Résumé : |
ENGLISH : The present study investigated characteristics of recreational drug users, especially ecstasy (MDMA) users, in 254 undergraduates. All participants completed a drug history questionnaire (DHQ), the impulsiveness venturesomeness and empathy questionnaire, a novel risk-taking task (Bets16), and 59 also completed the tri-dimensional personality questionnaire (TPQ). DHQ responses allocated participants to five groups: non-drug controls, cannabis users, polydrug (no ecstasy) users, low (20 occasions) ecstasy users. Eighteen percent of the sample had used ecstasy and of the ecstasy users, only one had not used other substances. A larger proportion of high ecstasy users had also used amphetamines, cocaine and LSD in comparison to the low ecstasy and non-ecstasy polydrug users. High ecstasy users typically took significantly more ecstasy tablets compared with low ecstasy users. Impulsiveness, venturesomeness and novelty seeking behaviour increased from the non-drug users to high ecstasy users. Ecstasy users (low and high) and polydrug (non-ecstasy) users had higher levels of impulsivity, venturesomeness and novelty seeking behaviour compared with non-drug users. Furthermore, high ecstasy users scored higher on the Bets16 risk-taking measure than non-drug users, cannabis users and low ecstasy users. The findings are discussed in relation to: (i) the possibility that increased impulsivity pre-dated drug use; and (ii) the possible link between impulsivity and the putative serotonergic neurotoxicity of ecstasy.
