My son is a freshman in College and after seeing his spring grades today I hit the roof. I have been on him about his dope smoking for a while and he refuses to stop. Not sure about other states but here in California weed is very legal and most of the kids have medical marijuana cards so it is basically legal. So all I hear is "everyone does it, " you just dont understand" etc... He says that it helps him wind down and get to sleep, reduce anxiety, nail biting. etc. I know that all of his friends smoke, and most of their interactions all involve smoking dope. Although he has been in a little bit of trouble he is a good kid and does not have any behavioral issues. Has a part time job and is an all around good young man. He was diagnosed with ADHD at 13 and was on Adderall for a few years but grew tired of it and hasnt taken it for a while. He seems to have grown out of the HD part but the AD part is still there. Even though it is technically legal I am against it and know first hand what it can lead to. I am also concerned it is hurting his studies. Today I threatened to kick him out of the house and take away his car if he didnt stop and told me I was being ridiculous. Am I over reacting?
