Two million US teens are vaping marijuana

Of the slightly more than 20,000 teens surveyed in the school-based study, 9% self-reported that they had vaped marijuana.

Almost one in three young e-cigarette users said they had tried cannabis with e-cigarettes at least once, survey results showed. That extrapolates to 2.1 million middle and high school students using e-cigarettes to get high on cannabis products.

Vaping is generally considered less unsafe than smoking, because burning tobacco or marijuana generates chemicals that are harmful to lungs.

Roughly one in 11 American middle and high school students have used cannabis in e-cigarettes, a study suggests.

The researchers acknowledge in JAMA Pediatrics that the study wasn't a controlled experiment created to prove whether or how vaping on its own or using cannabis in e-cigarettes might directly cause health problems.

The number is worrying "because cannabis use among youth can adversely affect learning and memory and may impair later academic achievement and education", said lead researcher Katrina Trivers of the Centers for Disease Control and Prevention.

There's also a risk that vaping cannabis may expose teens to more potent doses of the drug and higher levels of chemicals in marijuana like THC (tetrahydrocannabinol) than they might get by smoking a joint, said Wayne Hall of the Centre for Youth Substance Abuse Research at the University of Queensland in Australia. Juul, by far the most popular e-cigarette device, does not offer marijuana pods, but users can re-fill cartridges with cannabis oil. It was the first time a question about marijuana vaping was asked on this particular survey.

A different survey from the University of MI in December found similar results when it asked for the first time about marijuana vaping.

"The health risks of vaping reside not only in the vaping devices, but in the social environment that comes with it", said University of MI researcher Richard Miech.
