In the study, researchers found that cigarettes made without tobacco or nicotine may be more carcinogenic because they actually induce more extensive DNA damage than tobacco products.

The research team was led by Zbigniew Darzynkiewicz, M.D., Ph.D., professor of pathology. Their study, "DNA damage response induced by exposure of human lung adenocarcinoma cells to smoke from tobacco- and nicotine-free cigarettes," will appear in the June 1 issue of Cell Cycle.sing laser scanning cytometry (LSC) technology to measure DNA damage response to the smoke from commercially available tobacco- and nicotine-free cigarettes, the research team expected to find the alternative products were less hazardous than regular tobacco cigarettes.

However, their data suggest that exposure of cells to smoke from tobacco- and nicotine-free cigarettes leads to formation of double-strand DNA breaks (DSBs). Since DSBs are potentially carcinogenic, the data indicate that smoking tobacco- and nicotine-free cigarettes is at least as hazardous as those containing tobacco and nicotine.

The authors conclude that their methodology to assess the potential carcinogenic properties of tobacco smoke, based on measurement of DNA damage response as assessed by LSC, provides a useful addition to the battery of genotoxic tests for probing cigarette smoke hazards.
