Among 10th-graders, 19.4 percent had vaped the drug in the previous year, and among eighth-graders, 7 percent said they had. “This is a really big increase,” Jonathan P. Caulkins, a drug-policy researcher at Carnegie Mellon University, wrote in an email. Caulkins said he had expected large increases in states that have legalized marijuana, but not a nationwide rise of such proportions.

In the survey, 35 percent of 12th-graders reported vaping nicotine in the previous 12 months, up 5.6 percentage points from 2018.
