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 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.

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.
