A new study suggests that smokeless tobacco may increase the risk of heart attack and stroke. This is contrary to the belief that smokeless products, like snus, are safer. After analysing the results of several studies, researchers found that people who use smokeless tobacco products are more likely to develop or die from a heart attack or stroke. Smokeless tobacco caused 0.5 per cent of all heart attacks in the United States and 5.6 per cent in Sweden. The products were also the cause of 1.7 per cent of stroke deaths in the United States and 5.4 per cent in Sweden. Scientists hope to to confirm the correlation and call more attention to the area for the benefit of the public’s health.
