Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens. This new potential health hazard was revealed in a multi-institutional study led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab). "The burning of tobacco releases nicotine in the form of a vapor that adsorbs strongly onto indoor surfaces, such as walls, floors, carpeting, drapes and furniture. Nicotine can persist on those materials for days, weeks and even months. Our study shows that when this residual nicotine reacts with ambient nitrous acid it forms carcinogenic tobacco-specific nitrosamines or TSNAs, " says Hugo Destaillats, a chemist with the Indoor Environment Department of Berkeley Lab's Environmental Energy Technologies Division.
NCKU Team Revealed New Mechanism Of Why Tobaccos Cause Cancer, Published In The Journal Of Clinical Investigation
In the history of humans fighting against cancer, the relationship between tobaccos and cancer has been an important subject for the academic and clinical research. By understanding the mechanism of why cancer is caused by tobaccos, scientists around the world all anticipate to solve the mystery of cancer and find the way of prevention and cure.

The Department of Health unveiled a new Tobacco Control strategy today to halve the number of smokers from 21% to 10% of the population by 2020. Different measures are being considered including the removal of branding from packets and banning cigarette vending machines, as will happen in Scotland in 2011. The new strategy will also ensure that every smoker will be able to get help from the NHS to suit them if they want to give up. Research by the Department of Health shows that seven out of ten smokers want to quit. Last year alone, over 370, 000 people stopped smoking thanks to the free support from the NHS. The key points set out in the strategy are: - Stopping young people being recruited as smokers by cracking down on cheap illicit cigarettes.

A parent's existing health habits or behaviors, like cigarette smoking, may influence the likelihood that they will have their daughters vaccinated against HPV. According to survey results on correlates of HPV vaccine use, whether parents would choose to vaccinate their daughters was not associated with one's background or medical history, but was more closely associated with certain behavioral factors of the parents. Results of this survey are published in the February issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. "Whether or not respondents indicated that they would vaccinate their daughters against this cancer-causing virus was associated with physical activity, non-use of complementary or alternative therapies and, more surprisingly, cigarette smoking, " said lead researcher Carolyn Y.
Senator Frank R. Lautenberg (D-NJ), a longtime Senate leader in the fight against the tobacco industry, applauded the Food and Drug Administration's decision to continue their efforts to regulate electronic cigarettes. At Lautenberg's urging, the FDA is appealing a federal judge's ruling in the Smoking Everywhere case that the agency lacks the authority to regulate e-cigarettes as drug-device combinations. "There have been no clinical studies to verify the safety of these products or the long-term health effects. To the contrary, FDA's own laboratory analyses of electronic cigarette samples found them to contain carcinogens and toxins such as antifreeze components, " Lautenberg wrote in a letter to FDA Commissioner Margaret Hamburg.
Four scientists at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have been awarded more than $2.2 million from the National Institutes of Health (NIH) to research the effects of nicotine and develop new tobacco-related drug therapies. The grants will fund three separate research projects at the Phoenix-based institute in the next several years. Ronald J. Lukas, PhD and Vice President of Research at Barrow, is one of the world's leading experts on nicotine and has spent much of his research career studying its impact. Lukas' research lab, shared by Paul Whiteaker, PhD, is the main recipient of the funding. The Barrow laboratories of Jie Wu, MD, PhD, and Yongchang Chang, MD, PhD, also will receive funding from the grants.

The Royal College of Nursing (RCN) welcomed the new Department of Health strategy to halve the number of smokers by 2020. Dr Peter Carter, Chief Executive & General Secretary of the Royal College of Nursing (RCN) said: "The serious health consequences of tobacco are undisputed, and nurses will welcome moves to reduce the number of people who continue to smoke. The plans include robust ideas to stop young people smoking in the first place, such as clamping down on the sale and marketing of tobacco.

Parents are often motivated to quit smoking when they welcome a new baby into their family. Catching them while they're still in the hospital may be ideal, according to the study, "Using the Postpartum Hospital Stay to Address Mothers' and Fathers' Smoking: The NEWS Study, " published in the March issue of Pediatrics (appearing online Feb. 1). This pilot trial, known as Newborns Excel Without Secondhand Smoke (NEWS), assessed the smoking status of all new parents giving birth at a hospital child birth center during a 14-month period. Researchers enrolled 101 new parents who were smokers or who had recently quit smoking. About half received an in-person counseling session and an invitation to enroll in a telephone quit line.
