Abstract:
In the 32 western countries that participated in the Health behaviour in school-aged children (HBSC 2002) survey conducted in schools, about 20% of 15-year-olds declared that they had already used cannabis, which is consequently the third most frequently consumed psychoactive substance after alcohol and tobacco. Boys are heavier consumers than girls in every country. France is one of the ten countries with the highest cannabis use rates among 15-year-olds (29,8%). A correlation was observed between daily tobacco and alcohol consumption, frequent drunkeness and passage from experimental use to more frequent use.
