Overview
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.

Outcomes
Primary Outcomes

Number of participants that use several cannabis products (hashish, marijuana, etc.)
Tobacco use
Time Frame: Change between baseline and 6 weeks follow-up
Number of participants that use several type of tobacco product/s
Abstinence from cannabis
Time Frame: Change between baseline and 6 weeks follow-up
If a participant reduces or quits their cannabis use, we will ask for their presence of 16 withdrawal symptoms. Each symptom is scored from 0 (minimum) to 3 (maximum). Higher scores mean a worse outcome.
Abstinence from tobacco
Time Frame: Change between baseline and 6 weeks follow-up
If a participant reduces or quits their tobacco use, we will ask for their presence of 6 withdrawal symptoms using the Fagerström test. The test has a minimum score of 0 and a maximum of 10. Higher scores mean a worse outcome.
