The US Food and Drug Administration is clamping down on illegal online sales of e-cigarettes, sending 24 letters to websites for selling to people under 18 years old, according to a report in the Wall Street Journal.
Last month, the agency assumed responsibility for overseeing e-cigarettes. It released the letters Thursday, giving the sites 15 days to respond with plans to prevent future sales to minors. Repeat offenders face a $275 fine.
The FDA also warned 28 offline retailers of cigars and e-cigs and three letters to websites selling cigars.
