Researchers create a healthier cigarette

From a health care perspective, the best cigarette is no cigarette, but for the millions of people who try to quit smoking every year, researchers from Cornell University may have found a way to make cigarette smoking less toxic.

Using natural antioxidant extracts in cigarette filters, the researchers were able to demonstrate that lycopene and grape seed extract drastically reduced the amount of cancer-causing free radicals passing through the filter. The research will be the 1500th article published in the ground-breaking Journal of Visualized Experiments (JoVE), the only peer-reviewed, PubMed indexed video-journal.

"The implications of this technique can help reduce the hazardous effects of tobacco smoke," said Dr. Boris Dzilkovski, who co-authored the paper, "because free radicals are a major group of carcinogens."

Scientists have tried to make safer cigarettes in the past. Haemoglobin (which transports oxygen in red blood cells) and activated carbon have been shown to reduce free-radicals in cancer smoke by up to 90 percent, but because of the cost, the combination has not been successfully introduced to the market.

JoVE Content Director, Dr. Aaron Kolski-Andreaco, is very excited to be publishing this article as the journal's landmark 1500th article.

"Practically, this research could lead to an alternative type of cigarette filter with a free radical scavenging additive," said Kolski-Andreaco. "It could lead to a less harmful cigarette."

The Journal of Visualized Experiments (JoVE) is the first and only Pubmed and Medline indexed academic journal devoted to publishing research in the biological sciences in video format. Using an international network of videographers, JoVE films and edits videos of researchers performing new experimental techniques at top universities, allowing students and scientists to learn them much more quickly. As of January 2012 JoVE has released 59 monthly issues including over 1500 video-protocols on experimental approaches in developmental biology, neuroscience, microbiology and other fields.
