Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The researchers are hoping to recruit 303 participants for this study from Central and Eastern Canada. Participants will be randomly assigned to one of the treatment groups (i.e., CBT with MET, CBT without MET) or the psychoeducational control group. Individuals in either treatment group will be given 6 weeks to work through 8 online modules. Throughout the modules, participants will identify goals related to cannabis use, learn strategies to cope with cannabis cravings, triggers, and social pressures and learn to prevent relapse. Participants randomly assigned to the control (i.e., psychoeducation) will receive links to websites that provide general psychoeducation about cannabis use and wellbeing. All participants will complete online assessment measures at baseline, end of treatment, and at follow up approximately one month later (i.e., 0 weeks, 6 weeks, 10 weeks) in order to assess the efficacy of the treatment. At the end of the study, individuals in the control group will be given access to the CBT without MET treatment.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CBT with MET treatment group
Participants in this arm will be provided with an MET-therapist guided introduction, in addition to the online CBT treatment.
Online CBT with MET treatment
The CBT with MET treatment condition will begin with an MET-therapist guided introduction to the program and first module. After this guided introduction, they will have access to the remaining 7 treatment modules and have 6 weeks to complete them. The content of all modules is derived from Cognitive Behavioural Therapy and Motivational Interviewing. Through module engagement, participants will identify goals related to cannabis use, learn strategies to cope with cravings, triggers, and social pressures, and learn to how prevent relapse. Participants will work through modules sequentially.
CBT without MET treatment group
Participants in this arm will be provided with a brief non-MET research assistant-led welcome to the program, in addition to the online CBT treatment.
CBT without MET treatment
The CBT without MET treatment condition will begin with a brief non-MET trained research assistant welcome to the program, and will not include working through the first module together. After this welcome, they will have access to the 8 treatment modules and have 6 weeks to complete them. The content of all modules is derived from Cognitive Behavioural Therapy and Motivational Interviewing. Through module engagement, participants will identify goals related to cannabis use, learn strategies to cope with cravings, triggers, and social pressures, and learn to how prevent relapse. Participants will work through modules sequentially.
Psychoeducation (Control)
The control group will be provided with psychoeducational resources about cannabis and wellbeing.
