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.

The article presents the author's views on the article "Reducing intoxication among bar patrons: some lessons from prevention of drinking and driving," by K. Graham and colleagues. The paper was focused on the enforcement of the laws for restricting the intoxication among bar patrons. Role of corporate social responsibility (CSR) in the formation of laws for drinking and driving is discussed.

A response from the authors of the article "Reducing the legal blood alcohol concentration limit for driving in developing countries: a time for change? Results and implications derived from a time-series analysis (2001–10) conducted in Brazil" which was published in a previous issue is presented.

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.

ABSTRACT Aims To examine the proportion of self-reported alcohol consumed by different gender and age groups in Brazil over the past year, and to examine whether the 'prevention paradox' applies to Brazilian data on alcohol-related problems. Design A multi-stage cluster sample, representative of the Brazilian household population. Setting This study was conducted in Brazil between November 2005 and April 2006. Participants Respondents were aged ≥ 14 years (n = 3007). Measurements Measures included past year estimates of (i) number of standard drinks, (ii) frequency of binge drinking, and (iii) alcohol-related problems. Findings The survey response rate was 66.4%. The top 2.5% of the drinkers by volume consume 14.9%, the top 5% consume 27.4% and the top 10% consume 44.2% of all alcohol consumed in Brazil. Men consume 77.8% of the total alcohol, and 18-29-year-olds consume 40.3%. Individuals below risky drinking guidelines for weekly volumetric intake account for 49-50% of all problem drinkers and 45-47% of all problem types reported. Individuals who do not binge or who binge infrequently (1-3 times/year) account for 50-51% of all problem drinkers and 45-46% of all reported problem types. Most binge drinkers are low-volume drinkers. Conclusions Consistent with the prevention paradox literature, most drinking problems in Brazil are associated with low or moderate drinking. Binge drinking accounts more clearly for the distribution of alcohol problems than total volume consumed. [ABSTRACT FROM AUTHOR]

The author discusses the article on alcohol use in Brazil and its prevention paradox by R. Caetano and colleagues. He says that the article provides an anatomy of drinking patterns and related problems in the country with both high rates of alcohol consumption disorders and abstention. He states that there is no such thing as fully risk-free drinking. He mentions the use of the prevention paradox to promote public health policies limiting he physical and economic availability of alcohols.
