Summary

This pilot study tested a mobile app called iCanChange in 100 young adults (ages 18-35) with psychosis and cannabis use disorder. The app uses motivational interviewing and cognitive behavioral therapy techniques through short interactive modules. The main goal was to see if the app is acceptable and feasible to use, not whether it actually reduces cannabis use.
