Been there, done that! Just don't pull too hard! Make sure your mouth is not going through "cotton mouth". A dry mouth is bad= more bacteria. I had most of my teeth removed several years ago. I toked on the way home, sipping ice water in between hits. As long as your mouth is clean and moist, and you don't pull too hard on the pipe, bong or joint, you should be OK. - Granny:hippy:
