im 18, in college.
smoking tobacco: I don't mind cigars and hookah, because they're not very addictive and don't have HIDDEN additives. I don't smoke those much at all.
I don't mind clove cigs (i don't smoke them), because the people that i know who smoke them aren't habitual smokers. However, regular cigs smell like shit and people smoke them way too much. They also kill you, so i dont really like that.
weed: Medicine. Has helped my depression, anxiety and is fun, so fuck off. It also isn't addictive. I've stopped smoking weed for months on end without a second thought, so fuck off. (fuck off=to the feds)
anything else
salvia: trippy shit, i dont care if anyone does it, as long as it's not more than once a week it's legit. I havent done it since i was 16
crack/meth: ew.
