Act III, Scene 4: Hazardous When Burned
"COUMARIN - (codes: KESCON, ROMINK, SYNLOR, SYNTHOS) Tobacco and food
additive used in synthetic vanilla, chocolate and other confections for
nearly 75 years - is found in tonka beans and was banned in 1954 because
it could disguise unpleasant odors and cause liver damage in rats and dogs."
"Pesticides and Potentially
Hazardous Additives," 1327.01, p. 7
Among the many lists that B&W wrote up during the eighties were several
dealing with the additives in cigarettes, which had never been publicly
disclosed, and which some B&W scientists worried could cause cancer
when burned.
The lists contain everything from cocoa (code named BINNET) to chemical
additives like propylene glycol (code name GRELANTER). Also listed is coumarin, blamed as a possible carcinogen in animal studies, that the company admits was used until recently
in B&W's pipe tobacco.
