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.

Philippines Mandates Safety Certification for Nicotine Pouches, Gives Industry 12 Months to Comply
Philippines Mandates Safety Certification for Nicotine Pouches, Gives Industry 12 Months to Comply
The Philippines Department of Trade and Industry has placed nicotine pouches under mandatory product certification through Department Administrative Order No. 26-07, Series of 2026. Nicotine pouches must obtain a Philippine Standard, or PS, license before they can be manufactured, imported, packed, distributed or sold in the country. The regime requires testing for nicotine content, pH and water activity, while packaging must disclose nicotine strength, ingredients, allergens, batch information, the PS certification mark and prescribed health warnings. Existing market participants have a 12-month transition period to comply.

Texas Extends Tobacco Tax Interpretation to a 6-Methylnicotine Product, Citing VELO Ruling
Texas Extends Tobacco Tax Interpretation to a 6-Methylnicotine Product, Citing VELO Ruling
The Texas Comptroller of Public Accounts ruled in September 2026 that a combustible product made with non-tobacco plant material and 6-methylnicotine (6-MN), a synthetic nicotine analog, qualifies as a taxable tobacco product. The applicant said the product contained neither tobacco leaf nor measurable conventional nicotine. The determination applies reasoning from a May Texas Supreme Court decision involving VELO nicotine pouches, finding that the plant material and 6-MN together perform the functions of tobacco in a conventional smoking product. The ruling carries applicable tax, licensing and reporting obligations but is limited to the facts submitted by the taxpayer. It does not establish a blanket tax classification for all 6-MN products or extend the same conclusion to e-cigarettes.

FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
The U.S. Food and Drug Administration has revised the rules under Import Alert 98-07 to incorporate its May 2026 enforcement-priority policy for certain electronic nicotine delivery systems marketed without premarket authorization. The alert continues to allow detention without physical examination, or DWPE, for ENDS lacking required marketing authorization, while directing field divisions to apply the May risk-based framework. When necessary, detention or refusal decisions must also undergo review by the FDA's Center for Tobacco Products. Products including PACHA and Vuse Pro have already emerged as industry examples of the May policy, although enforcement discretion does not constitute FDA marketing authorization.

JAMA Study: U.S. Vape Directories Fail to Sustainably Curb Unlisted Sales as Product Shifts May Redistribute Brand Share 2Firsts Recommended
A study by CDC Foundation researchers found no sustained decline in e-cigarette sales across Alabama, Oklahoma and Louisiana, the first three U.S. states to implement e-cigarette directory laws. Louisiana initially saw a significant sales decline, followed by a rebound and a persistent reduction in product availability. Sales also shifted from nontobacco-flavored disposables toward prefilled cartridges, with Vuse Alto driving much of the increase in menthol cartridges. By April 2025, unlisted products still accounted for more than half of e-cigarette nicotine sales in all three states.
