Impulsivity and substance-related outcomes share a complex relationship, as various facets of impulsivity exhibit distinct associations with different drug-related outcomes. This study examines the associations between frequency and quantity of alcohol and marijuana use with impulsivity traits, psychological distress, and the utilization of emotion regulation strategies. A survey asked Argentinian citizens (n = 1507, 356 men) about frequency and quantity of alcohol or marijuana use on each day of a typical week, as well as anxiety, stress, and depression symptoms (DASS-21), impulsivity-like traits (UPPS-P), and emotion regulation strategies (ERQ). The 2-month prevalence of alcohol or marijuana use was 80.1%, and 27.2%, respectively. Premeditation was significantly (p < 0.05) and negatively associated with both frequency and quantity of alcohol consumed, whereas negative and positive urgency were positively and significantly (p < 0.05) associated with quantity of alcohol or marijuana use, respectively. Greater depression symptoms predicted greater quantity of alcohol use, whereas lower emotional suppression or lower cognitive reappraisal were significantly (p < 0.05) associated with a greater frequency of alcohol or marijuana use. Sensation seeking was significantly (p < 0.05) and positively associated with frequency of marijuana use. Individuals with higher levels of impulsivity-like traits, higher levels of depression, or lower use of emotional regulation abilities appeared to be at a higher risk of alcohol or marijuana use. In this sample, the use of alcohol (though not marijuana) seems to fit a negative reinforcement pathway. The study suggests that individuals with risk factors for drug misuse could benefit from interventions aimed at enhancing emotion regulation.
