FRIDAY, May 20, 2022 (HealthDay News) — A rising variety of U.S. youngsters are vaping marijuana — a behavior that in some methods could also be extra dangerous than old style pot smoking, a brand new examine finds.

Researchers discovered that between 2017 and 2019, the share of teenagers who reported any marijuana use up to now month ticked upward barely — from 13.9% to fifteen.4%.

What actually modified, the examine discovered, was how children had been utilizing the drug. There was a pointy improve in vaping, whereas conventional marijuana smoking declined.

The share of children who stated they vaped marijuana “steadily” — at the least as soon as per week — greater than doubled, from 2.1% to five.4%. Occasional use (one to 6 occasions a month) rose to an identical diploma.

At the identical time, the proportion of children who smoke marijuana declined. In essence, vaping appeared to be changing smoking, based on lead researcher Katherine Keyes, a professor at Columbia University Mailman School of Public Health in New York City.

She stated she might solely speculate in regards to the causes. But the rising recognition of vaping nicotine, together with legalization and altering social norms round marijuana, are possible components, Keyes stated.

Those factors had been echoed by Linda Richter, vp of prevention analysis and evaluation for the nonprofit Partnership to End Addiction.

She stated previous analysis affords some “compelling explanations” for the traits seen on this examine.

“First, the wave of nicotine vaping that unfold all through center and excessive faculties over the previous a number of years elevated the chance that children who vape nicotine will transition to vaping marijuana,” stated Richter, who was not concerned within the examine.

Vaping, she added, has turn out 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 had been initially launched to the market, they had been marketed as safer options to cigarette smoking,” Richter stated.

But vaping is way from benign. And on the subject of marijuana, Keyes stated, vaping can really ship a better dose of THC than smoking does. THC is the lively ingredient behind marijuana’s “excessive.”

That larger THC dose, Richter stated, can “hook younger folks to the substance and hold them coming again for extra.”

And whereas vaping doesn’t contain smoke, the liquids utilized in vaporizers do include doubtlessly poisonous chemical substances, Richter identified. Vitamin E acetate, an additive in some THC-containing vaping merchandise, has been linked to extreme — and generally deadly — lung accidents.

That lack of smoke can also be an issue of kinds: Kids can conceal marijuana vaping extra simply than smoking, Richter stated, as a result of there isn’t any telltale pot odor.

The new findings — revealed May 19 within the journal Addiction — are based mostly on greater than 51,000 U.S. teenagers who took half in annual well being survey between 2017 and 2019.

During that point, marijuana vaping rose amongst girls and boys, with a big spike in these utilizing at the least as soon as per week: from 2.9% to six.2% amongst boys, and from 1.3% to 4.7% amongst women.

By 2019, marijuana vaping was extra widespread than conventional pot smoking amongst all racial and ethnic teams, aside from Black teenagers.

Keyes additionally pointed to a discovering from a earlier examine of the identical group of teenagers: High faculty seniors reported an particularly sharp rise in marijuana vaping — with the prevalence almost tripling, from 5% to 14%.

The vaping craze presents mother and father with some troublesome points, based on Keyes and Richter. Not solely is marijuana use tougher to note, however children are additionally seeing marijuana vaping merchandise marketed in all places, together with on social media, they identified.

“It’s not a matter of whether or not your little one might be uncovered to this, however when,” Keyes stated. “The smartest thing mother and father can do is to speak to their children about marijuana use, and begin early — in center faculty.”
