Trying to quit smoking? Experts urge recommendation of e-cigs for adult cigarette smokers

E-cigarettes aren’t safe, but they’re ‘dramatically safer’ than smoking. Citing strong evidence for harm reduction, Brown experts join co-authors for a new SRNT paper that advises healthcare providers discuss vaping with adult smokers struggling to quit.

Cigarette smoking remains the leading cause of preventable disease and death in the United States and one of the leading causes of death globally. Although 68% of people who smoke say they want to quit, only 10% of those who make a quit attempt remain smoke-free one year later.

There are several FDA-approved smoking cessation medications, including nicotine gum, lozenges, nasal sprays and patches. While the nicotine-based products can be effective, they deliver relatively low levels of nicotine and fail to fully replace the nicotine smokers obtain from cigarettes.

A new position paper by a working group from the Treatment Research Network of the Society for Research on Nicotine and Tobacco (SRNT) seeks to address this issue by recommending that clinicians include e-cigarettes in their discussions with adult smokers who are trying to quit. The paper summarizes the latest evidence and offers practical guidance to health care providers for discussing the risks and benefits of e-cigarettes with their patients.

“Are e-cigarettes safe? No, they’re not. Are they safer than cigarettes? Dramatically safer,” said one of the paper’s authors, Dr. Jasjit S. Ahluwalia, who is professor of behavioral and social sciences and medicine at Brown University and a member and former board member of the SRNT. “Many randomized clinical trials and systemic reviews—including the Cochrane ‘living’ review, which is updated as new evidence is published—report well-established evidence that e-cigarettes are associated with higher quit rates than other nicotine replacement therapies.”

Ahluwalia and co-authors, including Cara Murphy, assistant professor of behavioral and social sciences, stress that while e-cigarettes are not an FDA-approved smoking cessation medication, some have been authorized by the FDA’s Center for Tobacco Products as “appropriate for the protection of public health.”

“Evidence from clinical trials involving thousands of participants consistently shows that e-cigarettes can help people quit smoking more effectively than traditional nicotine replacement therapies, such as nicotine patches or gum,” Murphy said. “Importantly, those trials provide participants with clear guidance on how to completely transition away from cigarettes.”

“The concept is not that e-cigarettes are safe, but that they are harm reduction tools in the same way that one might use methadone for opioid addiction,” Ahluwalia said. “Harm reduction minimizes the dangers of smoking rather than focusing on abstinence as the only viable option.”

The paper's authors note that public misperceptions about e-cigarettes have increased in recent years, despite the growing evidence that completely switching from combustible cigarettes to e-cigarettes substantially reduces exposure to the roughly 7,000 chemicals produced by a single burning cigarette – at least 69 of which are recognized as cancer-causing agents by the American Lung Association. By contrast, the liquids used in e-cigarettes generally consist of about five core ingredients: propylene glycol, vegetable glycerin, nicotine, water and flavoring. 

“Combustion is the primary driver of tobacco-related harm, making combustible cigarettes the most harmful to health,” the authors write. “By comparison, completely substituting e-cigarettes for cigarettes is associated with marked reduction in toxicant exposure and downstream harm.”

With the goal of ensuring patients receive accurate information on e-cigarettes, the authors offer the following recommendations to clinicians:

  • Include e-cigarettes on the list of options to support smoking cessation, alongside FDA–approved medications such as nicotine replacement therapies, varenicline and bupropion.
  • Assess and correct misperceptions regarding the harm and safety of cigarettes vs e-cigarettes.
  • Ask key questions to guide the decision-making process. For example: What are the patient’s goals? How does the patient feel about using an alternative nicotine product to quit smoking? What part of quitting is most challenging to them? Do they have support from family and friends to quit smoking? What methods have they tried before? Which treatment options do patients find most appealing? What are their major concerns with the options discussed?
  •  Finally, if after a risk-benefit conversation the patient prefers to try an e-cigarette to quit smoking, they should be supported in doing so. Patients should not be required to first try or “fail” an FDA-approved medication before using an e-cigarette for cessation because supporting cigarette cessation is the primary goal.

The authors emphasize that these recommendations apply only to adults who currently smoke cigarettes—not to young people, young adults under 21 or individuals who have never used tobacco or nicotine products.

“Many people trying to quit have received little or no guidance from health care providers about how to use e-cigarettes effectively to help them quit smoking, and many have been discouraged from even considering them,” Murphy said. “We hope this article will help providers feel more confident discussing all evidence-based smoking cessation options with their patients so they can make informed decisions together.”
