The Impact of Active Drug Use on Psychosis and Aggression Incidence Rates
This study examines the incidence rates of psychosis and aggression among individuals exposed to active drug use compared to unexposed individuals. It highlights a significant increase in psychosis incidence among active drug users at a rate of 13.0 per 1,000 person-years, with a rate ratio of 1.62. Additionally, aggression incidence rate was noted at 83.30 per 1,000 person-years, showing an increased risk with a rate ratio of 1.47. These findings underscore the association between active drug use and the heightened likelihood of experiencing psychotic symptoms and aggressive behavior.
