Is snus a safe alternative to cigarettes? Snus is being touted as a safe alternative to cigarettes. Studies cite low if non-existent rates of associated lung cancer, with a very mild uptick in pancreatic cancer - the studies were carried out in sweden, a

Snus: Snus is also known as swedish snuff and is a moist powder tobacco product originated from a variant of dry snuff in the early 19th century in sweden, consumed by placing it under the lip for extended periods of time. While it has been touted as an alternative to smoking and traditional "chewing" tobacco, there are concerns regarding health risks associated with its use. Although some say smokeless tobacco poses fewer health risks than cigarettes, they note that it has been linked to various types of cancer and warn against using any tobacco product.

There are contradictory studies on the risk for cancer and other health problems. In a study from the karolinska institute in stockholm, sweden, published in the international journal of cancer in 2008 found a statistically significant increase in the incidence of the combined category of oral and pharyngeal cancer among daily users of snus (incidence rate ratio 3.1, 95% confidence interval 1.5-6.6) was found. Overall mortality was also slightly increased (hazard ratio 1.10, 95% confidence interval 1.01-1.21). In an earlier study published in lancet in 2007, 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). These differences may also lie in the variations of smokeless tobacco in the marketplace. In a study from 2008, researchers found a large variation in the levels of some toxic compounds and carcinogens analyzed in american and swedish smokeless tobaccos.

Based on this and other studies, while smokeless tobaccos provide some protection against lung cancer, the overall health risks or benefits have not been clearly determined and the best advice is to avoid using any tobacco at all. ...Read more
