ditto. My experiences back the 70s, however, didn't involve agression...mostly talking to people that weren't there, or getting lost in the bathroom. Had one friend of mine get punched in the face while 'taned, and he spent an hour or two trying to figure out whether it had really happened. Can't imagine anyone trying to fight on it- you'd forget what you were doing.
Certainly it's hard to imagine anybody getting violent on valium, as well
