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.

However, 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.
Hypothesis: The hypothesis of this study is that patients diagnosed with ADHD and cannabis-treated patients treated with methylphenidate will decrease their number of days of cannabis use compared to ADHD patients receiving placebo.
Originality and Innovative There is no study showing that treatment with methylphenidate in an ADHD patient - not treated - but already a problematic cannabis user, was a positive prognostic factor in decreasing cannabis use.
Moreover, there is not enough team in addiction trained in the detection of attention deficit disorder which is now recognized as a factor of vulnerability for the development of addictions. This project is the opportunity for a training in the detection of the ADHD in the adolescent and the young adult of the professionals of the addiction and the setting up of a treatment by Methylphenidate as well as its handling.
