The advice of Marcel Rofo
Marcel Rofo’s point of view, child psychiatrist
Is your grandson a regular consumer or an occasional consumer, who is content to smoke cannabis on Saturday evening in a recreational way? These are two very different cases. In the first, it is to be feared that it will be subject to an addiction which he can no longer detach himself. What about his schooling? Of his investment in studies or in his work? I miss elements to answer you well, Marie-Claire.
In any case, you have not done not to search in his business, which would have broken the great confidence that Titouan has shown you by admitting to smoking cannabis with his friends. It is important to preserve it. Also, do not repeat to his parents what he told you. The other advice I give you is to offer him to support him with a specialized consultation. If he agreed, you would make an appointment in an addictology center or, failing that, of young adult psychiatry in a medicopsychological center. Maybe Titouan will be grateful to you. We cannot exclude the hypothesis that his confidence is basically a call for help. You see, you are not helpless, Marie Claire: you have a role to play!
