A review in Nature Reviews Cardiology maps a hierarchy of vascular harm across every nicotine product. Nicotine pouches sit at the bottom — least harmful among nicotine products — but impair endothelial function, raise oxidative stress and arterial stiffness, and have no long-term outcome data.

Three University of Gothenburg studies found adolescents who use nicotine — including tobacco-free nicotine pouches — report more anxiety and depression symptoms, with girls particularly vulnerable. A companion rat study showed nicotine altered the amygdala, most pronounced in females.

The Alabama Department of Corrections is banning tobacco across all state prisons starting September 1 — but ZYN nicotine pouches and NicoDerm patches stay in canteens. The policy affects 21,000+ inmates and separates tobacco from nicotine in a way no other state prison system has.

A BAT-funded study in BMC Chemistry measured 132 chemicals across 11 nicotine pouches, two snus products and cigarette-smoke data. Pouches came out with fewer detectable toxicants and over 90% lower levels than snus in most tests — but nine of the pouches tested were Velo, made by the funder.

A peer-reviewed review in Frontiers in Oral Health finds nicotine pouches remove the combustion that drives smoking-related oral cancer, but no long-term data exists to say what they mean for cancer risk. A separate UK dental-team update flags mucosal lesions and gum recession among users.
