A sample of 252 drug-addicted patients who sought treatment was assessed. Information on violent behaviours, criminal acts, socio-demographic factors, consumption factors, psychopathological factors and personality variables was collected. The sample was divided into four groups according to the presence of violence and/or criminal behaviours. There were significant differences between the groups on some variables. In general, patients associated with both violence and criminal behaviours showed a greater severity in drug consumption and maladjustment variables, as well as a higher rate of treatment dropout and re-entry.application/pdfengDrug addictionViolent behaviourCrimeComorbidityDropoutinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
