Earlier quoted context omitted.
Are you implying that marijuana is "not harmful" and "can improve your quality of life"?
It improves my quality of life. I use it daily to keep my anxiety down. I do not use it during work. I am a productive and happy person! But just like any substance, it can be abused. Thank goodness I do not drink alcohol anymore though. That stuff ruined me. It's a depressant which just made my anxiety and depression worse and almost ended my marriage.
Although it'd be nice to not need anything, but it helps so much with anxiety (and other stuff).
