Abstract
When excessive cannabis consumption occurs in adolescence, the adverse consequences extend into adulthood. Interventions by GPs are effective in preventing harm associated with alcohol use. Similar interventions have potential in addressing cannabis use. To develop and pilot test a brief intervention targeting excessive cannabis use (defined as > or = 1x/week) in young people in primary care. Pilot intervention trial. Seven family practices in Switzerland. The team collaborated with GPs and young people to develop the intervention. Seven GPs piloted its use in their consultations. Patients aged 15 to 24 years consulting for any health problem were recruited before the consultation. Cannabis use, other substance use, and their psychosocial correlates were assessed with a short confidential questionnaire administered before the consultation and 1 month later. GPs, staff, and patients were asked to comment on the study and its feasibility. Of 81 young people invited to participate, 78 (70% female) agreed (participation rate: 96%). One in seven (13.2%, 95% confidence interval = 7.5% to 18.9%) used cannabis at least once a week. Data at 1 month were available for 42% who had provided email contact details and 91% of those who had provided their mobile phone number (63% overall). In most cases, the intervention lasted no more than 5 minutes. Comments from participants added favourable data towards the feasibility of the study. This pilot study provides a solid base on which to build a randomised trial of a brief intervention addressing cannabis use in young people consulting in family practice.

Summary
The adverse short- and long-term outcomes of excessive cannabis use are well documented.[1] When excessive cannabis use occurs at a vulnerable age such as adolescence, the physical, psychological and developmental consequences extend into adulthood.[2] Young people who use cannabis regularly have lower educational achievements, engage in more healthcompromising behaviours, suffer more accidental injuries and respiratory disorders, and have higher rates of mental disorder and cognitive impairment.[3,4,5,6,7] Regular use of cannabis during adolescence is associated with psychosocial maladjustment in later life, suggesting that it interferes with the developmental process of adolescence.[2,8] Weekly or more-frequent cannabis use in adolescence is related to a fivefold increase in the risk of dependence in adulthood.[9]. The prevalence of regular cannabis use is high. When excessive cannabis consumption occurs in adolescence, the adverse consequences extend into adulthood. Interventions by GPs are effective in preventing harm associated with alcohol use. Similar interventions have potential in addressing cannabis use
