New models Offer Cigarettes not lower cancer risks

New Cigarettes Designs Don't Offer Lower Cancer RisksTobacco company's description of his new cigarette brand seems to promise a lot.

"Can mean less risk of cancer associated with smoking," the firm on its site, makes it a natural choice "for smokers who have decided not to, but who are interested in a cigarette that answers questions about some smoking-related diseases, including cancer."Other tobacco companies, in a print advertisement for the brand, have crowed "all in taste; Less of toxins".

But a study by Dr. James f. Pankow of Oregon Health & Science University, snuff out allegations of tobacco companies to smoke these newly marketed "potentially reduced-exposure products" (PREP) cigarettes are safer.The study, displayed on March 16 in the journal Cancer Epidemiology Biomarkers & prevention, found that the predicted risk of lung cancer from PREP cigarettes are not meaningful lower than for conventional cigarettes that most smokers puff on a daily basis.

The report shows that science does not adequately understand the sources of cancer, the effects of smoke from conventional cigarettes; as a result, even if some of the known toxins, such as formaldehyde, arsenic and cadmium-removed from cigarette smoke through the new designs as PREP, tobacco companies are not the risks of cancer had been reduced to any meaningful extent. Paper indicated that this makes the promise of reduced damage based on such removal "speculative and unverified".

"Despite all the years of research, we can only represent a small proportion of the carcinogenicity of smoking conventional cigarettes," said Pankow, Ph. d., Professor of environment and biomolecular systems at OHSU's OGI School of Science & Engineering, and a member of the OHSU Cancer Institute.

"People have known for a long time that it is carcinogenic substances in tobacco smoke, but if you look at the levels of conventional cigarettes and expected strength of these known carcinogens, and you aggregated all predicted carcinogenic activity, you don't come close to what is observed for the number of smoking-related lung cancer in the population," he says.

Grover Bagby, M.D., Professor of Medicine (Hematology and medical oncology) and Director of the Institute of cancer OHSU said "the tobacco industry, we believe that the risks to public health by tobacco consumption can be reduced by using the new tobacco products.Dr. Pankow and colleagues have questioned the idea of a strong epidemiological. Cancer Institute actively support the translational research project of Dr. Pankow designed biologically confirm his epidemiological studies ".

Pamela Clark, Ph. d., senior research scientist at Battelle Center for public health research and evaluation in Baltimore, said Pankows study "has profound effects on tobacco product regulation."Clark is studying the effects of the comprehensive tobacco use prevention and control of applications, as well as advertising and promotion of tobacco products in stores.

"Dr. Pankow survey shows that only the few known harmful compounds from tobacco smoke should not significantly reduce the risks of smoking," said she.

Pankows Group reviewed carcinogenic deliveries from 26 trademarks of conventional "regular", "light" and "ultra light" cigarettes; With the help of the US Environmental Protection Agency data for the strength of carcinogens, Pankow's team showed that these deliveries only able to account for about 2 percent of lung cancer risk to smoke cigarettes.

Pankow said: "because we cannot recognise the risks from smoking conventional cigarettes, it doesn't do much to simply remove some of the known toxins, an analogy might be someone who abuse alcohol drink 10 beer a day, but says it will cut down to 9".

Such findings could lead to tougher restrictions on how tobacco companies promote their products, legislation is deemed necessary now on whether and how the u.s. Food and Drug Administration should be allowed to regulate cigarettes in Congress.

-The marketing claims need to be regulated closely. tobacco companies should not be allowed to do, expressed or implied promises cannot be supported completely, "said Pankow.
