Background: Cannabis is the most prevalent illegal drug used in France, and consequences
arising from the step of 'casual consumers'(1-10 joints/month). Side effects of cannabis
are now well documented: Trauma (driving after consuming cannabis), respiratory,
cardiovascular diseases and psychiatric and social problems. The general practitioner
(GP) is the health professional most viewed by adolescents. Brief interventions (BI) for
adult alcohol use have been shown to be efficient. Some BI have been designed to inspect
adolescents and consumption of cannabis have been piloted, showing their feasibility, but
no test has validated them.
Aim : Does a BI conducted by general practitioners reduce consumption of canabis in 15 to
19 years old ?
Method:
Two preliminary qualitative studies (with adolescents and GP), were used to analyze the
difficulties of communication around cannabis use. The Scientific Committee has analyzed
the results and developed a workshop around BI, adapted to adolescents cannabis users.
CANABIC is a quantitative study to validate use of BI with cannabis users: a randomized
controlled trial, clustered study, comparing an intervention group (IG) and a control
group (CG). The intervention is the achievement of the IB during a specific consultation.
The outcome is the consumption of cannabic (Number of joints / month).
The study will be carried out in 3 french regions : Auvergne, Rhône-Alpes and
Languedoc-Roussillon. 150 GPs wil be recruited and randomized in intervention group or
control group (ratio 1 :1).
Each GP will inlcude 5 adolescents (i.e. a total of 750 adolescents) - . The number of
adolescents needed has been calculate with hypothesis of a significant difference of 30%
in consumption of cannabis between adolescents who beneficied of BI (IG) and those who do
not experienced BI ( CG) A pilot study has been conducted. Cannabis use by adolescents
has decreased. Their perception of cannabis has changed: they are aware of the harmful
effects of their consumption. This pilot study has improve many points of the protocol.
Results:
A decrease of 30% of consumption is expected (joints per month). Perception of cannabis
by adolescents will be reviewed.
Conclusions:
To validate an IB adaptated to consultation with adolscents cannabis consumer in order to
provide a tool for GP in their daily practice.
