2021 US vaping rates among 18-24-year-olds rose to 11% from 7.6% in 2018, with high nicotine levels and "stealth culture"

Vaping rates among young adults (18-24) in the US have risen from 7.6% in 2018 to 11% in 2021, while high school vaping rates have dropped. Research shows nicotine's high reward value for young brains, combined with high nicotine levels in devices and "stealth culture," makes quitting difficult. Many who began vaping during its peak continue the habit, raising concerns about a generation-wide addiction.
