What's the benefits of using a bong?

The main benefit of using a bong is that it uses water filtration! The smoke is pulled through the water before it hits your lungs. As it travels through the water the smoke is forced into small bubbles and this causes it to lose a lot of it's heat. This is a great benefit on it's own, but the water also filters out a lot of the larger particles in the smoke that can be damaging to your lungs. Things like ash, tar, and even butane from your lighter.

This results in a cleaner and smoother toke!
