The Supreme Court will hear a vaping case on Monday, weighing federal regulators' decisions blocking sweet vaping products after e-cigarette use spiked among kids.

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 U.S. Supreme Court will hear arguments Monday on whether to reinstate a federal ban on sweet-flavored vaping products. The case centers on the FDA 's efforts to regulate e-cigarettes to fight teen nicotine addiction. Experts say past bans helped drive down "epidemic" levels of young people vaping in 2019.

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.
