Me and a close friend stopped smoking weed at the start of the year. Both of us were every day users since 16 - 18. We are now 31 and 32. Both of us have had long form discussions about marijuana and how it was affecting us since stopping use. I think the worst thing about marijuana, is its insidious. Alot of the problems its causing are so subtle and slow growing, you put it down to like personality faults lol. I literally thought I was an anti social piece of shit with a temper problem. Turns out I just had a drug problem that crept up on me without realising. Never been happier since quitting. 3 Months after stopping weed, i kicked ciggies too.
