. Trends in alcohol production in Brazil in 1987; Information on the focus of alcohol research conducted by research institutes and groups in Brazil; Organization of the Brazilian Association for Studies on Alcohol and Alcoholism.

The aim of this study was to compare three groups of Brazilian psychoactive substance (PAS) abuse patients (crack cocaine users, cocaine snorters, and non-cocaine PAS users) in terms of psychiatric comorbidities and severity of psychosocial problems. A cross-sectional, multi-center study was conducted at five Brazilian research centers. A total of 738 current PAS abusers seeking specialized treatment (outpatient and inpatient clinics) were assessed using the sixth version of the Addiction Severity Index (ASI-6): 293 patients using crack cocaine were compared with 126 using powder cocaine and 319 using non-cocaine PAS (mostly alcohol and marijuana). Psychiatric comorbidities were assessed in a smaller sample (290 cases), originating from three of the centers, using the Mini International Neuropsychiatric Interview Plus (MINI-Plus). Crack and powder cocaine users were significantly younger than non-cocaine PAS users (31.1 ± 8.1 and 32.9 ± 8.8 vs. 42.4 ± 12, respectively; p < .001). Crack users presented a higher rate of antisocial personality disorder (25%) than powder cocaine (9%) and non-cocaine PAS users (9%), even when adjusted for confounding factors (Pr = 2.6; 95% CI 1.10-6.40). According to ASI-6 summary scores, crack users presented a significantly higher rate of occupational, family, and legal problems and reported more illegal and violent activities such as burglary and theft (23%) and threatening or assaulting (32%) than non-cocaine PAS users. Our findings, combined with the recent increase observed in the prevalence of crack use in Brazil, highlight the severity of psychiatric symptoms and psychosocial problems related to this powerful drug and corroborate the already suggested association between crack/cocaine, violence, and legal problems. Treatment programs for crack users should routinely consider the possibility of associated psychiatric comorbidities, such as antisocial personality disorder, which may affect treatment outcomes.

An interview with alcohol epidemiologist Raul Caetano is presented. When asked about the role of Brazil in his personal and professional development, he refers to the amalgam of African and European culture. He says that people of Brazil have developed their own resources for difficulties as they do not depend on the government. He believes that alcohol-related problems arise due to availability of low-cost alcohol. He comments on high rate of alcohol dependence.

ABSTRACT Aims To assess the prevalence of potential alcohol use disorders and associated factors using the Alcohol Use Disorders Identification Test (AUDIT). Design Cross-sectional study. Setting A town in southern Brazil. Participants A representative sample of 1260 people aged 15 and over. Measurements Demographic, socioeconomic, smoking habit and mental health data were collected. Logistic regression was used in the multivariate analysis, and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Findings Overall prevalence of alcohol use disorder was 7.9%, with 14.5% prevalence among men and 2.4% among women. The risk of alcohol misuse increased across social class (P linear trend = 0.03) and compared with the highest classes (A and B), groups C through E had ORs of 1.48, 1.51 and 2.36, respectively. Males had an OR of 6.89 (CI 3.61–13.16) compared with women. A linear trend was found (P = 0.001) between smoking categories, and smokers (OR 3.27; CI 1.91–5.58) and ex-smokers (OR 1.30; CI 0.56–2.98) were at higher risk than non-smokers. Those with minor psychiatric disorders had a 2.48 OR (CI 1.35–4.56) of presenting a positive test. Conclusions The AUDIT detected a high prevalence of potential alcohol use disorders in the population sampled. Those identified are potential targets for preventive measures implemented through health policies. [ABSTRACT FROM AUTHOR]

Objectives: To estimate the prevalence and risk groups of domestic violence during pregnancy among public health care users in Rio de Janeiro, Brazil. The study focuses on violence perpetrated by both women and partners. Method: 526 women giving birth at term in public maternities from March to October 2000 were randomly selected and interviewers used the Revised Conflict Tactics Scales (CTS2). Results: 33.8% [95% confidence interval (CI): 28.8–37.0%] of the respondents reported some form of physical violence and 16.5% (95% CI: 13.3–19.8%) referred to severe forms. A total of 78.3% (95% CI: 74.8–81.8%), 9.9% (95% CI: 7.5–12.7%) and 15.6% (95% CI: 12.6–18.9%) reported psychological aggression, sexual coercion and injuries, respectively. Physical violence mainly occurred among adolescent women with less schooling, who did not work outside the home, with fewer prenatal appointments, and with little social support. Families with more under-five children, alcohol and drug abuse, and low socio-economic status were also involved more frequently. Conclusion: High prevalence rates for various forms of domestic violence in Brazil suggest that the issue should be viewed as a major public health problem. [Copyright &y& Elsevier]
