Abstract: This apparatus for the smoking of tobacco and other bulk dried material enables those persons who enjoy smoking to do so in a healthier manner. In the described appliance a water bath cools and filters the smoke before it reaches the mouth and lungs of the smoker. An array of, preferably conical, diffusion screens (210) restricts the size of particulate matter passing through the device from the combustion bowl (180) to the user. By controlling air pressures, valves (240) in series with the diffuser (210) prevent water from flowing into it thereby minimizing the pressure a user must apply to draw smoke through the appliance. This keeps solids from accumulating on or in the diffuser which facilitates cleaning. A static turbine (300) in the throat (110) of the appliance aids additional cooling while reducing the amount of suction that must be applied by a user to clear the main chamber.

Abstract: A zone or plug of porous adsorbent material, primarily activated carbon, is placed in the tobacco rod of a cigarette a short distance from the lighting end thereof. The amount of activated carbon is sufficient for effective removal of volatile smoke constituents while allowing the cigarette to burn continuously. The activated carbon traps volatile smoke constituents in close proximity to the burning coal in the first puffs of the cigarette. As the cigarette continues to burn, the burning coal consumes the activated carbon. The adsorbed smoke constituents are effectively removed without releasing them back into the mainstream smoke. Following the consumption of the activated carbon in the tobacco rod, the cigarette is unchanged from a cigarette of conventional design.

Thereafter additional flavor is released into the mainstream smoke as it passes through the flavor-releasing filter segment. Ventilation is provided to limit the amount of tobacco being combusted during each puff and is arranged at a location spaced downstream from the adsorbent bed to lower mainstream smoke velocity through the adsorbent bed.
