Randycaver's thoughts on this are totally valid. Before I get into anything, here's an analogy. It's kind of weird, so bear with me.
Say you like hamburgers. When most people want a hamburger, they go to a fast food place. They're on every block, pretty cheap, and a lot of people like it. Say you like hamburgers, but not the kind from fast food places. If you want a burger, you're going to have to drive to an actual restaurant or something close to it, and pay a couple bucks more. All day, you're around people who are like, dude, you should just go for the cheaper burger at McDonald's.
(If you're really confused at this point, the burgers represent drugs, the restaurants represent drug dealers, and fast food represents marijuana. And the reference to driving is something about, I dunno, love.)
Personally, there's nothing wrong with pot, or people who smoke it. It's one of the more benign drugs, etc., etc., etc,.
See, the problem is pot culture. This isn't saying that going down to a head shop to buy a handblown glass pipe from another stoner is a bad thing.
The problem is when you start living up to a stereotype. It's when smoking pot becomes part of your identity. If you smoke pot, great. If you smoke pot and do something which dispells the idea of pot smokers being lazy and apathetic, that's even better. What bugs me is when people try too hard to be a stoner - feeling the need to announce this to the whole world.
People do this. They'll think I'll be impressed that they're selling weed, or getting high everyday. I don't smoke pot, and it doens't really bother me if people do. It just gets annoying when people constantly mention the fact they get high.
