Psychedelic symptoms of cannabis and cocaine use as a function of trait impulsivity

Journal of Psychopharmacology January 8, 2015 JHP van Wel, DB Spronk, Kim P. C. Kuypers et al. 23 citations

Regular drug users with normal or high trait impulsivity levels showed largely similar subjective responses to cocaine, cannabis, and placebo. Cannabis increased dissociation, psychedelic symptoms, fatigue, confusion, depression, and anxiety while decreasing arousal, positive mood, vigor, friendliness, and elation. Cocaine increased dissociation, psychedelic symptoms, vigor, friendliness, elation, positive mood, anxiety, and arousal while decreasing fatigue. Only a few subjective measures differed by impulsivity level; psychedelic symptoms were most intense in high-impulsivity subjects. Trait impulsivity correlated negatively with vigor (r = -.197) and positively with loss of thought control (r = .237) during cannabis intoxication, but a broad association between trait impulsivity and psychedelic drug experience was absent.
