Background: While substance abuse among psychiatric patients is a widely known problem in clinical practice, there is no local study about prevalence and co-occurrence of substance abuse in north of Iran. Objectives: The present study was designed to determine the frequency of smoking, alcohol, opioid and cannabinoid substances, and prescription medicines abuse or dependence among Psychiatric Inpatients. Patients and Methods: A cross-sectional 2-year case register study was conducted on all (n = 492) psychiatric inpatients of Zare Psychiatric Hospital in Sari located in north of Iran. The data were obtained by using a standardized and validated questionnaire that contained demographic information along with information on co-morbid psychiatric problems and alcohol, cannabinoids, opioids, and cigarette usage. Results: The mean (± SD) age of samples was 39.9 (± 11.9) years and male:female ratio was 3.6. Opium with or without using other illicit substances was the most frequently abused substance (67). Significant association were found between illicit substance abuse and demographic variables of male gender, a low level of literacy, living in the urban area, unemployment, cigarette smoking, and young age. There were statistically significant association between schizophrenia and substance abuse (P < 0.001). Conclusion: High prevalence of dual diagnosis warrants attention to the management of substance misuse while treating mental disorders, and should be incorporated in the holistic treatment plan of psychiatric inpatients. © 2015, Mazandaran University of Medical Sciences
