What this trial studies

This study evaluates the efficacy and cost-effectiveness of a mobile app-based intervention called CANQUIT, designed for regular cannabis users aged 18-30. Participants will be randomly assigned to either an experimental group receiving a cognitive-behavioral therapy (CBT)-based intervention or a control group using a self-help guide. The intervention lasts four weeks and includes psychoeducation, emotion regulation training, and relapse prevention strategies. The study aims to assess both short-term and long-term outcomes, as well as the economic impact of the intervention in Spain.
