Any regular substance use is substance abuse. Drink daily? You're an alcoholic ass. Smoke daily? You're a stoner dirtbag.
Pot, for me, is a deeply introspective drug, a lesser cousin to mushrooms. As a dirty hippie mate put it, sagely, it can leave you alone with what could be the best or worst thing ever: your self.
Used recreationally, it inspires apathy and lethargy. Used as something like a sacrament, it has a therapeutic utility. I'll smoke again, and I'll trip again, but neither will ever be at, like, a concert, or with 12 hours of video games. Our people's historic psychotropic use was not recreational as we understand recreation, as best I can figure.
Personally, once every few weeks, I get baked as Fuck, crank metal and go lift. The transformation in to a mouth-breathing uncommunicative autist crushing plates is church. Then I go home, shitshowershave, and put on daddy-face again, having been through something hard.
