Ask thousands of teens whether frequent use of certain substances brings a high risk of harm, and they mostly nail it: a majority say yes for cigarettes, alcohol, cocaine and heroin. But there’s one substance that many skip over — cannabis.
It’s a sentiment that some of their parents may share. Parents often don’t understand that the products used today “are not what they knew when they were in high school,” says Kelly Young-Wolff, a licensed clinical psychologist and research scientist at Kaiser Permanente Northern California Division of Research in Oakland. If their children are using cannabis, parents may think, “‘it’s not that bad, at least they’re not using this other drug that’s worse.’”
But the cannabis products available now are leaps and bounds more potent — which may increase the risks for addiction and psychosis — than in the past. Marijuana plants have been bred to contain more delta-9-tetrahydrocannabinol, or THC, the main psychoactive chemical. In 1995, the total percent of THC by weight of marijuana plant material was around 4 percent; now marijuana with a THC potency of 20 percent or more is available. Trouncing that are concentrated cannabis products, including wax, budder and shatter, which can have a THC potency as high as 95 percent.
Cannabis is legal for adults to use recreationally in 24 states and Washington, D.C., and is allowed for medical use in 38 states and D.C. The widespread availability of cannabis “promotes the idea that it’s safe,” says pediatrician Beth Ebel of the University of Washington School of Medicine and Seattle Children’s Hospital. But that “is an incorrect assumption.” THC can impact brain chemistry “in a way that wasn’t intended,” Ebel says. “Some of the worst effects can have lifelong health consequences, especially for a young person.”
