Water pipes, also referred to as bongs, use water filtration to deliver smooth, cooled hits while retaining lots of great flavor. This is the most popular method of smoking for many reasons. The filtered smoke delivered from bongs is a lot easier on the lungs than when using a dry pipe. The smoke passes through the water, it breaks up into smaller bubbles as it percolates. It cools the smoke to a temperature more comfortable to inhale. The result… an incredibly smooth hit!
