smoke producing agent, a smoke nucleation agent, a 

 flavouring agent and a physiologically active agent. 



2. A method according to claim 1, wherein the additive 

 comprises a stable nicotine salt.

Adding nicotine to filters 



* Philip Morris Incorporated. Pat. 3,584,630, 1971. 



The patent describes the addition of a "nicotine releasing 

 agent" to a filter. The "nicotine releasing agent" is 

 nicotine adsorbed onto carbon black. The idea is to add 

 nicotine to the mainstream smoke without adding to the "tar" 

 fraction. The patent reads in part: 



Maintaining the nicotine content at a sufficiently high 

 level to provide the desired physiological activity, 

 taste, and odor which this material imparts to the 

 smoke, without raising the nicotine content to an 

 undesirably high level, can thus be seen to be a 

 significant problem in the tobacco art. The addition 

 of nicotine to tobacco in such a way that it remains 

 inert and stable in the product and yet is released in 

 a controlled amount into the smoke aerosol when the 

 tobacco is pyrolyzed, is a result which is greatly 

 desirable. 



The present invention provides a solution to this 

 longstanding problem and results in accurate control of 

 the nicotine which is released in tobacco smoke. By 

 employing the nicotine-releasing agents and methods of 

 the present invention, it is possible to incorporate 

 exact amounts of nicotine in a tobacco composition, 

 which will remain constant over extended periods of 

 time and which will ultimately yield a smoke containing 

 a controlled amount of nicotine. 



The. present invention may also be used to incorporate 

 flavorants into tobacco smoke. 



Nicotine is treated as something quite separate and apart 

 from flavorants, and the patent states that nicotine is 

 needed "to provide the desired physiological activity, 

 taste, and odor." Philip Morris does not presently sell 

 cigarettes with charcoal filters in the U. S., but in Japan, 

 its Lark brand features a charcoal filter.
