How much do you smoke? how often and how much. I had a friend who needed to quit bud for awhile, And he was a really nasty SOB for about 2 weeks and after that he started to get better. Maybe you just need to cut down a little, let your tolerance drop, and then use weed to numb yourself again. Tbh, if weeds causing you to change then maybe you need to cut down quite abit? I love to smoke as much as the next man but i sure as shit would make changes if it was changing the way i think and react in a negative way. Maybe there's something else in you're life that's making you aggressive and your just being calmed down when you smoke and then when you down the other factor raises you into a agitated state?
