Dr. Boris Dzilkovski at Cornell University in Ithaca, N.Y., said from a healthcare perspective, the best cigarette is no cigarette, but a less toxic cigarette may be helpful for the millions of people a year who try to quit smoking.
"The implications of this technique can help reduce the hazardous effects of tobacco smoke because free radicals are a major group of carcinogens," said Dzilkovski, a co-author of the study.
Using the natural antioxidant extracts -- lycopene, the bright red pigment and phytochemical found in tomatoes and other red fruits and vegetable and grape seed extract -- in cigarette filters, drastically reduced the amount of cancer-causing free radicals passing through the filter, the researchers said.
The findings were published in the Journal of Visualized Experiments, a video journal. It is at:
