Self-reported use of marijuana in electronic cigarettes has risen among US teenagers, two studies have found.
The research letters, published in JAMA,12 looked at marijuana vaping rates from 2017 to 2019 among young people in middle and high school (aged 11 to 18) and noted increases at all ages. The authors said that this could relate to an increase in sales of e-cigarette products, easier access to marijuana through informal sources, and a reduced perception of harm related to marijuana use.
They warned, “Marijuana vaping produces significantly greater physiological and psychological effects compared with traditional smoking methods at the same tetrahydrocannabinol levels, raising concerns about potential health effects.”
