Cornell University researchers using natural antioxidants in cigarette filters may have found a cost-effective method to reduce inhalation of carcinogens by smokers, Science Daily reported.

Lycopene, an antioxidant pigment found in tomatoes, and grape-seed extract inserted in filters demonstrably lowered the amount of cancer-causing free radicals passing through the filter. The technique is cheaper than using haemoglobin and activated carbon, according to the Science Daily website.
Dr Boris Dzilkovski, a co-author of the study done at the university in Ithaca, New York, was cited saying the technique can help lower hazardous effects of tobacco smoke. The research will be made public by the Journal of Visualized Experiments, according to Science Daily. (pi)
