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.
