By golly, there isn't!
When I was in college, the whole point was to get smoke in the tube :D. Have things really changed that much over the last three decades?
For Christ’s sake we have a president that did hard drugs for years and they swept it under the rug.
I have college sons. They are successful in their own right but I am not naive in thinking they haven’t tried it. I can assure you the fundamentals of bong hits are just like they have always been.
This picture looks phony unless of course he was taking the Clinton approach to smoking marijuana.
It looks the person in the photo is just getting ready to light the bong. Which is probably why there isn’t any smoke in the bong, YET.
