With the advent of e-cigarettes, millions of smokers gained a way to get their nicotine fix without many of the negative health effects of lighting tobacco on fire. Of course, because the technology is relatively new, there’s plenty we don’t know about any other adverse long-term effects. That’s one reason it’s particularly troubling that young people have adopted vaping, too.
Now the latest data on youth vaping trends is out, and it’s showing some interesting gender differences. In a letter published today in JAMA Pediatrics, a team of researchers from the Medical University of South Carolina reports that vaping is on the rise among girls. For decades, the reverse was true—more men and boys indulged in nicotine products than women.
But according to data from the youth cohort for the Population Assessment of Tobacco and Health (PATH) study, girls have been more likely to vape than boys since 2021, with a wider gap in older teens.

The data came from self-reported surveys, which means it’s likely the findings underestimate the magnitude of the problem.
We’re talking about adolescents who are regularly using e-cigarettes now.” Older teen girls (aged 15-17) saw the biggest rise in vaping with 4.9 percent of them reporting regular use in 2021 and 7.8 percent in 2024. By contrast, only 4.6 percent of boys in the same age cohort said they were regular users in 2024. According to the team, the latest data show a drop in teen girls vaping, but the gender gap still persists and the reasons remain unclear.
Vaping was more common among boys from 2014 through 2018, then a spike in both genders in 2018 and 2019 erased the gender gap. According to the team, this surge coincides with the popularity of new products like JUUL e-cigarettes—slim, rechargeable devices that use disposable cartridges of nicotine-salts in glycerol and propylene glycol. The good news is that the number of teens smoking combustible cigarettes has dropped precipitously.
According to the data, less than half of 1 percent of both boys and girls were established smokers, something the team calls a “massive health win.” Still, nicotine by itself carries its own negative health externalities. For adolescents, that includes addiction at a time when their brains are still developing. Vaping may be safer than smoking, but without long-term data we won’t know exactly what teens are risking by picking up the habit.
