As a college student in the 70's many of my peers smoked pot between classes. I had to go to work after classes because I was paying for my own schooling so I had to be ok to go to work. I often tell people I didn't have to buy or smoke it because when they would come back to the group after smoking, they were a show in themselves. If they could have ever seen how out of it, laughing about nothing, not being able to form a simple sentence, I wonder if that would have stopped them. ( WE didn't have cell phones then that we could video them on to show them.lol) I guess I just really am getting old!

It's not worth the trouble it causes. Stand your ground. You sound like you've got a good head on your shoulders. Trust your instincts. They are usually right.
