Oral health: Vaping inflicts damage and can lead to ‘irreversible’ problems

A commentary published in the international open-access, peer-reviewed Harm Reduction Journal argues that randomized controlled trials remain central to evaluating smoking cessation efficacy but cannot alone capture real-world uptake, complete switching, longer-term use and population impact of non-combustible nicotine products such as e-cigarettes, heated tobacco and nicotine pouches. The authors frame impact as “reach × efficacy” and call for real-world evidence to complement RCTs. Three days after publication, the FDA authorized three JUUL2 products and highlighted complete switching among adult smokers in explaining its decision, providing a timely regulatory backdrop to the debate.

Philip Morris International’s second-quarter earnings call offered new detail on its smoke-free strategy. Management said it would increase U.S. investment behind nicotine pouch brand ZYN, keep IQOS focused on volume before stronger pricing, and use SENTIA, DELIA, LEVIA, VEEV and ZYN to manage tax and regulatory pressure across Japan and Europe. Analysts from Goldman Sachs, Morgan Stanley, UBS and other firms also pressed PMI on profitability, market share, cigarette resilience and the durability of its global transformation over coming quarters.

New Zealand Associate Health Minister Casey Costello said legal tobacco sales in the country have fallen by more than half over the past decade, with sales declining more than 20% in 2025 compared with the previous year. She warned that the decline may not fully reflect lower smoking rates, as increased availability of illicit cigarettes could also be contributing. The government said it would continue strengthening tobacco and vape retail enforcement while monitoring the impact of illicit tobacco on public health and tax revenue.

JT’s Ploom heated-tobacco volumes rose 43.5% in the first half of 2026, while combustibles still represented about 97% of its tobacco volume and remained the main earnings base. In Japan, reduced-risk products now account for 48.7% of industry shipments, shifting competition from category adoption towards brand share, pricing and consumer retention. JT’s results offer a revealing case of a traditional tobacco company pursuing a prolonged, dual-track transformation.

On July 23, 2026, the U.S. House of Representatives passed its version of the Fiscal Year 2027 National Defense Authorization Act (NDAA), which includes Section 707 provisions requiring the Department of Defense to evaluate tobacco use and nicotine alternatives among military personnel. The pilot program would examine products including vapes, nicotine pouches and heated tobacco products, primarily among active-duty service members who continue using combustible tobacco. The provision is a policy evaluation effort, not an authorization for military vaping promotion or a ban on vape products.

Philippine lawmakers are considering an overhaul of the country's vape excise-tax regime to eliminate the wide gap between taxes on nicotine salt and freebase nicotine liquids and reduce incentives for misdeclaration. House Bill 5364, filed by Rep. Rufus Rodriguez and Rep. Maximo Rodriguez Jr., would impose a unified ₱10-per-milliliter tax on vapor products, with 5% annual increases beginning in 2027. Rodriguez says the proposal could generate an average ₱6 billion in annual collections from 2027 through 2030. The debate comes as the Philippine government considers tobacco, vape and other health-tax reforms to help offset around ₱66 billion in revenue expected to be forgone under a proposed tax-relief package.
