Many Americans who’ve smoked cigarettes have been successful in their efforts to quit. But there’s some bad news for those who’ve settled for just cutting back: new evidence shows there’s no safe amount of smoking. One cigarette a day, or even less than that, still poses significant risks to your health.
A study conducted by NIH researchers of more than 290,000 adults between the ages of 59 and 82 found that those who reported smoking less than one cigarette per day, on average, for most of their lives were nine times more likely to die from lung cancer than those who never smoked. The outlook was even worse for those who smoked between one and 10 cigarettes a day. Compared to never-smokers, they faced a 12 times greater risk of dying from lung cancer and 1½ times greater risk of dying of cardiovascular disease.
