With e-cigarette sales booming, the Supreme Court will decide whether the FDA unlawfully blocked approval of more than a million new flavored nicotine products.

The U.S. Supreme Court is set on Monday to hear the U.S. Food and Drug Administration's defense of the agency's refusal to let two e-cigarette companies sell flavored vape products that regulators found to pose a significant health risk to youths.

The Supreme Court is scheduled Monday to consider the regulation of flavored e-cigarettes in a case that illustrates an enduring public health conundrum: how to keep kids away from sweet-flavored, addictive vapes while giving adult smokers better options to help them quit cigarettes.

WASHINGTON −Six years after teen vaping was declared an epidemic, the use of e-cigarettes by young people has declined to its lowest level in a decade. “That’s a big deal,” Health and Human Services Secretary Xavier Becerra said in September when announcing usage had dropped to 6% among middle and high school students.

The Supreme Court on Monday will hear a dispute over the Food and Drug Administration's refusal to approve flavored e-cigarettes over public health concerns.
