Well, I haven't. Partially due to lack of interest, partially due to lack of opportunity - basically, if I was really interested, I could have made it happen. And if it had happened, I wouldn't have objected. But the one time a group of people did say they'd gotten some grass, I felt it was likely that - due to their general competence level - it actually *was* grass. You know, the kind you cut with a lawnmower.
The smell didn't make that seem any less likely. It was pretty funny watching them trying to act stoned though.
I figure if they're that dumb without real pot, they definitely didn't need the real stuff to begin with :P
