Project Main Description: 

Most individuals with cannabis use disorder do not seek treatment, and this is often due to problems with accessibility and concerns about privacy. Web-based therapy addresses these two major barriers to treatment uptake.

To evaluate the efficacy of a web-based cognitive behavioural therapy (CBT) intervention in treating cannabis use and related problems.

Design and Method: 

This study is a two-group randomised controlled trial involving 200 participants. Participants assigned to the control condition will be sent a link to an educational resource relating to cannabis use. Participants assigned to the experimental condition will be sent a link to the intervention website, which will contain six CBT modules, assessments with feedback, and several optional extras. Between-groups comparisons will be conducted at post intervention and at a three-month follow-up. Primary outcome variables will be cannabis use, abuse, and dependence.


230 participants have been recruited for the research.  Final data will be available in August 2011.
