"A tripwire question asks about use of salvia (or salvia divinorum) in the last 12 months. Salvia is an herb with hallucinogenic properties, common to southern Mexico and Central and South Americas. Although it currently is not a drug regulated by the Controlled Substances Act, several states have passed legislation to regulate its use, as have several countries. The Drug Enforcement Agency lists salvia as a drug of concern and has considered classifying it as a Schedule I drug, like LSD or marijuana. Annual prevalence of this drug has been in a steady decline, and in 2019 levels were less than 1% in all grades at 0.8%, 0.9%, and 0.7% among 8th, 10th, and 12th graders, respectively."
