Island breeze, blue lagoon, dew drop-;these aren’t the names of scented candles on display at your local home goods store. They’re flavors of synthetic nicotine used in e-cigarettes, often advertised with neon-electric colors and bright lettering to make them look like boxes of candy or fruit juice. But underneath all the flair, a specific label written clearly in black text on a white background is required by law to be there: a warning that says the product contains nicotine and that nicotine is an addictive substance.
