Tobacco Use

Clinician-led interventions are proven treatments that can help smokers quit and reduce their risk for heart disease and stroke.

Tobacco Use and Heart Health

Tobacco smokers are at greater risk for diseases that affect the heart and blood vessels, including heart disease and stroke. Even people who smoke fewer than five cigarettes a day are at increased risk for these diseases. The risk increases with the number of cigarettes smoked per day and the number of years that smoking continues. Exposure to secondhand tobacco smoke also increases the risk for heart disease and stroke. People who already have heart disease are at especially high risk of adverse effects from breathing secondhand smoke and should avoid even brief exposures.

Studies have shown that comprehensive smoke-free laws that prohibit smoking in workplaces and public places like bars and restaurants help improve the health of workers and the general population, as well as eliminate involuntary secondhand smoke exposure. Smoke-free laws have been shown to substantially reduce heart attack hospitalizations among nonsmokers, prevent nonsmokers from starting to smoke, and motivate tobacco users to quit.

The damage to the heart and blood vessels from smoking can be repaired quickly for most smokers who quit. Even longtime smokers can see rapid health improvements when they quit. Within a year, heart attack risk drops dramatically. Within five years, most smokers cut their risk of stroke to nearly that of a nonsmoker. Quitting smoking is hard and may require several attempts. Clinician-led cessation counseling and medication are proven treatments that can help smokers quit. However, in 2015, only 57% of current smokers reported receiving advice to quit from a health professional, and only 29% used medication.
