Adolescent cannabis use and psychological distress from 2013 to 2023: A population‐based study in Ontario, Canada

Abstract Background and aims: Epidemiologic research suggests that adolescent cannabis use is associated with psychological distress (i.e. depression and anxiety symptoms); however, most studies have relied on 20th‐century data, when cannabis was significantly less potent than today. This study aimed to estimate the association between adolescent cannabis use and psychological distress using contemporary population‐based data and examine the roles of time [as a proxy for increasing Δ9‐tetrahydrocannabinol (THC) potency], sex and age of initiation. Design: Representative cross‐sectional survey conducted biennially
