In other random news, I accidentally smoked crack a few years ago, it was the weirdest feeling ever.
These guys were smoking something out of a can, and I was teetering on black out drunk, so I stumbled over, saw what I thought was charred black weed on top of the can, and drunkenly said "give me some!!". They were like "Are you sure, man?", and I insisted.
Unlike weed, which takes a couple of seconds to hit you, this hit just threw me back immediately and the room went white for a few seconds. It was a pretty incredible experience, but only lasted like ten minutes, then the ride was over and I went back to feeling stupidly drunk.
