Are E-Cigarettes Safe? Here ’s What the Science Says
In 1965, when Herbert Gilbert was granted the first patent on a smoke- and tobacco-free cigarette, he wrote that the product would “provide a safe and harmless means for and method of smoking.”
More than 60 years later, however, modern iterations of Gilbert’s invention have sparked debate in the public-health community. E-cigarettes, which have grown increasingly popular in the past five years, were designed as a tool to help people quit smoking—and by doing so they should drastically reduce rates of lung cancer and other diseases. But the question is, does that potential outweigh their possible risks to human health?
No easy answer
Traditional cigarettes work by simple combustion: when tobacco is lit, it combines with oxygen and creates an inhalable smoke. E-cigarettes, sold by brands including Juul, Blu and Vuse, heat a chemical-packed liquid that typically contains nicotine and often a flavoring agent, creating an aerosol. By delivering nicotine without tar and other nasty by-products of combustion, e-cigarettes purportedly give smokers a healthier alternative to cigarettes while still satisfying cravings.
It seems like a win-win. But in practice, there is no consensus yet about whether or not e-cigarettes effectively help smokers ditch cigarettes. Vapes, as they’re called, contain fewer of the cancer-causing chemicals found in traditional cigarettes (like arsenic, benzene and formaldehyde), but there is little l...
