The TRICCHOME application (TRajectoires Individuelles de Consommation de Cannabis en situation Habituelle et Observation de leurs Modalités en contexte Écologique) was developed to assess in real time cannabis use patterns of people aged 18 to 24, enabling them to detail what they choose to use, how they consume it and in what context. The application allows users to record their impressions of their consumption experiences, as well as providing information on certain health parameters and lifestyle habits (e.g., screen time, eating habits, physical activity, sleep). This application’s functionalities also make it possible to create a complete and detailed inventory of products used, from diluted oils and capsules to dabs and vapes. A “Statistics” section also enables users to track their own consumption, including retrospective data on quantities consumed, resulting effects, products most frequently used and most common habits.
