I've only had that feeling when I hit the pipe, blunt, bong hard as fuck. Probably 3x in my life but never puked, wanted to but didn't want to kill any of my boys buzz.

The first time was off a gravity bong ... I had virgin lungs and they filled the entire jug of chronic smoke. I coughed for a straight minute while my friends were just laughing their asses off. The high I had that night was incredible.

The last time was with two buddies in a car and a pipe. I just took two deep puffs and this shit was buRRRRRRRNINGGGGGGGGG while it was going down. I could only hold it in for like 5 seconds and started coughing it all out. It was pretty funny.
