In both groups, more than 50% have anxiety and depression; over 25% have associated somatic disorders and digestive diseases, respiratory, pain is the most common. Almost 99% use oral route; nearly 100% have a daily consumption and about 20% of the alcohol concomitantly; 24% of HDB use benzodiazepines and 18% of the methadone group (P=0.06); 33% of the population using methadone consume illicit psychoactive substances and 21% for HDB population (P<0.0001), in particular cannabis (P<0.0001). Heroin and cocaine are also consumed.
