I never said all were druggies.
All I said was that those who went there as druggies usually came back worse.
If I'd not been rejected for military service I'd likely be in the military now, though probably not in a warzone (by now I'd be too senior to be sent into battle, instead being confined to a headquarters' job).
Can't help it that I was born too late for Korea, too early for Afghanistan (we were never in Vietnam).
