A component of many bubblers, bongs, and water pipes that aids in cooling the smoke prior to inhalation, thus making it a smoother hit for your lungs. The diffuser is usually located at the bottom of the downstem, touching the water, and this diffusion allows for air to escape. There are several different types of diffusers, some with more holes than others, but all of them have the same purpose: to provide additional surface area for the formation of bubbles, which helps air flow through the smoking device for a smoother hit.
