Tobacco and Carcinogens
19() Smoking, Associated Diseases and
Causality -- Dr. S.J. Green.
"Thus the argument that since there are heavy smokers who do not
have lung cancer (and, of course, the majority do not) and because there
are some rare cases of non-smokers who do have lung cancer then smoking
does not cause lung cancer, is totally fallacious.... ....Thus for
male smokers in the U.S., the U.S.A. and several other countries from
the epidemiological evidence alone it can be concluded that smoking
cigarettes causes lung cancer and some other respiratory diseases."

benzo(a)pyrene as the result of the addition of potassium carbonate does
not reduce tumorigenicity in mouse skin painting tests.

1967. "(1)...the carcinogenic effect of smoke is not simple.
It may well be a combination of initiators and promoters, a hypothesis
that is well founded on other experimental evidence.
(2) The carcinogenic effect of smoke condensate on mouse skin cannot be
accounted for by the presence of benzpyrene known to be there."

1971 "Cigarette smoke condensate does not produce instant tumours. The
earliest tumours produced at Battelle have occurred about the 20th week
of an experiment, and usually the time is about 28 to 32 weeks.
...only 15% of the animals escaped becoming tumour-bearing during the
remainder of the experiment.

Increasing the Delivery of Nicotine in Cigarettes.
1965. "Their (new smoke research facilities) approach seems to be
to find ways of obtaining maximum nicotine for minimum tar. Approaches
being used include:
(a) P.E.I. treatment of filters.
(b) Nicotine fortification of cigarette paper
(c) Addition of nicotine containing powers to tobacco
(d) Alteration of blends"
