Snus (Swedish smokeless tobacco) use and risk of stroke: pooled analyses of incidence and survival

Abstract

Background. Snus is a moist smokeless tobacco product with high nicotine content. Its use has a short-term effect on the cardiovascular system, but the relationship between snus use and stroke is unclear.

Smokeless tobacco (snus) is associated with an increased risk of type 2 diabetes: results from five pooled cohorts

“…Our findings indicate that high consumption of snus increases the risk of type 2 diabetes. This is in contrast to findings for cardiovascular disease as well as cancer . The diabetes‐promoting effect of cigarettes and snus is hence likely to be mediated by nicotine, whereas the tobacco‐related risks of cardiovascular disease and cancer may be due to other components of cigarette smoke.…”

Use of moist smokeless tobacco (snus) and the risk of development of alcohol dependence: A cohort study in a middle-aged population in Sweden

“…In contrast, for non-smoked tobacco in the form of moist oral tobacco, snus, there is little scientific evidence for any risk of cancer, myocardial infarction, or stroke, although there are some indications of a slightly increased risk of fatal myocardial infarction (Hansson et al, 2012), fatal stroke (Hansson et al, 2012(Hansson et al, , 2014 and, for pregnant women, of preterm birth and stillbirth (Wikström et al, 2010). Nicotine in itself has previously been claimed by some researchers not to be harmful (Fagerström and Bridgman, 2014), and it has even been suggested to be comparable to coffee with respect to health effects (Phillips and Heavner, 2009).…”

Smokeless Tobacco - Health Hazards or Less Harm?

“…There was no associations between snus use and risk of stroke overall, HR 1.04 (95% CI 0.92-1.17) or any of its subtypes. The OR of 28-day fatality was 1.42 (95% CI 0.99-2.04) amongst users of snus who had suffered a stroke, and the HR of death during total followup was 1.32 (95% CI 1.08-1.61) [43]. Again, confounders cannot be ruled out.…”
