Because smoking cannabis is a sharing experience, we pass joints, pipes, and bongs that have touched the lips of countless friends and strangers. That's why Moose Labs came up with the MouthPeace, a filter and personal mouthpiece for pipes and bongs. You even stick a blunt in if it's fat enough. The Moose MouthPeace bong filter has a carbon filter disc on the inside that is replaceable. It reduces harshness and filters out a bunch of those gross combustibles that taste so bad and you don't want going into your lungs. Besides filtering, the MouthPeace covers the top of a pipe so you can use it instead of the germ covered surface that your friend just put their lips on.
