Summary
Brief summary (as posted)
This clinical trial investigates the effects of switching from smoking regular cigarettes to electronic cigarettes (e-cigarettes) among older adult smokers at high risk for lung cancer. E-cigarettes use heated vapor to deliver nicotine. Information gained from this trial may help inform regulators of the potential risks and benefits of switching smokers at high risk for lung cancer to electronic cigarettes. This research also may help inform the Food and Drug Administration (FDA) how best to regulate e-cigarettes with the goal of improving public health.
