Club Drugs and Psychiatric Sequelae: An Issue of Vulnerability and Previous Psychiatric History.

The pursuit of pleasure among clubbers and disco-goers often involves drug use. However, whether substance use may represent a relevant risk factor contributing to the development of psychiatric symptoms and of mental illness remains debated. The purposes of this study were to evaluate the percentage of subjects who developed long-lasting psychiatric symptoms in a sample of subjects reporting use of substances in nightclubs, and to evaluate the role of a previous psychiatric diagnosis in these subjects.
