The cost comes with abuse and that goes with anything, it could be beer, pringles and even food. I’ve consumed in moderation for 20 years and not on a daily basis and honestly I have nothing to regret and I doubt I ever will. There’s more damage done to my body from sitting down on a chair starring at a screen for 8 hours a day than the ocassional mj puff. Quite on the contrary, it has made me a lot more productive in moments when I was stuck and lifted the vail of the mundane conformity in thinking, enough to make me aware where I am too complacent and help me shake it off.
