Cooling ingredients in vapes might cause irregular heartbeats

Article excerpt

Menthol and other cooling agents in e-cigarettes may trigger irregular heartbeats, according to emerging research that shifts focus away from nicotine as the primary health concern. For years, flavor additives were largely dismissed as minor players in vaping's health impacts, overshadowed by worries about addiction and lung damage. But scientists are now investigating whether these flavoring compounds, particularly cooling ingredients, pose cardiovascular risks independent of nicotine exposure. The finding suggests regulators may need to expand their scrutiny beyond nicotine delivery to address previously overlooked chemical constituents in vape products.
