This study was designed to evaluate synthetic cannabinoid (SC)-induced psychotic disorders in terms of their structure and clinical characteristics among hospitalized patients in Russia. It was a longitudinal, observational cohort study which included a total of 46 male patients who underwent the inpatient treatment in the intensive care unit or emergency department due to the SC-induced psychoses. Data on sociodemographic and disease-related characteristics, psychometric assessment scales obtained in face-to-face interviews, were recorded in all patients. The duration of catamnestic follow-up period was 2 years, with the major focus on manifestation of the schizophrenic process. Mean (SD) age of the patients with psychotic disorders induced by the SC use was 23.2 (3.5) years. Among 46 patients, 29 (63%) were SC-dependent and 17 (37%) were diagnosed with SC abuse. Average age at onset was 16.4 for psychoactive substances and 19.7 years for SC use. Marijuana was the most common first used substance. Based on our observations, we identified four clinical variants of the SC-induced psychoses. Our findings revealed that psychotic disorders are typical for the SC intoxication and most commonly influence young adults. Based on our observations, we identified four clinical variants of the SC-induced psychoses and revealed the signs which may indicate them. This study emphasizes the role of appropriate psychiatric management of SC-induced psychoses, since often only catamnestic long-term follow-up enables clinicians to determine the correct diagnosis and reveal the manifestation of the schizophrenic process.
