The fall day is cloudless, calm and temperate. I’ve just finished a great meal on the patio of a popular cafĂ© not far from the Plaza. An espresso is en route, and now, there’s only one thing left to do to complete the perfection of my dining experience: scratch a decades-old nicotine itch.
I take a familiar puff, a deep inhale, and there’s a warm collision at the back of my throat. I exhale: a dense but quickly dissipating cloud. It gets better as I repeat the ritual and pair it with the just-delivered caffeine concentrate.
But suddenly I’m aware that this whole thing might not be as satisfying for my waiter and the restaurant’s other patrons as it is for me. No one says a word. The looks I’m catching, though, as I billow out another nebula, range from disgust to curiosity.
That’s not smoke coming out of my mouth; it’s water-vapor. Nothing’s on fire. There’s been no combustion. Still, confusion reigns. So I find a quiet patch of shaded grass beyond the confines of the patio to enjoy what’s left of the afternoon–and my electronic cigarette.
The diners and staff at the restaurant are far from alone in their befuddlement, curiosity and inherent distrust about “e-cigarettes.” They have been around a decade but are only recently becoming ubiquitous in urban society. Studies and surveys show that millions of people are using e-cigarettes, and the number is steadily climbing. Financial analysts predict that, by year’s end, e-cigarettes will comprise an industry that has doubled in size since 2012 to become worth more than a billion dollars. Some even say the rise of the e-cig has contributed to a slight decline in cigarette sales.
The market’s explosive growth, its lack of regulation, an increase in use among children, pressing medical questions about health effects and the products’ association with one of America’s true social pariahs has placed e-cigarettes at the center of a vigorous national public health debate. That debate has found footholds at the state and local levels, too.
Essentially, e-cigarettes are battery-powered devices that heat a solution of vegetable glycerin, propylene glycol and artificial flavoring, converting the mixture into vapor the user inhales. The act has birthed a new verb into the parlance: vaping. The overwhelming majority of vapers, me included, buy e-cig juice that’s infused with the highly addictive drug nicotine at a level chosen by the purchaser.
