Annual incidence of cannabis-induced psychosis, other substance-induced psychoses and dually diagnosed schizophrenia and cannabis use disorder in Denmark from 1994 to 2016

Carsten Hjorthoj et al.

Summary: The study indicates that the incidence rate of cannabis-induced psychosis is increasing year by year, which is related to the increase in THC content and cannabis use. Dual diagnosis (schizophrenia and cannabis use disorder) is also on the rise, while the incidence rate of alcohol-induced psychosis is decreasing. There is no significant trend in the incidence of psychosis induced by other substances.
