All 17 companies that received an FDA warning letter in May have ceased marketing e-cigarette liquids with packaging resembling child-friendly food products, such as candies, cookies and juice boxes, the FDA said. “Even as we encourage the innovation of novel and potentially less harmful products such as e-cigarettes for currently addicted adult smokers, we’re committed to holding industry accountable to ensure these products aren’t being marketed to, sold to, or used by kids,” said FDA Commissioner Scott Gottlieb.
