I shouldn't be shocked, but I am:
The objectives of the present study were to identify the prevalence of alcohol abuse and marijuana use among First Nations youth living on-reserve, and to identify independent risk indicators associated with these behaviours. Two hundred four students from the Saskatoon Tribal Council (Saskatchewan) who were enrolled in grades 5 through 8 were asked to complete a school health survey. The prevalence of alcohol abuse and marijuana use among First Nations on-reserve youth was 23.5% and 14.7%, respectively. Surprisingly, female First Nations youth were more likely to abuse alcohol and use marijuana than male First Nations youth. The prevalence of alcohol abuse and marijuana use among Saskatoon urban youth of the same age were only 5.4% and 2.7%, respectively. After regression analysis, five independent risk indicators were associated with alcohol abuse and marijuana use among First Nations on-reserve youth. The prevalence of alcohol abuse among First Nations on-reserve youth is higher than that in neighbouring urban youth of the same age.
