Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study examined a community based cannabis cessation program in Norway (CCP). The CCP uses a combination of cognitive therapy and psychoeducation and covers the normal withdrawal period for cannabis smoking cessation (up to 8 weeks), comprising \~15 individual sessions. From 2005 onwards, the CCP was implemented as a low-threshold community-based program in several Norwegian municipalities, e.g., Kristiansand, Fredrikstad and Oslo. The study had an observational one-group pre- / post test design. Outcomes was changes in cannabis use, mental distress, well-being, social network and sense of coherence (SoC) measured post-intervention (T2) and at a 3 months follow-up (T3).

Cannabis cessation Program

Intervention Type BEHAVIORAL

Lundqvist and Ericsson developed the 'Cannabis Cessation Program' (CCP, Nordic abbreviation: HAP) in Sweden in the 1990s. The method uses a combination of cognitive therapy and psychoeducation and covers the normal withdrawal period for cannabis smoking cessation (up to 8 weeks), comprising \~15 individual sessions. It describes a medical, a psychological, and a social phase, in which the participant is helped to recognize and address typical problems related to each phase, e.g., physical and psychological withdrawal problems. The overarching aim of the program is to help cannabis users to reorganize thinking patterns that developed while they were using cannabis and increase their social and psychological coping skills in relation to quitting cannabis use. The CCP manual has been translated into eight languages, e.g., Norwegian.
