Brief Summary

Aims: To characterize the pattern of cannabis and tobacco use and withdrawal symptoms in people who start treatment for cannabis use disorders (exclusive cannabis, concurrent and/or simultaneous with various tobacco products) through an aplication game and considering the type of users. Methodology: Mixed-methods research composed of three studies. Study I: qualitative participatory action study aimed at exploring the experiences and preferences of the cannabis users on the use of apps. This information will be instrumental in the co-design of the app. Study II: prospective longitudinal study aimed to establish consumption patterns and transitions between substances and to validate the scale of cannabis withdrawal symptoms in the Spanish population. Sample size: expected RR=1.20, α =0.05, β= 0.20, losses= 20% (n=282). Study III: qualitative study to explore participants' experiences during the process of quitting cannabis and / or tobacco. Expected results: Characterization and prediction of variables that influence cannabis and tobacco cessation/ reduction and describe withdrawal symptoms according to consumption patterns with aim of improving the design of future interventions.
