Is this trial a fit for you?

Probably not a fit

Patients currently engaged in substance use treatment or with severe substance use disorders may not benefit from this intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to compare two brief interventions designed for emerging adults aged 18-25 who exhibit potentially problematic cannabis use. Participants will undergo a detailed cannabis assessment and then be randomly assigned to one of the two interventions, each consisting of two sessions lasting 40-50 minutes, separated by one week. Follow-up assessments will occur immediately after the second session and at one and three months post-intervention, with salivary samples collected to measure THC and CBD levels. The study seeks to evaluate the feasibility, acceptability, and preliminary efficacy of these interventions.

Why it matters

Potential benefit: If successful, this intervention could help reduce problematic cannabis use among emerging adults, leading to improved health and social outcomes.

How similar studies have gone: While several cannabis brief interventions have been tested, their efficacy for emerging adults has been mixed, indicating a need for novel approaches like this one.
