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.

R.J. Reynolds Vapor Company Launches Flavored Vuse Pro Pods in U.S. Without FDA Marketing Authorization
R.J. Reynolds Vapor Company has begun selling four flavored Vuse Pro pods — Peach, Berry, Watermelon and Fresh Mint — in Ohio and selected other U.S. markets. According to the Vuse U.S. FAQ, Vuse Pro contains approximately 5.0% nicotine by weight, and Vuse Pro pre-filled pods are intended for use with Vuse Alto devices. Reynolds told 2Firsts that product labeling lists an e-liquid capacity of 2.0 mL per pod. The Vuse Alto Power Unit received FDA marketing authorization in 2024, while the new Vuse Pro pods themselves have not received marketing granted orders. The rollout follows the FDA’s May 2026 revision of enforcement priorities for certain unauthorized vaping products with qualifying pending applications.

UK Directors Banned After 352,688 Vapes Imported From China Were Misdeclared as Medical Nebulizers in £15 Million Tax Case

HMRC calculated nearly £15 million ($20.3 million) in unpaid VAT and customs duty, alongside about £437,000 in corporation tax. Two directors were disqualified for nine years. The case predates the UK's Vaping Products Duty, which will introduce vape-specific excise and duty-stamp requirements from October 2026.

Canada Considers Easing Pharmacy-Only Nicotine Pouch Sales Rules, Potentially Reopening Convenience Store Channel
Canada Considers Easing Pharmacy-Only Nicotine Pouch Sales Rules, Potentially Reopening Convenience Store Channel
Canada's federal government is considering changes to current restrictions on where nicotine pouches can be sold, potentially allowing authorized products to return to convenience stores and other general retail channels, although no decision has been made. Since 2024, emerging nicotine replacement therapy products such as nicotine pouches have been largely restricted to behind-the-counter pharmacy sales. Health Canada, meanwhile, continues to recall unauthorized and higher-strength nicotine pouches, indicating that the current discussion concerns retail access for authorized products rather than a broad relaxation of nicotine pouch regulation.
