    There is little consensus regarding the prevalence of methamphetamine-induced psychotic disorder (MIPD). A search of the literature was performed, effect size estimates were calculated with event rates and were aggregated with a random-effects model. Seventeen studies were included in the meta-analysis, resulting in a composite event rate of 36.5%. The event rate of MIPD was significantly higher when the period of assessment was lifetime (42.7%) and when only individuals with methamphetamine use disorders (MUD) (43.3%) were included. The prevalence of MIPD in the reviewed studies is elevated. These results highlight the need for detection and prevention strategies, and population studies.
