A Mobile App to Reduce and/or Quit Cannabis Use
Sponsor: Alba González-Roz, PhD
Summary
This study aims to develop an App-based intervention (CANQUIT) aimed at regular cannabis users. The efficacy of this intervention will be evaluated in the short-term (1-month follow-up) and long-term (3- and 6-months follow-ups) using a sample of 120 participants. Participants will be randomly assigned to the experimental arm (App-assisted CBT-based intervention) or the control (App-assisted self-help guide). The study will also estimate the economic impact of the intervention by considering the benefit-cost ratio (BCR) and net benefit (in €) associated with the total cost of the program. The goal is to provide evidence that can inform policy decisions regarding cannabis use and minimize the negative consequences on the physical and mental health of young adults in Spain. This study aims to offer a cost-effective prevention strategy that minimize the negative consequences on the physical and mental health of young adults in Spain.
