Why E-Cigarettes Might Not Be As Safe As You Think
It’s little wonder why e-cigarettes’ popularity has exploded into a multi-billion industry around the world over the last few years; the promise of safe, harmless nicotine delivery without all the carcinogenic byproducts of looseleaf combustion is a hard offer to pass up. But are these devices and the nicotinated fluids they atomize really that safe? Science says it’s complicated.
E-cigarettes are quite the media darling these days — despite the banishment of conventional smokers in television spots since the 1970s — appearing in everything from Super Bowl ads to the hands of late-night talk show guests. The CDC found that e-cig usage jumped from around 10 per cent in 2010 to more than 21 per cent in 2011 among adults who already smoked conventional cigarettes. Similarly, 10 per cent of American high school seniors reported experimenting with e-cigarettes over the same period.
What exactly is an e-cigarette? US patent application No. 8,490,628 B2 defines an e-cigarette as “an electronic atomization cigarette that functions as substitutes [sic] for quitting smoking and cigarette substitutes.” They were first invented in 2002 by a Chinese pharmacist as smoking cessation devices, and China remains the primary manufacturer of e-cigarettes globally today. The devices atomize a nicotinated propylene glycol solution, known as e-liquid, that may be doctored with additional additives, such as flavorings and colorings or variable nicotine concentrations. They can also be modified to vaporize cannabis derived products.
