Brief Summary
Abuse of psychoactive substances is a behavior belonging to the field of risk behaviors that begins and takes place during adolescence. These risk behaviors are a major public health problem in France and worldwide. Cannabis is the first illicit drug consumed by adolescents in France. His experimentation progresses rapidly between 11 and 17 years. The relationship between cannabis use and mental health has been shown by several studies. In particular Attention Deficit Hyperactivity Disorder (ADHD), characterized by attention deficit, impulsivity and disabling motor hyperactivity and beginning before 12 years of age (DSM-5), is a major risk factor for the consumption of cannabis. ADHD is a common condition (9% of children and 5% of adults), but often undiagnosed or untreated. It has been shown that the treatment of ADHD in childhood protects the consumption of psychoactive products during adolescence or adulthood. However, to our knowledge there is no study showing that treatment with methylphenidate in an ADHD patient - not treated - but already a cannabis user, was a positive prognostic factor in the decrease in cannabis use.

Methylphenidate
EXPERIMENTALMethylphenidate delay shape, 10 and 30 mg capsules. Treatment should be started at a dose of 10 mg per day or 20 mg/d (depending on the weight of patients), with increasing weekly, according to the clinical tolerance, in order to get an effective dose on the symptoms of ADHD to S4, not more than 1 mg/kg/d (capped at 60 mg/d).
Matching Placebo
PLACEBO COMPARATORInterventions
Methylphenidate delay shape, 10 and 30 mg and matching Placebo capsules. Treatment should be started at a dose of 10 mg per day or 20 mg/d (depending on the weight of patients), with increasing weekly, according to the clinical tolerance, in order to get an effective dose on the symptoms of ADHD to S4, not more than 1 mg/kg/d (capped at 60 mg/d). This gradual dose treatment will be resumed in the same manner in M3 at the beginning of the phase in open, allowing the respect of the average of the ADHD support (no), without loss of chance for the Group at 3 months, because it is customary to discontinue treatment during holiday periods).
