My son is 18 next month. He has smoked weed for the last 2years. We have tried everything to help him stop but my husband was diagnosed with cancer last year so we have had a lot to cope with. He smokes daily and it has been so hard. He had told me today that he has made an appointment with his GP to help but it’s not for another few weeks. We have private heath care, who should I try and get help with? He believes he made need treatment for anxiety/adhd.
