Joint Effort App for Cannabis Use
(JOINTEFFORT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a mobile app called Joint Effort, designed to help young adults use cannabis more safely. The app provides personalized feedback and guidance, increasing users' awareness of their cannabis habits and helping them make informed decisions. Participants will either use the app or receive brief feedback and standard information about cannabis use. The trial seeks French-speaking individuals aged 18-35 who have used cannabis in the past month and own an iPhone. As an unphased trial, this study offers a unique opportunity to contribute to research that could enhance cannabis safety for young adults.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that the Joint Effort mobile application is safe for users?
Research shows that the Joint Effort app helps people manage their cannabis use safely. Testing has ensured its ease of use and effectiveness. Studies have found that apps like Joint Effort can help people reduce cannabis use and make better decisions about it. No reports of safety issues or harmful effects have emerged from using the app. As a mobile app, it doesn't carry the same risks as trying a new medication. Instead, it provides users with information and support to make better choices about cannabis use.12345
Why are researchers excited about this trial?
Researchers are excited about the Joint Effort app because it takes a fresh approach to helping young adults manage their cannabis use. Unlike traditional methods that might involve counseling or medication, this app leverages technology to enhance awareness and decision-making through personalized feedback and persuasive communication. It’s based on the Theory of Planned Behaviour, which targets intention, attitude, and perceived behavioral control, offering a more tailored and interactive experience. Additionally, the optional logbook feature allows users to track their own cannabis use, making it easier to monitor progress and stay motivated.
What evidence suggests that the Joint Effort app is effective for safe cannabis use?
Research shows that the Joint Effort mobile app, a treatment in this trial, might help people better manage their cannabis use. The app offers personalized feedback and helps users track their cannabis habits, encouraging change. Studies have found that smartphone tools can help young people reduce cannabis use. Previous users found the app helpful and easy to use, suggesting it could support safe cannabis use. While the results are promising, further research is needed to confirm these findings. Another treatment arm in this trial provides brief normative feedback and standard information, serving as an active comparator.12367

Active Control
The Joint Effort mobile application aims to support young adults in taking action on their cannabis use. Based on the Theory of Planned Behaviour, the content focuses on intention, attitude, and perceived behavioral control. Various intervention methods and strategies are used to address these determinants (e.g., personalized feedback, persuasive communication, self-observation, and activation of intention). The objectives include: to allow the individual to become aware (or more aware) of their cannabis use, to support the individual's decision-making process of taking action on their cannabis use, and to guide and support the establishment and sustainability of an action plan. An optional logbook-type feature (weekly journal of cannabis use) allows personalized monitoring and data collection throughout the course of the intervention.
The comparator is composed of a brief normative feedback regarding last month's frequency of cannabis use and basic reliable non-personalized information on lower-risk cannabis use (official public websites).
