For me, I think I was really lucky. The first time I ever smoked, I smoked a couple of bowls with a my ex and her friend, and it was amazing. I mean, I coughed like I never had before, but I got high as shit, and felt nothing but good.

It varies pretty greatly person to person. If I were you, I would give it another shot when you're feeling good, and are at home. Try taking it slow next time. Take a couple of hits off a pipe or j, and let it set in. It is really easy to smoke way too much if you do it all at once.
But yeah, man. I know a couple of people that don't smoke weed cause' they get crazy paranoid, or just feel bad. Hell, I know a chick that gets really violent when she smokes.

My point is, don't get set on expectations, take it easy, and have a good time
