Ds is 16 and is addicted to cannabis. He has violent mood swings that has meant that we had to call the police out when he became aggressive . It has changed our son from a sensitive and kind young man into a someone we don’t recognise. We don’t give him money but he has a part time job. He was very bright and went to a selective school but the last year he has lost all interest in college work and barely attends. We are now receiving advice from social services but he won’t engage with any outside help. I’m so desperate to turn his life around but I feel powerless. He has a younger sister and I know this is having a massive negative impact on her life too.I have spoken to his friends parents but although they all know they are smoking weed it hasn’t impacted their lives the same and so they don’t see it as a problem just something that a lot of teens do. I’m so worried that he will have schizophrenia in the future from the amount he is smoking . We try so hard every weekend do think of things to do as a family but he refuses to do anything. We have promised him driving lessons if he stops but he is too addicted
