University of York Research led by the University of York has highlighted the potential cancer risk in non-smokers – particularly young children – of tobacco smoke gases and particles deposited to surfaces and dust in the home. Until now, the risks of this exposure known as 'third hand tobacco smoke' have been highly uncertain and not considered in public policy. However, a new study published in the journal Environment International, has estimated for the first time the...

DNA Danger From Thirdhand Smoke
2013-06-21 04:52:23

Rebekah Eliason for redOrbit.com – Your Universe Online For the first time ever, thirdhand smoke has been found to cause significant amounts of damage to human cells. Thirdhand smoke is the toxic residue that attaches to almost all surfaces leaving a strong odor long after cigarette smoke has dissipated. The researchers from Lawrence Berkeley National Laboratory also discovered in this study that chronic exposure caused more DNA damage than acute exposure. Samples exposed to chronic...

Lee Rannals for redOrbit.com - Your Universe Online Scientists reported in Philadelphia at the 244th National Meeting & Exposition of the American Chemical Society today that they have identified the first oral carcinogen in smokeless tobacco. Researchers said this is the first identification of a strong oral cavity carcinogen found in smokeless tobacco products. "Our results are very important in regard to the growing use of smokeless tobacco in the world, especially among...

The chemical (S)-N'-nitrosonornicotine, or (S)-NNN, which is present in smokeless tobacco products, is a strong oral carcinogen, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4. Although smokeless tobacco products have long been linked with certain cancers, including oral cavity cancers and esophageal cancers, this is the first study to identify a specific chemical present in smokeless tobacco products that induces oral cancer in animals,...

U.S. researchers reported on Tuesday that American cigarettes contain more cancer-causing agents than those in Canada, Britain and Australia. Their study also demonstrated that the amount of these carcinogens in a smoker's cigarette butts directly correlated with tell-tale compounds in the smoker's urine. The study can help researchers try to trace the harmful effects of smoking. "We know that cigarettes from around the world vary in their ingredients and the way they are produced," said...

A team of researchers, led by Yi-Ching Wang, at National Cheng Kung University, Taiwan, Republic of China, has uncovered a potential mechanism by which the tobacco-specific carcinogen NNK promotes lung tumor formation and development. Specifically, they suggest that NNK induces the accumulation of a protein known as DNMT1 in the nucleus and that this protein silences genes that suppress tumor formation. The authors generate several lines of evidence to support their suggested mechanism, one...

A new study on the smokeless tobacco product called moist snuff "” placed between lip and gum "” has led scientists in Minnesota to urge the tobacco industry to change manufacturing practices to reduce snuff's content of carcinogens. Their study is published online in ACS' monthly journal Chemical Research in Toxicology. It reports that this category of tobacco products contains surprisingly high levels of certain toxic and cancer-causing substances. Called polycyclic aromatic...

PETERSBURG, Va., Sept. 22 /PRNewswire-FirstCall/ -- Star Scientific, Inc. (Nasdaq: STSI) makers of low-nitrosamine smokeless tobacco products, announced today that the company will utilize a novel, patented method for cultivation, curing and preparation of tobacco to formulate dissolvable smokeless tobacco products. This new curing process was the subject of a patent application filed in December, 2008. Its use has resulted in tobacco leaf with significantly lower levels of tobacco-specific...

By Megan Rauscher NEW YORK -- Smokeless oral tobacco products such as moist snuff and hard snuff lozenges are not a safe alternative to cigarettes for people trying to kick the habit, as these products contain high levels of cancer-causing compounds. Instead, the best aids appear to be medicinal nicotine replacement products such as the nicotine patch or gum as these products contain only trace amounts of cancer-causing compounds, according to research presented at a cancer prevention...
