I've known several people to throw up after smoking too much. It's ususally because they've ate too much, but it's also been people who don't smoke often trying to keep up with people who smoke every day. I know that it's hard to pass the J and not look like a puss, but if you can't handle it, then pass and don't make me clean up puke. I think more of someone who knows when they're high enough to pass then someone who has to smoke a whole bag to "look cool".
