Smoking and Tobacco Control Monograph No. 7 
every combustion. Hydrogen cyanide comes from every combustion of a 
protein-containing component. Phenol comes from any combustion. The 
tobacco-specific nicotine-derived nitrosamines, which are strong carcinogens, 
come only from tobacco. I think the consumer should know that. 
DR. GUERIN: To my knowledge that is the one class of chemicals that might 
be considered in addition, although it would be very difficult to do, relative 
to tar and nicotine and CO measurements. 
DR. HOFFMANN: I personally do not think we confuse the smoker. 1 think 
we can let them know on the package that cigarette smoke contains toxic 
agents: hydrogen cyanide and known carcinogens, chloraminobiphenyls, 
benzo(fl)pyrene, and the nicotine-derived nitrosamines. We should say that, 
though not quantitatively. Giving numbers is only confusing here. 
DR. FREEMAN: Before we entertain other questions, I would like to have the 
committee's sense of whether you support what Dr. Hoffmann has just said, 
which seems to be a good summary of what we have said so far? Is there any 
disagreement with what Dr. Hoffmann has just said? 
[NO RESPONSE] 
Then we will take that as a consensus, and we will go on to consider it 
further in the latter part of the day. 
You had another comment. Dr. Petitti? 
DR. PETITTI: Just to emphasize that this information should not be 
quantitatively presented to the consumer because of the potential for 
misinformation. 
DR. FREEMAN: My understanding relative to Question 2 is that there are 
certain elements that are proven to be harmful to human beings that are 
within tobacco that should be listed, though this panel is not recommending 
which specific compounds; that they should not be listed according to 
quantity; and that they should not undergo the same testing that we are 
recommending for tar, nicotine, and CO. I will take that as a consensus at 
this point. 
If that is sufficient for that question, I would like to go on now to the 
third question that we have been asked to consider. 
Question 3. Docs the FTC protocol provide information useful to consumers 
in making decisions about their health? 
Yes, Dr. Petitti? 
DR. Idn rrri: I think that in the context of the purpose of the FTC protocol, 
which is to provide information that allows consumers to choose cigarettes 
that reduce their risk of disease, the current M C protocol is misleading in at 
least two important ways. I’irst, it presents the consumer with a single 
number, thus implying that the consumer will receive exactly that exposure. 
.Second, I think that the numbers when [)resented as numbers implicitly
