Childhood events as factors in continued cannabis use in adulthood: a longitudinal study of a 30-year follow-up cohort.

ABSTRACT:

Background

Cannabis use patterns have evolved over time, with increasing persistence into adulthood. This study aims to identify cannabis use trajectories from adolescence to adulthood and to examine the influence of early individual and family factors on these trajectories.

Methods

This study included 622 participants from the French TEMPO cohort who reported cannabis use between 1999 and 2021, based on 14 measurements points.
