Relative risks were generally higher among women than men. Conclusions Smoking only about one cigarette per day carries a risk of developing coronary heart disease and stroke much greater than expected: around half that for people who smoke 20 per day.

Even if you smoke only occasionally, you are still exposed to long-term risks. As well as lung cancer, there are at least 13 other cancers linked with smoking. Smoking damages DNA in cells, including in key genes that protect you against cancer.
Background: Heavy smokers (those who smoke greater than or equal to 25 or more cigarettes a day) are a subgroup who place themselves and others at risk for harmful health consequences and also are those least likely to achieve cessation.

“And since people start out with millions of alveoli, it can take 15 or 20 years to lose enough of them to really become obvious. But once you develop something like chronic obstructive pulmonary disease (COPD), there's no going back. Once you get to that point, you're never going to get off the oxygen tank.”
John Everett Koop smoked three packs of cigarettes a day, developing a chronic cough that alarmed his wife. She shared her concerns with her son during one of his visits home from college. Koop agreed with her, but doubted that his father could muster the determination to quit.

He added: "There is a population of cells that, kind of, magically replenish the lining of the airways. "One of the remarkable things was patients who had quit, even after 40 years of smoking, had regeneration of cells that were totally unscathed by the exposure to tobacco."
After 15 years of having quit smoking, the likelihood of developing coronary heart disease is the equivalent of a non-smoker. Similarly, the risk of developing pancreatic cancer has reduced to the same level as a non-smoker.
