Abstract
The purpose of this paper is to describe cross-national differences in drug use and violence among three sites that vary in social and political culture and drug use policies—Philadelphia, Toronto, and Amsterdam. The DAVI (Drugs, Alcohol and Violence International) study is based on personal interviews with 1,120 adolescents aged 14 to 17 years from three sites and two samples (550 detainees and 570 dropouts). Seven drug use outcomes and three violence outcomes were compared across sites. We found that site differences were dominant. Only two of 10 outcomes (cannabis onset and relative drug-related violence) were not significantly related to site as a main effect or through an interaction. The most common site differences showed that the Toronto samples reported higher rates of drug use than Philadelphia and Amsterdam. Our findings indicate that drug taking behavior transcends geopolitical boundaries and that there is no clear evidence that rates of drug use are related to policy climate.
