The Adverse Effects of e-Cigarettes on Oral Microbiome.
Dr. Purnima S. Kumar uses clinical skills and training to research ways to promote human microbiome health. She questions e-cigarette safety and ads.

Dr. Purnima S. Kumar is a periodontics professor at the University of Michigan, using her clinical skills and training to research numerous ways in which the human microbiome promotes health. She firmly believes in the complex relationship between oral health and systemic diseases, and that only through collaboration between physicians and dentists in identifying high-risk individuals and providing comprehensive care can global health be achieved. Her work on the impact of electronic cigarettes is extensive, including partnering with the American Dental Association to create public service ads on the health effects of using e-cigarettes and providing testimony to the FDA on the adverse effects of oral e-cigarette use. She is also a co-author of a study published in May 2020 in Science Advances, titled "Adverse effects of electronic cigarettes on the non-diseased oral microbiome," which addressed the lack of knowledge on the impact of e-cigarettes on the oral ecosystem despite their presence in the US market since 2009.


According to their knowledge, this investigation has provided some of the earliest empirical evidence documenting the impact of e-cigarette use on the oral microbiome and is beginning to explore potential mechanisms supporting this shift.


This study raises questions about the safety of e-cigarettes and the harm reduction claims made by advertising campaigns.


In February 2020, she published an article titled "Living Under the Cloud" in the Journal of the American Dental Association, where she highlighted that while there are existing studies on the health effects of electronic cigarettes, information on its impact on oral health such as periodontal disease, tooth decay, or oral cancer is limited.

EU Tobacco Tax Reform Targets November Push as Sweden Holds Nicotine-Pouch Minimum at €20 per Kilogram
EU Tobacco Tax Reform Targets November Push as Sweden Holds Nicotine-Pouch Minimum at €20 per Kilogram
The Irish presidency of the Council of the European Union is using bilateral talks to push the bloc’s Tobacco Taxation Directive toward a political agreement in November. According to Law360, citing an EU official, Sweden is unwilling to accept a minimum excise threshold above €20 per kilogram for nicotine pouches. Council negotiations have already lowered the European Commission’s original proposal, but a May 2026 presidency compromise still set the minimum at 10% of the tax-inclusive retail price or €30 per kilogram in 2028-29, with higher levels later.

Special Report | Vape bans and tougher rules: the South Caucasus takes different paths
Special Report | Vape bans and tougher rules: the South Caucasus takes different paths
Azerbaijan's sweeping e-cigarette ban has raised concerns over enforcement errors and the emergence of illicit sales, while neighboring Armenia is tightening technical rules and preparing higher excise taxes. Georgia, meanwhile, has resisted calls for broader vape restrictions and introduced preferential taxes for some domestically produced cigarettes. The divergent approaches across the South Caucasus highlight a regional policy dilemma: how to curb nicotine use and protect public health without encouraging black markets or creating unintended economic consequences for businesses and consumers.

Sweden Threatens EU Tobacco Tax Deal as Nicotine Pouch Duty Dispute Looms Over November 9 Meeting
Sweden Threatens EU Tobacco Tax Deal as Nicotine Pouch Duty Dispute Looms Over November 9 Meeting
Sweden is expected to oppose a European Union proposal to raise minimum tobacco excise duties, Law360 reported on October 26, 2026, citing an EU official. A provisional Council agenda dated October 23 confirms that the tobacco taxation package is scheduled for discussion at the November 9 finance ministers' meeting, where member states will seek a general approach. The proposed reforms would raise minimum taxes on conventional tobacco products and establish EU-wide excise rules for vaping liquids, heated tobacco and nicotine pouches. Sweden supports harmonising tobacco taxation rules but objects to requiring nicotine pouches to bear the same minimum tax burden as certain smoking tobacco products. As EU indirect tax legislation requires unanimous Council approval, Swedish opposition could block the proposal in its current form.

Product | OXVA Introduces XLIM PRO 4 With Liquid-Level Anti-Burn Technology and Dedicated Pods
Vaping brand OXVA introduced the XLIM PRO 4 refillable pod system in October 2026, featuring Anti-Burn Tech (ABT) based on smart e-liquid-level detection. The system can issue refill alerts and stop power output when e-liquid levels become too low. ABT requires the XLIM PRO 4 device and a dedicated XLIM ABT cartridge. Standard XLIM pods remain compatible but do not support ABT protection. OXVA previously introduced temperature-based anti-burn technology in the XLIM Pro 2 DNA, developed with Evolv. The new device features a 1,800mAh battery, 5–30W output and a 0.98-inch HD color screen. OXVA's official store lists the device at $37.90 and dedicated ABT replacement cartridges at $12.99. Independent testing confirmed the low-liquid protection response but recorded varying cartridge lifespans.
