[Creativity in cannabis-users and in drug addicts in maintenance treatment and in rehabilitation].

The main aim of this study was to investigate potential differences between different groups of drug addicts (patients in maintenance treatment, n = 14; patients in rehabilitation, n = 12) and Cannabis-Users (n = 13), along with a healthy control group (n = 18), with respect to verbal and figural creativity and general cognitive ability. Participants worked on different measures for the assessment of different facets of creativity, intelligence and experienced psychiatric symptoms. The results indicated that patients in maintenance and, to some extent Cannabis-Users scored higher regarding verbal creativity than patients in rehabilitation. With respect to figural creativity we observed no differences between the experimental groups. Concerning the Big Five personality traits, patients in maintenance treatment scored highest on Neuroticism while on a purely descriptive level Cannabis-Users achieved the highest scores with respect to openness to experience and extraversion.
