I smoked lot of weed in the last 20 years. I used to smoke to feel better since i been having Social Anxiety most of my life. I recently stopped because i noticed smoking lot is what gave me anxiety on top a few other triggers.
For lot of people it won't harm them and simply make them feel better on a daily basis. For me it was quite the opposite. I guess if i started to smoke a little here and there it'd be better but i'm someone who's all in in everything i do and don't have middle ground :s
