I've seen other people throw up from smoking but I never have from just smoking. Now being drunk already and then smoking.....usually no good. One of my buddies hit a double perculator bong once that was about 3 1/2 ft long and took 2 HUGE rips to clear if it was full and coughed for about 3 minutes straight. He coughed so much his nose started bleeding. He just looked at us and was like "well you know it's good shit if it makes your nose bleed"
