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.

German Tobacco Tax Revenue Falls 10.8% Through August as Tax-Paid Cigarette Volume Drops 12.6%
German Tobacco Tax Revenue Falls 10.8% Through August as Tax-Paid Cigarette Volume Drops 12.6%
Germany collected €9.789 billion in total tobacco tax revenue from January through August 2026, down 10.8% from a year earlier, according to the Federal Ministry of Finance. Germany's tobacco tax base covers not only cigarettes and fine-cut tobacco but also heated tobacco and vaping liquids taxed as tobacco substitutes. The German Association of the Tobacco Industry and Novel Products, or BVTE, citing federal statistical data, said tax-paid cigarette volume fell 12.6% to 40.6 billion sticks. BVTE is using the latest figures to argue against further tax increases planned from 2027 through 2030, while Germany's parliament is scheduled to hold a first reading of the bill on September 24.

Smoore Seeks to Toss CCELL Price-Fixing Claim as Court Weighs Vertical Distribution Versus Horizontal Conspiracy
Smoore Seeks to Toss CCELL Price-Fixing Claim as Court Weighs Vertical Distribution Versus Horizontal Conspiracy
Smoore and four authorized U.S. CCELL distributors are asking a California federal court to permanently dismiss a core antitrust claim brought by direct purchasers. Plaintiffs allege that Smoore coordinated minimum wholesale prices, customer allocation and limits on price competition among distributors, amounting to a per se unlawful horizontal conspiracy. The defendants say the alleged conduct reflects ordinary vertical relationships between a manufacturer and its distributors. The court previously dismissed a similar claim, and the latest dispute centers on whether the second amended complaint adds sufficient facts to establish a horizontal agreement.

Philip Morris Malaysia Again Meets Religious Authority Over Cigarette Alternatives as Perlis Mufti Responds on Halal Criteria
Philip Morris Malaysia Again Meets Religious Authority Over Cigarette Alternatives as Perlis Mufti Responds on Halal Criteria
Philip Morris Malaysia Managing Director Naeem Shahab Khan met Perlis Mufti Mohd Asri Zainul Abidin on September 17 and presented the company's shift from conventional cigarettes toward alternative products. The mufti said a product could be considered halal if it is clean, its side effects are not harmful or can be controlled, and it does not involve excessive waste. His remarks did not mention IQOS or any other specific PMI product and did not amount to a new product-specific religious ruling. It was at least the second publicly reported engagement between Philip Morris Malaysia and a Malaysian religious institution over cigarette alternatives within six months.

FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
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.
