Comparisons of Alcohol and Cannabis Use by Youth in the Netherlands, US, and Canada

"Results—Laws regarding alcohol and cannabis were found to be strictest in the United States, somewhat less strict in Canada, and least strict in the Netherlands. On most measures of drinking, rates were lower in the United States than in Canada or the Netherlands. With United States as the referent, relative risks (RR) for monthly drinking were 1.30 (1.11–1.53) for Canadian boys and 1.55 (1.31–1.83) for girls, and 2.0 (1.73–2.31) for Dutch boys and 1.92 (1.62–2.27) for Dutch girls. Drunkenness was also higher among Canadian boys and girls and Dutch boys. However, rates of cannabis use did not differ between the countries, except that Dutch girls were less likely to use cannabis in the past year (RR= .67; 0.46–0.96)."
