titleOfInvention Smoking apparatus having convoluted filtering/heat-reduction passageway
abstract A filtering/heat-reduction smoking apparatus for various tobacco products. A convoluted passageway in the apparatus removes tar and other harmful chemicals and reduces the heat of the smoke thereby increasing the user's pleasure. Air intake holes also aid in reducing heat. The design requires the smoke to travel through a convoluted passageway many times greater than the length of the apparatus. The apparatus disassembles quickly and easily for cleaning.
