. y i iTNITED PRESS INTERNATIONAL Maxch 25, 1960 - y ) . - ( Smoking s THE NEW YORK TIfiES New York, New York March 25, 1960 .y , ~ A series of research projects has established, in general ierms„ how much nicotine is absorbed by those who puff cigarettes, ~ those who inhale the smoke and ~ those who chew tobacco or take snuff. . Inhalers, chewers and snuff- takers were all found to absorb about 90 per cent of the nico- tine to which they were exposed. Thi$ was reported yesterday in a Survey of research in this field by Dr. Paul S. Larson of the Medical College of Virginia In Richmond. He spoke at a conference on the effects of' nicotine and smoking on the circulatory sys- tem, sponsored by the New York Academy of Sciences at the Barbizon-Plaza Hotel. A spokesman said the con- ference had been aided by the Tobacco Industry Research Committee, whose grants sup- NICOTINE INTAKE IS GAUGED AT 907o e r t°' Effects on Tobacco Users, Inhalers and Chewers, t!Told by Researchers ported roughly half the pro- jeets reported' on Dr. Larson said that in some cases of chewing tobacco it was possible that 100 per cent of the nicotine would be absorbed, t'1i"subject to such variables as "Iength of retention of the quid, 4 `vigor of 'chewing,' and fre- quency of expectoration." The: research on smokers made use of a nicotine trap be- tween the cigarette and the mouth. Observations were also made of how much wa:: exhaled. Those who merely puff, with- out inhalation, retain onlyabout' 10 per cent, Dr. Larson• said. : Less extensive information on cigar-smoking indicated higher rates, with almost total absorb- tion for those who inhale. -- Dr. J. H. Burn of Oxfcrd Uni- versity in: England reported " that what apparently made the heart' of a smoker beat faster was norepinephrine. This sub- stance is closely related to adrenalin and is found in the adrenal glands as well as in heart' tissue. It is a powerful heart stimulant. Dr. Burn said that in experi- ments with rabbit hearts it was found that injection with reser- pine purged the heart of no- . repinephrine. When the heart had not thus been purged, the administration of nicotine pro- duced a speeding of heartbeats. Warning on Lung Cancer : Speclal to The New York T7mes.
