It comments on the characteristic type of mouth lesion that snus users may get. It found a high incidence of oral, pharyngeal, and overall total smoking-related cancer in the snus users studied.Īn independent report was commissioned by leading Swedish snus producer Swedish Match. This study, reported in 2008, advised that the risk of oral cancer for snus users couldn’t be ruled out. The cancers were in the sites where they had placed snus.Ī similar warning came from a long-term study of 9,976 Swedish snus-using men. These men had used snus prior to cancer diagnosis for a mean of 42.9 years. This 2012 case report of 16 Swedish men with oral squamous cell cancers concluded that Swedish snuff might not be a harmless alternative to smoking. (Note that this is the same study that found an increased risk of pancreatic cancer in the same population.)Īnother Swedish study differed. The study noted that the previous data on smokeless tobacco and oral cancers was sparse.Ī 2007 study of 125,576 Swedish construction workers who used snus but were previously nonsmokers concluded that there was no increased risk of oral cancers in snus users. A 2008 study concluded that the risk of oral cancer for smokeless tobacco users is likely less than that of smokers, but more than that of people who don’t use tobacco.Ī 2013 study, which included snus products from different countries, made a stronger conclusion: that there is a strong link between smokeless tobacco use and cancers of the cheek and gums. Tobacco smoking is one of the strongest risk factors for oral cancers.Įvidence for snus leading to oral cancers is mixed. They also suggested that the increased risk of pancreatic cancer in tobacco smokers is related to the carcinogens involved with combustion. The 2017 study authors noted that their findings may be related to the lower nitrosamine levels in Swedish snus than in tobacco smoke. This study concluded that the data didn’t support any relationship between snus use and risk of pancreatic cancer in men. This included nonusers and users of snus. The most recent and largest study, reported in 2017, involved a large sample of 424,152 males in Sweden. The study concluded that use of Swedish snus should considered a possible risk factor for pancreatic cancer. Two other studies found no association.Ī 2007 study of Swedish construction workers who used snus and who hadn’t previously smoked found an increased risk of pancreatic cancer. Two studies that included snus specifically found a moderate risk increase. The increased risk for former smokers was 20 percent.ĭoes the risk remain the same with smokeless tobacco? The results aren’t clear-cut. A meta-analysis of 82 different studies found that the increased risk of pancreatic cancer for current smokers was 74 percent. Smoking is known to be a high risk factor for pancreatic cancer. According to a 2003 review in the BMJ journal Tobacco Control, 40 percent of males smoked daily in 1976, compared with 15 percent in 2002.Īt the same time, the researchers found that there have been reductions in lung cancer, cardiovascular disease, and deaths from other causes in Sweden. Specifically, the smoking rate dropped dramatically in Sweden as more men switched to snus use. They point to the public health benefits of snus use in Sweden. Plus, snus advocates say, it helps people stop smoking. So some of the worst effects of smoking aren’t present. The snus tobacco isn’t burned, and no smoke is inhaled. There’s a concern that snus can be a “gateway” to cigarette smoking, by hooking young people on nicotine.īut advocates of snus claim that snus is less harmful than inhaling nicotine, even though it’s addictive. The European Union has banned its sale (except for in Sweden) because of the known addictive and harmful effects of nicotine.
