My son is adamant that marijuana helps his depression. I don't doubt it but I believe it causes more depression in the long run. He has tried to self medicate with Xanax in the past and said it made him forgetful. He won't go to the doctor for depression. He is almost 21 so I can't force him. I think there probably are some people who can function on marijuana (thought I believe it is wrong for a Christian standpoint) but my son is not one of them. He has really ruined his life, going on to other drugs, may or may not be on some of them. Does anyone have anything they know about this? Thank you.
