Law compliance, why do we need it? Comparative data from the Brazilian National Survey of School Health (PeNSE) on adolescents' access to cigarettes.

In recent decades, Brazil has made significant progress in fighting the tobacco epidemic. However, recent national data suggest a probable stagnation in the reduction of smoking initiation among youth and adolescents. The objective of this study was to evaluate the evolution over time of compliance with the law that prohibits the sale of cigarettes to minors in Brazil. To this end, data from the Brazilian National Survey of School Health conducted in 2015 and 2019 were used. Percentages were estimated for "sequential" indicators created by combining answers to the questions "Did anyone refuse to sell you cigarettes?" and "How did you obtain your cigarettes?" There was a decrease between 2015 and 2019 in the percentage of smokers aged 13 to 17 who tried to buy cigarettes in the 30 days prior to the survey (72.3% vs. 66.4%; p-value ≤ 0.05). However, regardless of the survey year, approximately 9 out of 10 adolescent smokers were successful in an attempt to buy cigarettes. Of those, approximately 7 out of 10 used direct purchase as the main method of obtaining cigarettes, with purchases at licensed commercial establishments (vs. street vendors) increasing between 2015 and 2019 (81.1% vs. 89.6%; p-value ≤ 0.05). In 2019, 70% of teenagers who bought cigarettes at licensed commercial establishments purchased single cigarettes. Non-compliance with laws aimed at preventing smoking initiation is a huge obstacle to reducing the proportion of smokers. Increased implementation of legislative measures and oversight of cigarettes sales, combined with educational and awareness actions with retailers, is key to protecting new generations from the harmful effects of tobacco use.
