The current study examined the prevalence of alcohol, tobacco and drug use and comorbid use of these substances among 45,425 students in grades 7 to 12 as part of the 2008-09 Canadian Youth Smoking Survey. The results of this paper suggest that alcohol, tobacco, marijuana and illicit drugs are currently used by a substantial number of youth in Canada, and that comorbid use is also very widespread among users. Alcohol was the most prevalent substance used by youth and it was rare to find youth who had used tobacco or drugs without also currently using alcohol. By grade 12, the majority of students were current users of alcohol, tobacco or drugs. Future research should consider developing a better understanding of how to prevent substance use among this population.
本研究调查了 45425 名 7 至 12 年级学生的酒精、烟草和药物使用情况，以及这些物质的合并使用情况，这是 2008-09 年加拿大青少年吸烟调查的一部分。本文的结果表明，在加拿大，相当数量的青少年目前使用酒精、烟草、大麻和非法药物，而且使用者中也存在广泛的合并使用现象。酒精是青少年最常使用的物质，很少发现有青少年仅使用烟草或药物而不使用酒精。到 12 年级时，大多数学生是酒精、烟草或药物的当前使用者。未来的研究应该考虑如何更好地理解如何预防这一人群的物质使用。
