Vaping, she added, has grow to be “normalized,” whereas on the identical time “pro-marijuana messages” have grown.
“Vaped merchandise are additionally sometimes seen as safer and more healthy than smoked merchandise, as a result of when e-cigarettes have been initially launched to the market, they have been marketed as safer options to cigarette smoking,” Richter mentioned.
However vaping is much from benign. And in relation to marijuana, Keyes mentioned, vaping can truly ship a better dose of THC than smoking does. THC is the lively ingredient behind marijuana’s “excessive.”
That greater THC dose, Richter mentioned, can “hook younger individuals to the substance and maintain them coming again for extra.”
And whereas vaping doesn’t contain smoke, the liquids utilized in vaporizers do include probably poisonous chemical substances, Richter identified. Vitamin E acetate, an additive in some THC-containing vaping merchandise, has been linked to extreme — and typically deadly — lung accidents.
That lack of smoke can also be an issue of kinds: Youngsters can conceal marijuana vaping extra simply than smoking, Richter mentioned, as a result of there is not any telltale pot odor.

Keyes additionally pointed to a discovering from a earlier research of the identical group of teenagers: Highschool seniors reported an particularly sharp rise in marijuana vaping — with the prevalence practically tripling, from 5% to 14%.
The vaping craze presents dad and mom with some tough points, in keeping with Keyes and Richter. Not solely is marijuana use more durable to note, however youngsters are additionally seeing marijuana vaping merchandise marketed in all places, together with on social media, they identified.
“It is not a matter of whether or not your youngster shall be uncovered to this, however when,” Keyes mentioned. “The very best factor dad and mom can do is to speak to their youngsters about marijuana use, and begin early — in center college.”
