Smoking via a water pipe or bong can offer some advantages over more traditional methods of smoking dry herbs. The water serves as a filter for the smoke, meaning that the smoke will be less harsh on the throat and lungs, and potentially less damaging to the respiratory system. It also helps to cool the smoke, again making it more comfortable to inhale. Additionally, the water can help to trap some impurities in the smoke, meaning that the smoke is cleaner, and potentially more enjoyable. Finally, smoking via a water pipe or bong can be a more social experience, particularly when enjoyed with friends.
