Sweden on track to be Europe's first smoke-free nation as cigarette consumption declines.

Sweden, which has the lowest rate of smoking in the European Union, is close to declaring itself "smoke-free" with fewer than 5% daily smokers in the population. The country has gone further than most to stamp out cigarettes, and says it's resulted in a range of health benefits, including a relatively low rate of lung cancer. Many experts give credit to decades of anti-smoking campaigns and legislation, while others point to the prevalence of "snus," a smokeless tobacco product that is banned elsewhere in the EU but is marketed in Sweden as an alternative to cigarettes.
