A new survey has found vaping rates among teens and young adults have dropped significantly during the pandemic.

Researchers at Stanford University found 32% of teens and young adults who used e-cigarettes said they quit this year, while another 35% said they had cut back on vaping, HealthDay reports.

One-fourth of survey respondents who cut back or quit said concerns about lung health were a major factor in their decision, the researchers reported in JAMA Network Open.

The researchers conducted a nationwide online survey in early May, with more than 4,300 participants ages 13 to 24. Almost 2,200 of the participants said they had used e-cigarettes.

Those who adhered to stay-at-home mandates were 50% more likely to quit or reduce their e-cigarette use. Only about 15% of those who cut down or quit said they did so because they were concerned their parents would find out they vape, the survey found.
