The condensates collected after pipe smoking of a natural tobacco and a cavendish type tobacco, either unwrapped or wrapped in a paper "saver" bag, were tested for mutagenicity in the Salmonella/mammalian microsome assay with strains TA100 and TA98. The number of revertants induced with cavendish type tobacco in the presence of metabolic activation (mouse-liver S9) was higher in both strains compared to the natural tobacco. Further increase in the number of revertants (approx. 3 times) was consistently seen when the tobacco was smoked after paper wrapping "savers".
