New Study on Dual Use of Cigarettes and E-Cigarettes.

New Study on Dual Use of Cigarettes and E-Cigarettes.
A new study published in the Addiction journal found that dual users of e-cigarettes and combustible cigarettes have lower levels of toxic chemicals.

A new study published in the scientific journal Addiction suggests that individuals who use nicotine vapor products or electronic cigarettes while trying to quit smoking have lower levels of toxic chemicals in their bodies. The study analyzed the biomarkers of nearly 1,300 individuals who either smoked traditional cigarettes, used e-cigarettes, or used both in what is known as dual use. The researchers found that compared to traditional cigarette smokers, those who used both products had lower levels of toxic chemicals such as carbon monoxide in their bodies. This contradicts previous beliefs that using e-cigarettes as a smoking cessation method would lead to increased smoking and greater exposure to harmful chemicals from both traditional and electronic cigarettes.


What is "dual use"? Dual use refers to continuing to smoke traditional cigarettes even after starting to use electronic cigarettes. This has become a common practice among those attempting to quit smoking using electronic cigarettes. Many opponents of electronic cigarettes point to the prevalence of dual use as evidence that electronic cigarettes do not help people quit smoking, but rather encourage the development of another harmful habit: vaping.


It cannot be denied that many people are smoking traditional cigarettes and using e-cigarettes simultaneously. Numerous studies in the past two years have repeatedly found that people attempting to quit smoking by using e-cigarettes continue to smoke traditional cigarettes. Additionally, researchers pointed out that the success rate of dual users quitting either traditional cigarettes or e-cigarettes is not higher than those who use nicotine replacement therapy.


Many studies over the past decade have consistently shown that electronic cigarette users frequently engage in dual use, meaning they continue to smoke traditional tobacco cigarettes while using e-cigarettes. This is the case in the United States, United Kingdom, and European Union. For example, American smokers report that e-cigarette use has remained unchanged for three consecutive years, dropping only slightly from 29.8% in 2015 to 27.7% in 2018.


A similar report exists in the United Kingdom as well. A study revealed that the rate of dual use of electronic and traditional cigarettes is higher among teenagers who only use e-cigarettes, despite them being the largest group in the survey. The research also showed that young people who started with traditional cigarettes are more likely to continue to smoke them even after starting to use e-cigarettes.


Many people from different countries and backgrounds, regardless of race and gender, engage in dual use behavior, which seemed to reinforce the belief that e-cigarettes are not helpful for quitting smoking. However, this new study overturns this assumption by stating that dual use is only a transition, not a permanent one.


Is Dual Use of Tobacco and E-cigarettes Risky? Many studies have hinted at the potential danger of using both tobacco and e-cigarettes simultaneously. For instance, one study suggests that the likelihood of developing cardiovascular diseases is higher in individuals who use both products compared to those who only use e-cigarettes but lower than those who only smoke tobacco. However, new evidence from a recent study reveals the opposite.


A new study has examined the levels of carbon monoxide in the breath of cigarette smokers, e-cigarette users and those who use both. The study found that the levels of carbon monoxide in the bodies of those who only use e-cigarettes were lower than those who smoke cigarettes or use both. However, compared to those who only smoke cigarettes, those who use both also had lower levels of carbon monoxide in their bodies.


Another study found that dual users were more likely to quit smoking after a period of time, rather than returning to using only one type or quitting altogether. However, the study also found that, aside from dual use, there were other factors that caused them to stop smoking, unrelated to whether they smoked cigarettes. This study also suggests that those who smoke cigarettes and use electronic cigarettes usually return to only smoking cigarettes.


Can e-cigarettes help you quit smoking? Despite new research, many public health organizations and policymakers are unlikely to change their views on e-cigarettes, at least in America. However, despite the risks, countries like the UK have already adopted e-cigarettes as another tool to help people quit more harmful smoking habits.


Although this new study does offer new evidence in support of the notion that dual smoking is not as harmful as smoking cigarettes alone, it is not definitive proof. Other factors aside from using electronic cigarettes or vaping are relevant in determining whether an individual can successfully quit smoking. However, this study does indicate that going through a transitional period during the process of quitting smoking is harmless.

GSTHR Estimates 200 Million People Use Non-Combustible Nicotine Products as 28 Countries Show Rising Use Alongside Falling Smoking Rates
GSTHR Estimates 200 Million People Use Non-Combustible Nicotine Products as 28 Countries Show Rising Use Alongside Falling Smoking Rates
The Global State of Tobacco Harm Reduction, a project operated by Knowledge·Action·Change, estimates that about 200 million people worldwide use non-combustible nicotine products including vapes, heated tobacco, nicotine pouches and snus. Its 2026 report says use of these products rose alongside declining smoking rates in 28 countries it analyzed. The data do not establish that all 200 million users have quit smoking, nor do they prove a direct causal relationship. GSTHR also says regulatory restrictions on the products continue to expand in many markets.

JAMA Issues First U.S. Clinical Guidance on Vaping for Smoking Cessation, Urging Complete Switch From Cigarettes
JAMA Issues First U.S. Clinical Guidance on Vaping for Smoking Cessation, Urging Complete Switch From Cigarettes
JAMA has published a Special Communication offering systematic recommendations for U.S.-based clinicians on the use of nicotine e-cigarettes in adult smoking cessation. Developed by the Harm Reduction Workgroup of the Society for Research on Nicotine and Tobacco’s Treatment Research Network, the paper recommends including e-cigarettes alongside FDA-approved cessation medications in risk-benefit discussions. It cites high-certainty evidence that nicotine e-cigarettes achieve higher quit rates than nicotine replacement therapy and evidence suggesting efficacy comparable to highly effective medications such as varenicline and cytisine. For adults who choose vaping to quit, the authors recommend FDA-authorized products, sufficient nicotine delivery and a rapid, complete transition away from cigarettes rather than prolonged dual use.

U.S. Ninth Circuit Upholds FDA Denial of MH Global’s Flavored Vape PMTA Applications
U.S. Ninth Circuit Upholds FDA Denial of MH Global’s Flavored Vape PMTA Applications
The U.S. Court of Appeals for the Ninth Circuit upheld the FDA’s denial of MH Global LLC’s applications to market flavored electronic nicotine delivery systems (ENDS). The court ruled that FDA’s comparative-efficacy framework, which requires applicants to show that flavored products provide greater cessation or switching benefits than tobacco-flavored alternatives, is consistent with the Tobacco Control Act’s “appropriate for the protection of the public health” standard. The court also found that FDA was not required to establish the framework through notice-and-comment rulemaking.

Couche-Tard Posts Double-Digit U.S. Same-Store Growth in Other Nicotine Products, Led by Pouches
Alimentation Couche-Tard said U.S. same-store sales in its “other nicotine products” category grew at a double-digit rate in the first quarter of fiscal 2027, led by nicotine pouches, while overall U.S. same-store merchandise revenues increased 1.7%. The company also said its Canadian nicotine business continued to face regulatory pressure and illicit-market headwinds. The U.S. performance coincides with Couche-Tard's participation in efforts to reopen Canadian convenience-store access to authorized nicotine pouches, though the company has not established a direct causal link between the two.
