Over 1 In 10 High School Seniors Report Using Delta-8 THC

More than 11% of high school seniors report using delta-8 THC — a compound closely related to the psychoactive chemical in marijuana that’s legal in many states thanks to a loophole in the 2018 farm bill — according to a study published Tuesday in the Journal of the American Medical Association. The study, led by researchers at the Keck School of Medicine at the University of Southern California, is one of the first to offer a nationwide snapshot of teenage use of delta-8, a little-researched cannabis product with psychoactive effects that has grown in popularity in recent years.
