Potential Risks of Long-Term E-Cigarette Use

Potential Risks of Long-Term E-Cigarette Use
Studies on the potential dangers of long-term e-cigarette use vary, with some suggesting a 5% risk of potential harm.

Some studies have not quantified the potential risks of long-term use of electronic cigarettes. Others believe that while the dangers of e-cigarettes are 95% lower than traditional cigarettes, the remaining 5% represents a conservative estimate of potential risks from flavorings and ingredients over the long term. Some still insist that it is not possible to draw definitive conclusions today. According to one study, most tested models showed low levels of toxicity, and therefore do not pose a danger to users.


However, the author explains that this is not a reliable measure as the number of models and amounts of e-liquid in the market continue to increase without testing [4]. Ultimately, for the World Health Organization, the toxicity of e-cigarettes may be lower than tobacco, but according to them, there is no evidence to suggest the effectiveness of e-cigarettes in quitting smoking [5]. The view that conflicts with the Cochrane organization's point of view is that e-cigarettes are almost twice as effective as other nicotine replacement products (patches, gum, etc.) in quitting smoking.


In the end, the results from these different studies may vary and have different interpretations, but almost all the research agrees on one point: the current results are encouraging.

Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
Pennsylvania Vape Directory Law Survives Court Challenge From Nova Distro and Others Amid Similar Rulings Across States
A U.S. federal court upheld Pennsylvania's vape directory law on October 14, rejecting a challenge brought by Nova Distro, 101 Distributors and companies operating Tobacco Hut retail stores. Court records show that vaping accounts for about 60% of Tobacco Hut's profits and that the chain held approximately $2 million in inventory potentially subject to seizure under the law as of June 2. Pennsylvania began enforcement on October 19. The ruling follows similar appellate decisions in other states, even as new research shows that unlisted vaping products continue to account for substantial sales in states with established directories.

On-Site Report | After FDA Announces Review of PMTA Framework, CTP Director Details Reform Priorities
FDA CTP Director Bret Koplow used his FDLI keynote in Washington to outline how the agency is rethinking the PMTA framework. He discussed category-specific review, nicotine pouch and sPMTA pilots, AI-assisted review, a 70% reduction in pending applications, and a major staffing constraint: CTP currently has only nine scientific review teams. He also reaffirmed tobacco harm reduction while stressing youth protection, flavored products, risk communication, and the challenge of unauthorized e-cigarettes.

NAS 2026 | Cliff Douglas: Risk Continuum Should Play a Central Role in Tobacco Policy
Cliff Douglas, a veteran U.S. tobacco-control and public health policy figure, told NAS 2026 that the “continuum of risk” should play a central role in tobacco policy. He called for clearer market pathways, stronger risk communication, differentiated regulation and enforcement, and said possible FDA reforms to PMTA reviews could be a “welcome correction” if they create a more efficient, predictable route for scientifically substantiated lower-risk products.

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.

U.S. Health Groups Seek to Overturn FDA Enforcement Discretion for Pending PMTAs as Altria's Helix, NJOY and AVM Move to Intervene
American Vapor Manufacturers (AVM) and Altria subsidiaries Helix Innovations and NJOY filed separate motions on October 7, 2026, seeking to intervene on the FDA's side in a lawsuit challenging its enforcement guidance for certain e-cigarette and nicotine pouch products with pending premarket tobacco product applications (PMTAs). Seven public health and tobacco-control organizations, including the Campaign for Tobacco-Free Kids, sued the agency in July to overturn the policy. AVM argues that vacating the guidance could disrupt orders, inventory, retail distribution and investments in regulatory submissions.
