Carolyn Smeaton is worried. The 48-year-old resident of Fall River, MA, used to smoke 3 packs a day, but cut that amount in half by supplementing her habit with e-cigarettes-liquid nicotine vaporizers. "It's far exceeded my expectations," she told her local paper last month. "I feel like this could save my life," she tells the New York Times. Now, however, the FDA is threatening to ban the products. "I'm a nervous wreck," Smeaton informs the Wall Street Journal. With all those reporters calling her for quotes on the product, no wonder! The woman deserves a smoke.
