Prevalence of substance involvement in our sample was broadly in line with rates reported previously in another UK-based sample, ESPAD [9], of 15–16-year-olds. ESPAD reported rates of life-time use of alcohol at 91%, with 68% having been drunk in the last year. In our sample for the same age group the rates were 91% and 57%, respectively. For life-time cigarette use and marijuana use ESPAD reported prevalence rates of 58% and 35%, while we found rates of 50% and 24% for the same age group.
