I puked twice, both after a pretty hefty session with a few joints and blunts (around here, there's almost never a bong or something like that), a tulip and I guess some other kind of joint also. Actually, I puked twice seperately but ah well under the same conditions. I don't really remember the second time though I'm sure I puked, and the first time was so damned funny I'll always remember. I was just cycling with a friend to a skatepark to buy some more drugs and halfway I was imitating Jafar from Aladin, with this rteally raw voice. It kinda hurts my throat to do and ofcourse my mouth was dry already, so I got into a coughing fit because I wanted to finish a good Jafar. From that coughing fit, I had to puke really fast, but I was still cycling, so in the middle of cross road (yes, there were cars), I stopped for a split second, leaned to the right and puked just a tiny bit and then I cycled on. I felt pretty good after that.

But I've never felt sick from cannabis tho.
