The Federal Trade Coailsslon and the Department of Health and Human 

 Services have both called for legislation that would make the listing, on 

 cigarette packages and promotional material, of tar, nicotine and carbon 

 monoxide yields mandatory. ("By 1985, cigarette companies were required 

 to list tar and nicotine yields in all advertising but were not required 

 to display either value on cigarette packages. At the same time, 

 cigarette companies were not required to, nor did they voluntarily, 

 display carbot> monoxide yields on either packages or promotional 

 materials.")^" 



National Academy of Sciences ; 



"...the attempt to make cigarettes less hazardous by reducing their 

 tar and nicotine yield Is necessarily a crude approach, 

 corresponding to the uncertainty of knowledge about the differential 

 effects of the thousands of components of cigarette smoke and the 

 difficulties In independently manipulating them." ^" 



"It Is possible for a cigarette to be altered in such a say that its 

 'tar' and nicotine content is reduced but certain other harmful 

 effects, for example, the effect of the gaseous phase may be 

 Increased '** 



"... Investigators have reported that carbon monoxide levels are no 

 different in snokers of low-yield cigarettes and smokers of higher- 

 yield cigarettes." 125 



Hew York State Journal of Medicine: 



"When Inhaled, the carbon monoxide (CO) In tobacco smoke results in 

 the formation of carboxyhemoglobln (COHb), so- that approximately 80 

 percent of persons still sinking have COHb levels of from 2 percent 

 to 8 percent. COHb levels are better correlated than smoking 

 history with the developnent of angina pectoris, myocardial 

 Infarction and Intemlttent claudication; the relative risk of 

 developing coronary heart disease is about 20 times greater In 

 individuals with COHb levels or 5 percent or greater than in those 

 with levels below 3 percent. "'2*
