[Pathological gambling and addiction to cannabis: common psychosocial profile?].

Addiction can involve substances (heroin, cannabis, cocaine) or be characterised by behaviour (pathological gambling, addiction to sport, etc.). The question is to establish whether or not there is a specific personality profile (character, temperament) and emotional functioning (anxiety, depression, alexithymia) in subjects presenting addictive behaviour with and without substance use. To find some answers, a team from Sainte-Marguerite General Hospital in Marseille carried out a study comparing a group of cannabis addicts and a group of pathological gamblers.
