Abstract
An improved smoke control device for smoking articles which contains a valve operative to close off the flow of smoke drawn through the smoking article depending upon the pressure drop or draw rate of each individual puff. Preferably, the valve comprises a resilient flap member responsive to the puff pressure drop for restricting or closing off smoke drawn through the smoking article and which will reopen after the pressure is relieved, thereby limiting each puff to a predetermined yield consistent with that obtainable in a normal puff.
