Sounds like they were all lightweights and go TOO high. I've never had a 'bad high' really, cause I can tolerate it. But I know one of my friends has gotten more high than he would have liked to be on 2 occasions.

Yeah, I'm pretty sure thats exactly what happened. Sounds like your buddy "whitey'd" too, or came close. So yeah, your weed didn't "expire" (as if it could) you and your buddies are just light weights.
