Adult Psychiatric, Substance, and Functional Outcomes of Different Definitions of Early Cannabis Use.

ABSTRACT:

Objective

Research on associations of early cannabis use with adult functioning reports mixed findings. This may be due, in part, to wide variations in the definitions of early cannabis use. This study aims to compare associations of 4 commonly used definitions of early cannabis use-related to timing, dose, duration, and associated symptoms-with adult outcomes.

Method

Analyses were based on a 20⁺-year longitudinal, community-representative study of 1,420 participants. Between ages 9 and 21 years (8,806 observations), participants were assessed for cannabis use and DSM-5 cannabis use disorder. In early adulthood (ages 24-26 and 30; 2,424 observations of 1,266 subjects), participants were also assessed for psychiatric, substance use, and functional outcomes.
