Can E-Cigarettes Help You Quit Smoking?

Published: December 2016

Most researchers and public health professionals agree that e-cigarettes and other vaping devices are less harmful than smoked cigarettes, because they do not contain tobacco, the leading contributor to the majority of negative health effects associated with smoking. When used as a complete replacement, rather than in addition to cigarettes, they are a preferable alternative for smokers who haven’t had success with medically proven approaches.

But are they really a good option for smokers who want to cut down or quit smoking? Not necessarily. While a few studies have found that e-cigarettes can help reduce smoking, most show that e-cigarette use does not significantly reduce cigarette use, and several found that people who use e-cigarettes may be less likely to successfully quit smoking.

Overall, the limited research findings are inconclusive. A recent scientific review concluded that the data available on the role of e-cigarettes in smoking cessation are limited due to a small number of studies and a lack of quality data. Many studies are currently underway to help determine whether using e-cigarettes to quit or reduce smoking is a good choice.

What Should Cigarette Smokers Do Who Want to Cut Back or Quit?

Given the limited research regarding the effectiveness of e-cigarettes as a smoking cessation aid and the growing body of evidence regarding their risks, the safest approach is to talk to your doctor about proven and effective cessation techniques.

The U.S. Food and Drug Administration (FDA) has approved a variety of smoking cessation products and determined that they are safe and effective. These include certain prescription medications, as well as over-the-counter nicotine replacement therapies, such as skin patches, lozenges and gum. E-cigarettes have not been approved by the FDA for smoking cessation.
