Snuff and chewing tobacco linked to increased risk of fatal MI or stroke

Source: WebMD Author: Marlene Busko Lyon, France - Smokeless tobacco—such as snuff and chewing tobacco—is not harmless when it comes to heart health, according to a new meta-analysis [1]. A review of 11 studies from Sweden and the US, almost entirely in men, showed that smokeless-tobacco users had an increased risk of death from MI or stroke. The study, by researchers at the International Agency for Research on Cancer(IARC), is published online August 18, 2009 in BMJ. Contrary to common belief that smokeless tobacco has very little effect on health, these products have been shown to increase cancer risk, coauthor and IARC researcher Dr Kurt Straif (Lyon, France) told heartwire. "There is sufficient evidence for a causal association between smokeless tobacco and oral and pancreatic cancer [2] and probably also esophageal cancer [3]," he said. "Now, this study adds evidence that smokeless tobacco causes death from cardiovascular diseases," Straif summarized. Widespread, growing use of snus Types of smokeless tobacco used in North America and Europe include dry snuff that is inhaled, as well as moist snuff (called snus in Sweden) and chewing tobacco (or spit tobacco), which are sucked inside the cheek. These products have been around for centuries, and after a decline in consumption for most of the 20th century, use has rebounded in the past few decades, the authors write. In 2000, 23.9% of men and 4.1% of women in Sweden reported using snus daily or occasionally. In the same year, in the US, 4.4% of men and 0.3% of women were [...]

Oral use of Swedish moist snuff (snus) and risk for cancer of the mouth, lung, and pancreas in male construction workers: a retrospective cohort study

Source: www.thelancet.com Author: Juhua Luo, MSc et al. Background: Although classified as carcinogenic, snuff is used increasingly in several populations. Scandinavian moist snuff (snus) has been proposed as a less harmful alternative to smoking, but precise data on the independent associations of snus use with site-specific cancers are sparse. We aimed to assess the risks for cancer of the oral cavity, lung, and pancreas. Methods: Detailed information about tobacco smoking and snus use was obtained from 279 897 male Swedish construction workers in 1978—92. Complete follow-up until end of 2004 was accomplished through links with population and health registers. To distinguish possible effects of snus from those of smoking, we focused on 125 576 workers who were reported to be never-smokers at entry. Adjusted relative risks were derived from Cox proportional hazards regression models. Findings: 60 cases of oral, 154 of lung, and 83 of pancreatic cancer were recorded in never-smokers. Snus use was independently associated with increased risk of pancreatic cancer (relative risk for ever-users of snus 2·0; 95% CI 1·2—3·3, compared with never-users of any tobacco), but was unrelated to incidence of oral (0·8, 95% CI 0·4—1·7) and lung cancer (0·8, 0·5—1·3). Interpretation: Use of Swedish snus should be added to the list of tentative risk factors for pancreatic cancer. We were unable to confirm any excess of oral or lung cancer in snus users.

Philip Morris expects FDA regulation will be a perk

Source: Richmond Times Author: David Ress Jun 23, 2009 (Richmond Times-Dispatch - McClatchy-Tribune Information Services via COMTEX) --  One of the real tests of how federal regulation will affect tobacco use could be something you'll spot at a convenience store counter. A new law signed by President Barack Obama yesterday will, among many changes, move all tobacco products -- snuff and cigars as well as cigarettes -- behind the counter. How they share space back there could clear the way for more competition in a market now dominated by Henrico County-based Altria Group Inc. It's competition that Chesterfield County-based Swedish Match North America is hoping for, and a rule it believes could lead to something it's long wanted: more space on retailer's shelves for its snuff and chewing tobacco. "It's back to old fashioned blocking and tackling, how to be more competitive -- including against cigarettes," said Gerry Roerty, Swedish Match's president and general counsel. Both Richmond-area tobacco companies broke with most of the rest of the tobacco industry in supporting the regulation of tobacco by the U.S. Food and Drug Administration. "We have consistently advocated for federal regulation that recognizes the serious harm caused by tobacco products," said Michael E. Szymanczyk, chairman and chief executive of Altria, parent of Philip Morris USA, the largest cigarette-maker. But critics say Altria's nearly decade-old support of regulation is a way to lock in its dominant share of the U.S. market -- both for cigarettes and now oral tobacco, after buying the nation's No.1 smokeless tobacco-maker this [...]

Chewing tobacco use surges among boys

Source: Msnbc.msn.com Author: Staff WASHINGTON - Use of snuff and chewing tobacco by U.S. adolescent boys, particularly in rural areas, has surged this decade, a federal agency said in a report on Thursday that raised concern among tobacco control advocates. The use of such smokeless tobacco products increases the risk of oral cancer as well as heart disease and stroke. It leads to nicotine addiction just like cigarette smoking. The report by the U.S. Substance Abuse and Mental Health Services Administration showed a 30 percent increase in the rate of smokeless tobacco use among boys aged 12 to 17 from 2002 to 2007. Use by adults remained stable. In 2007, the report estimated that 566,000 boys in that age group had used chewing tobacco or snuff. "This trend toward more smokeless tobacco use by kids is of great concern," Danny McGoldrick, vice president for research at the Campaign for Tobacco-Free Kids advocacy group, said in a telephone interview. "This is an industry that has a history of targeting kids because they know that's when everybody starts," he added. Among adolescent boys, the rate of use of smokeless tobacco rose from 3.4 percent in 2002 to 4.4 percent in 2007, according to the report. McGoldrick said the increase occurred as smokeless tobacco companies greatly increased their spending on marketing and introduced a new range of products. The findings reiterated the need for the U.S. Food and Drug Administration to have the power to regulate tobacco products, as legislation being considered by [...]

Smoke signals

Source: waldo.villagesoup.com Author: Dr. Jonathan M. Goss, DDS Dr. Jonathan M. Goss and the Staff of Camden Hills Dental Care would like to provide you with the following information from the Academy of General Dentistry for the education and care of your oral health. Smoke Signals Using tobacco can harm your mouth, including your teeth and gums, in a number of ways. There is no safe form of tobacco—using it produces many problems and risk factors, from tooth discoloration and gum disease to throat, lung, and oral cancer, and ultimately, even death. It is important to understand what happens to your mouth when you use any form of tobacco, and to discuss those effects—and how to quit—with your dentist and physician. What happens to my mouth when I smoke? Smoking reduces blood flow and the supply of vital nutrients to your gums, including vitamin C. Without the proper nutrients, you can develop gum disease, bone loss, and even tooth loss. This is because smoking triggers the accumulation of bacteria in plaque. Smoking also reduces the amount of saliva that flows through your mouth. Saliva is important for cleaning your mouth and preventing tooth decay. In addition, when you smoke, the temperature in your mouth increases and the heat kills important cells in your mouth. You also can see the effects of tobacco use. Nicotine and tar, the major ingredients of cigarettes, discolor your teeth—yellow and brown stains will appear and the sticky tar deposits will adhere to crevices. The roof [...]

Smokeless tobacco ups oral cancer risk 80 pct – WHO

Source: in.reuters.com Author: staff Chewing tobacco and snuff are less dangerous than cigarettes but the smokeless products still raise the risk of oral cancer by 80 percent, the World Health Organisation's cancer agency said on Tuesday. The review of 11 studies worldwide showed people who chewed tobacco and used snuff also had a 60 percent higher risk of oesophagus and pancreatic cancer. The researchers sought to quantify the risk of smokeless tobacco after a number of studies differed on just how dangerous the products were, said Paolo Boffetta, an epidemiologist at the WHO's International Agency for Research on Cancer. "What we did was try to quantify the burden of smokeless cancer," he said in a telephone interview. "This has never been attempted in such a systematic way before." The researchers, who published their findings in Lancet Oncology, did this by looking at population-wide studies and trials of both humans and animals. They found frequency of use varies greatly both across and within countries, depending on sex, age, ethnic origin and economic background, and were highest in the United States, Sweden and India. They also found that while snuff and chew were less dangerous than smoking because they were not linked to lung cancer, getting cigarette users to switch was not good public policy. "If all smokers did this there would be a net benefit," Boffetta said. "The point is we don't know whether this would happen and there is no data to suggest these smokers would stop or switch."

Short-term effects of spit tobacco suggest long-term health risks

Source: www.mayoclinic.org Authors: Robert Wolk et al. Use of smokeless tobacco raises short-term adrenaline levels in the bloodstream by more than 50 percent and also causes the heart rate and blood pressure to surge, according to findings of a Mayo Clinic study published this week in Journal of the American College of Cardiology. The results suggest that snuff tobacco has a powerful stimulant effect but that it also dampens the body's normal protective responses to blood pressure elevation. The study of 16 young men who were habitual spit tobacco users measured their responses 30 minutes after dipping snuff. These readings were compared with measurements from another session involving the same participants after they had used a placebo product that was similar in taste, color and texture but did not contain tobacco or nicotine. The study was randomized and double-blinded; neither the researchers nor the subjects were told when they were taking the placebo and when they were using the tobacco product. After snuff use, heart rate increased by about 15 beats per minute (25 percent), systolic blood pressure went up by 12 mmHg (10 percent), and measurements of adrenalin in the bloodstream increased by more than 50 percent. "These results suggest a very significant excitatory effect of substances contained in spit tobacco on the part of the nervous system regulating the heart and blood vessels," says Virend Somers, M.D., Ph.D., the Mayo Clinic cardiologist who led the study. "Although we did anticipate some increase in blood pressure, we were surprised [...]

Free nicotine content and strategic marketing of moist snuff tobacco products in the United States: 2000–2006

Source: Harvard School of Public Health, Boston, Massachusetts, USA Authors: H R Alpert, H Koh, G N Connolly Background: From 2000 to 2006, moist snuff sales have increased and now account for 71% of the smokeless tobacco market. Previous research has shown that major manufacturers of smokeless tobacco products manipulated free nicotine, the form most readily absorbed, to promote tolerance and addiction. Aim: This study examines the possibility that company-specific and brand-specific strategies of the major moist snuff manufacturers involve controlling free nicotine content and ease of dosing with products that are designed and targeted to specific groups. This study looks at the current total US moist snuff market with product design data from the Massachusetts Department of Public Health; moist snuff use from the National Survey on Drug Use and Health; market data from ACNielsen; and magazine advertising expenditures from TNS Media Intelligence. Results: (1) The levels of free nicotine of moist snuff products have increased over time for several major manufacturers; (2) the number and variety of sub-brands have increased over time; (3) changes in design, as reflected by variation in free nicotine associated with pH or tobacco leaf, or both, have enhanced the ease and uniformity of dosing; (4) marketing through price and advertising has increased; and (5) youth use has increased. Conclusion: A combination of factors including brand proliferation, control of free nicotine and product design has most likely resulted in the expanded consumption of moist snuff, particularly among young people.
