Acceptable ' cigarene in light ot the present health anitude. The aims 

 of the smoke chemistrv group should be more specific than in the past. 

 We must not forget the major goals of the Division and become bogged 

 down m procedures on anaJyticaJ methodologies. For example, one of 

 our major purposes is to remove polynucleax hydrocarbons from 

 cigarette smoke, not just to develop a method of detecting 

 ben20(a)pyrene in smoke. 



Dr. Bavley then stated that we should approach the problem with 

 definite "bench marks " in mind. 



What are the "bench marks"' in the Smoke Chemistry Problem? 



1 . Nicotine removal . Accomplished - using low nicotine tobacco and/or 

 extracted tobacco to remove nicotine selectivity from tobacco. 



2. Removal of phenol . Accomplished by means of the cellulose acetate 

 filter with plasticizers. 



3. Polvnuclear hydrocarbons removal . We should have this completed 

 during 1964 - major effort. 



4. Vitr^y iiT^l oes removal . We should also have this completed dunng 

 1964. 



Status of Polynuclear Hydrocarbon Removal fr om Smoke. 



An improved analytical method for the determination of benzo(a)pyrene 

 and several other polynuclear hydrocarbons should be completely worked 

 out by January 31, 1964. This will enable screening of various chemical 

 additives and/or treatments of cigaienes for polynuclear hydrocarbons 

 delivery. 



A 1968 Liggett and Myers internal memorandum summarized the results of an 



important meeting of the scientific directors of all of the major tobacco 



companies, held in Hilton Head, South Carolina, Febiuary 14-16. Attending the 



meeting were: E. Harlow, American Tobacco Co.; R.E. Griffith, Brown and 



Williamson; M. Senkus, R.J. Reynolds; H. Wakchat. Philip Morris; A. Spears. P. 



Lorillard; and W. Bates, Liggett and Myers. The memorandum from WW. Bates 



to ME. Harrington contained the following statements: 



Our primary purpose was to discuss the scientific aspects of the 

 problems facing the tobacco Industry with specific emphasis on tobacco 

 and health. If a consensus could be reached on this point, we were to 

 discuss and attempt to reach a consensus as to an acceptable way to 

 attempt to solve these problems. 



Shortly after lunch on the second day of our conference I insisted upon 

 discussing what I considered to be the major scientific problems tacmg
