Abstract
UNBURNED American cigarette tobacco is an excellent source of tumour-promoting agents1. The aqueous extract from as little as one-half cigarette per day is sufficient to produce skin tumours in mice painted previously with 125 µg of 7,12-dimethylbenz[α]anthracene (DMBA). The work recorded here gives further information about the properties of the active substance.
