Brazil
Brazil was the second country in the world and the first country in Latin America to adopt mandatory warning images in cigarette packages. Warnings and graphic images illustrating the risks of smoking occupy 100% of the back of cigarettes boxes since 2001. In 2008, the government elected a third batch of images, aimed at younger smokers.
Since 2003, the sentence
Este produto contém mais de 4,7 mil substâncias tóxicas, e nicotina que causa dependência física ou psíquica. Não existem níveis seguros para consumo dessas substâncias. (This product contains over 4700 toxic substances and nicotine, which causes physical or psychological addiction. There are no safe levels for the intake of these substances.)is displayed in all packs.
In addition to the above sentence, the message "O Ministério da Saúde adverte: ..." (The Health Ministry warns: ...), followed by one of the many known risks of smoking, is shown on one of the sides. The same introduction, followed by a warning, was spoken after TV commercial advertisements; and even now that cigarette ads are no longer allowed, it retains great popularity and is used in a number of different contexts, health-related or not.
