Cannabis is the illicit drug most widely available in Europe. In most European countries, cannabis use increased during the 1990s and early 2000s. France belongs to the highest-prevalence countries, with a lifetime prevalence of 30.6 % and a last year prevalence of 8.6 %. Trends of consumption across the life course and over time are well known, but to date no study aimed at analyzing cohort effects. This project uses a series of surveys which provides a unique opportunity to analyze lifetime and last year cannabis use across the life course and over time, for various cohorts. First, descriptive statistics are derived from pseudo-cohort analysis. Then cross-classified random effects models are applied to disentangle age, period and cohort effects.
