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 [...]
