Cannabis and alcohol use, affect and impulsivity in psychiatric out-patients' daily lives.

ABSTRACT:

Background and aims

Cannabis and alcohol are the most commonly used (il)licit drugs world-wide. We compared the effects of cannabis and alcohol use on within-person changes in impulsivity, hostility and positive affect at the momentary and daily levels, as they occurred in daily life.

Design

Observational study involving ecological momentary assessments collected via electronic diaries six random times a day for 28 consecutive days.

Setting

Out-patients' everyday life contexts in Columbia, MO, USA.

Participants

Ninety-three adult psychiatric out-patients (85% female; mean = 30.9 years old) with borderline personality or depressive disorders, who reported using only cannabis (n = 3), only alcohol (n = 58) or both (n = 32) at least once during the study period.
