I'd try and fuck the sorority girl. That way her smoking your shit is a little more tolerable, and at least you'd be getting something out of it. I haven't heard her voice, but I can't imagine I'd mind unless she was super annoying.
go out and booze more, you'll meet some muddafuckers along the way, but you'll eventually find some kids who meet your standards of a chill group to blaze/chill wit
Don't sell your soul and just start drinking man, terrible habit.(just my opinion no need for flame thank you) Maybe just wear a legalize it bracelet, bob marley shirt, or even the line of LRG(lifted research group) brand clothing. Whenever I see someone wearing LRG I think right away "toker". It's legit because it makes it obvious to another head you blaze and yet it's not blatantly obvious like a budleaf or something.
Seriously? College is where many people really start smoking a lot. My school is like fucking weed central. I love walking around town and just catching random whiffs of people smoking. I can't even go out on a weekend night without getting offered bud by someone on the street. Ditto on the whole "don't start drinking" thing. Anyone I know that has gotten kicked out was drinking at least three nights a week. Does your school have a chapter of Students for sensible drug policy? They're always down to smoke, tons of hipsters in that organization though.
