Section II 
ciliatoxic agents and hydrogen cyanide, for example. It could be categorized 
as carcinogens and then certain carcinogens. I think, given all the 
discussion that we have had both yesterday and today about the potential 
misinterpretation of numbers, it would seem to me that to add to that 
confusion by a whole new set of numbers would not be serving the interests 
of the consumer. 
DR. FREEMAN: Thank you. Dr. Rickert. Dr. Stitzer? 
DR. STITZER: I am totally in favor of more information being given to the 
consumer, but I want to bring up priorities and to point out that cigarette 
packs are not very big, and personally I think it is more important to convey 
the information about the variability of yield in some prominent way on a 
cigarette package rather than using that space to list hundreds of chemicals. 
Now, what I would be interested in seeing is a kind of package insert 
disclosure information that would be put in cigarette cartons. That might 
be a better format for delivering the information. 
DR. FREEMAN: Dr. Petitti? 
DR. PETITTI: I would like to provide support for both of the prior 
statements, particularly that perhaps cigarettes need to have prominently 
displayed the fact that they contain some list of selected carcinogens but 
not to portray that information in a quantitative fashion. I do not think we 
have the ability to decide which of the numerous carcinogens in cigarette 
smoke is the one or the ones that quantitatively are related to the various 
forms of cancer caused by cigarettes and that we would be further misleading 
the consumer by making them believe that, for example, a cigarette with low 
levels of chemical X is better for them than a cigarette with a higher level of 
chemical X. I do not think we will ever have the epidemiological database 
that will allow us to link these various carcinogens quantitatively with risk 
of any of the human cancers. 
DR. FREEMAN: Yes, Dr. Guerin? 
DR. GUERIN: If we had a list of common cigarette smoke toxins on 
packages, would that not discourage the industry from producing products 
that have undetectable quantities? Wouldn't we need some kind of a level 
of detection to determine when we are at basically nothing because there 
are advanced products that are being marketed or may be being marketed? 
DR. FREEMAN: Let us go to Dr. Hughes first. 
DR. HUGHES: People are interested in function. They do not care about the 
names. They care about what these things do. So, my proposal would be to 
get the word "cancer-forming" agents on there. That is the important thing, 
not whether it is this long name or that long name or whatever because that 
is the important thing that consumers need to know. 
DR. FREEMAN: Yes, Dr. Townsend?
