ClinConnect Summary

This clinical trial is studying how young adults aged 18 to 24 use cannabis (marijuana) in their everyday lives. Researchers want to learn about different patterns of cannabis use—like how often people use it, the types of products they choose, and the amounts of active ingredients they consume—over a two-year period. The goal is to better understand how these use patterns might relate to social and health outcomes for regular or daily users.

To take part, you need to be between 18 and 24 years old, have used cannabis at least once a week in the past three months, be able to read and speak English or French, have access to a mobile phone, and be willing to follow the study’s instructions. People who are currently in treatment for cannabis problems, using cannabis for medical reasons, or involved in other cannabis-related studies cannot join. Participants will be asked to share information about their cannabis use over time, helping researchers track changes and gather useful insights. This study is not yet recruiting, but it aims to better understand young adults’ cannabis habits to support healthier choices in the future.
