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

A new Virginia law that took effect on July 1, 2026, requires retailers to obtain permits to sell liquid nicotine, vape and tobacco products, while directing Virginia ABC to conduct inspections and verify that stores sell only products listed in the state directory.

Smoore’s first-half 2026 revenue rose 19.9%, but the results revealed growing structural risks beneath the headline growth. Heat-not-burn contributed about 61% of incremental revenue and remains driven largely by one core customer, while traditional vaping markets diverged, own-brand growth slowed and China enterprise revenue declined further. Gross profit and adjusted profit lagged revenue growth, while second-quarter revenue growth slowed to about 1.9%, putting greater focus on the quality, concentration and sustainability of Smoore’s expansion.

A new expert paper in JAMA urges U.S. clinicians to include nicotine e-cigarettes in smoking-cessation discussions, citing higher quit rates than nicotine replacement therapy. It also stresses that products must deliver enough nicotine to replace cigarettes, dual use should be brief, and complete switching is the goal. 2Firsts argues the recommendations matter beyond clinics: public-health professionals should reassess relative risk, regulators should preserve sufficient product appeal for adult smokers, and manufacturers should focus on helping users quit cigarettes more sustainably.

Less than a week after JUUL2 received U.S. FDA marketing authorization on August 28, 2026, JUUL Labs was sued for patent infringement in federal court in Delaware. AJ Marketing LLC filed the complaint on September 3, alleging that both JUUL 1 and JUUL2 infringe U.S. Patent No. 8,851,068 B2. The patent covers aspects of programmable electronic vaporization devices, including controls over dose delivery, usage frequency and operating parameters. The plaintiff is seeking reasonable royalties and ongoing royalties tied to the remaining life of the patent. JUUL has not yet publicly responded to the case.

China-based China Tobacco Hubei Industrial Co., Ltd. has filed a patent application covering an oral nicotine product and its preparation method. The patent proposes a soft candy-shaped oral nicotine product containing nicotine ingredients, gelling agents, sweeteners and alkaline pH regulators. Through formulation adjustments and homogeneous or dual-layer structures, the technology aims to achieve different nicotine release profiles. The filing reflects exploration of new oral nicotine product formats and controlled nicotine delivery approaches.

China’s vape exports to the U.S. reached approximately $1.58 billion in the first half of 2026, remaining broadly stable from a year earlier but still below previous growth momentum. 2Firsts’ analysis of China Customs data shows that the U.S. market has not simply returned to its previous trajectory after the enforcement shock and inventory-driven swings of 2025. Instead, export momentum is shifting across product categories. Vaping devices and atomization hardware increased 15.2% year over year, while 6-methyl nicotine-related and other nicotine substitute products surged 234.7%. Meanwhile, traditional nicotine-containing vaping products continued to face pressure.
