New Guidelines Explore E-Cigarettes as a Tool to Help Adults Quit Smoking

New 2026 clinical guidance recommends discussing nicotine e-cigarettes alongside established smoking cessation treatments for adults who smoke.

A new set of clinical recommendations is putting e-cigarettes more firmly into the conversation about smoking cessation. Experts from the Society for Research on Nicotine and Tobacco have published guidance for US clinicians on how nicotine e-cigarettes may be discussed with adults who want to quit cigarettes.

The recommendations, published in JAMA on July 30, 2026, do not describe vaping as risk-free. Instead, they focus on the potential harm reduction benefits of replacing combustible cigarettes with e-cigarettes, particularly for adults who have struggled to quit using established treatments.

What do the new smoking cessation guidelines say?

The central recommendation is that clinicians should include nicotine e-cigarettes when discussing evidence-based options for smoking cessation. The guidance emphasizes shared decision-making, meaning patients and healthcare professionals should consider the potential benefits, risks, preferences and practical circumstances before selecting a quit strategy.

Traditional smoking cessation options include nicotine replacement therapy, such as patches, gum and nasal sprays, as well as prescription medicines such as varenicline and bupropion. The new recommendations do not suggest abandoning these treatments. Instead, e-cigarettes are presented as another option that may be considered for some adults who smoke.

This distinction is important. The goal is not to encourage people who do not smoke to begin vaping. The focus is on adults who currently smoke cigarettes and are trying to stop.

Why are e-cigarettes being considered?

Combustible cigarettes expose users to thousands of chemicals created during the burning of tobacco. Many of these substances contribute to serious diseases, including cancer, cardiovascular disease and respiratory illness.

E-cigarettes do not burn tobacco in the same way. Consequently, switching completely from cigarettes to vaping can substantially reduce exposure to many harmful chemicals associated with combustible tobacco.

The new JAMA communication states that nicotine e-cigarettes are less harmful than cigarettes and have demonstrated greater effectiveness for smoking cessation than FDA-approved nicotine replacement therapies in the evidence reviewed by the authors.

A related JAMA commentary also points to evidence from randomized clinical trials and systematic reviews supporting the effectiveness of nicotine e-cigarettes for helping people quit smoking.

However, lower risk does not mean no risk. Nicotine remains addictive, and vaping can lead to continued nicotine dependence. The long-term health effects of e-cigarette use also remain an important area of research.

Complete switching matters

One of the most important points in the recommendations is the distinction between replacing cigarettes and simply adding vaping to existing smoking.

For people who choose e-cigarettes as a quitting tool, the guidance encourages them to transition away from combustible cigarettes rather than maintain long-term dual use.

This is significant because continuing to smoke while also vaping may limit the potential health benefits of moving away from combustible tobacco.

The recommendations encourage clinicians to help patients develop a clear plan for stopping cigarette use. Behavioral support can also be incorporated into the plan to improve the chances of long-term success.

How should e-cigarettes be used as part of a quit attempt?

The expert recommendations emphasize several practical principles.

First, clinicians should discuss e-cigarettes alongside other established smoking cessation treatments. Patients should understand that different approaches work for different people.

Second, anyone choosing an e-cigarette strategy should aim to replace cigarettes rather than simply supplement cigarette smoking.

Third, behavioral counseling should be considered as part of the quit attempt. Counseling can help people identify triggers, prepare for cravings, establish a quit date and manage situations that could lead to relapse.

Finally, once someone has successfully stopped smoking cigarettes, clinicians can discuss whether reducing nicotine exposure from vaping is appropriate.

The overarching priority remains complete abstinence from cigarettes.

E-cigarettes are not risk-free

It is important not to interpret the new recommendations as saying that vaping is harmless.

Nicotine can cause dependence, and e-cigarette aerosols can contain potentially harmful substances. In addition, people who have never smoked should not start using nicotine e-cigarettes simply because they are less harmful than cigarettes.

The evidence also continues to develop. The 2020 US Preventive Services Task Force recommendation found insufficient evidence at that time to determine the overall balance of benefits and harms of e-cigarettes for smoking cessation. It instead recommended behavioral interventions and FDA-approved pharmacotherapy for nonpregnant adults who smoke.

The newer 2026 JAMA recommendations reflect more recent evidence and are specifically designed to help clinicians discuss nicotine e-cigarettes with adults who currently smoke. They should therefore be understood as an evolving part of the smoking cessation evidence base rather than as proof that vaping is universally safe.

What about people who are pregnant?

The new recommendations are specifically aimed at US-based clinicians discussing smoking cessation with adult patients. They should not be interpreted as a general recommendation for pregnant people to use e-cigarettes.

Smoking during pregnancy carries substantial health risks, and decisions about smoking cessation treatment during pregnancy require individualized medical advice.

Existing guidance has highlighted the limited evidence surrounding pharmacological smoking cessation treatments during pregnancy and the need for clinical assessment.

Anyone who is pregnant and wants to stop smoking should speak with a qualified healthcare professional about the safest approach.

How does this compare with UK guidance?

The regulatory situation differs between the United States and the United Kingdom.

UK guidance from the National Institute for Health and Care Excellence says that, as of its February 2025 update, nicotine-containing e-cigarettes were not licensed by the Medicines and Healthcare products Regulatory Agency as medicines for stopping smoking. NICE guidance also distinguishes medicinally licensed nicotine products from commercially available nicotine e-cigarettes.

This means readers should be cautious when applying US clinical recommendations to healthcare decisions in the UK. Product regulation, licensing and clinical guidance can vary between countries.

What does this mean for smokers trying to quit?

The most practical message is that there is no single smoking cessation method that works for everyone.

Some people successfully quit with nicotine patches or gum. Others may benefit from prescription medication, counseling or a combination of treatments. The new recommendations argue that nicotine e-cigarettes should also be part of the conversation for adults who smoke, particularly when conventional approaches have not worked or are not acceptable to the individual.

For someone who currently smokes, completely switching from cigarettes to e-cigarettes may reduce exposure to the toxic substances generated by burning tobacco. But the ultimate objective should remain stopping cigarette smoking and, where appropriate, eventually reducing dependence on nicotine altogether.

The guidance therefore represents a harm reduction approach rather than an endorsement of vaping as harmless.

The bottom line

New 2026 recommendations from the Society for Research on Nicotine and Tobacco say clinicians should discuss nicotine e-cigarettes alongside other evidence-based smoking cessation options for adults who smoke.

The evidence reviewed by the authors suggests nicotine e-cigarettes can help some people quit cigarettes and may be more effective than traditional nicotine replacement therapy in certain comparisons.

At the same time, vaping carries risks, nicotine is addictive and long-term effects remain an important research question. The potential health benefit comes primarily from moving completely away from combustible cigarettes, not from using both products indefinitely.

Anyone considering e-cigarettes as a smoking cessation strategy should discuss the available options with a healthcare professional, particularly if they are pregnant, have underlying health conditions or take prescription medicines.
