"Hallucinogens is another fairly widely used class of illicit substances. Lifetime prevalence of use is 2.4% for 8th graders, 4.7% for 10th graders, and 6.9% for 12th graders. Until 2001, hallucinogen prevalence ranked this high primarily due to the prevalence of LSD use. But in 2019, similar proportions of students indicated lifetime use of hallucinogens other than LSD – 1.7%, 3.3%, and 4.3% for 8th, 10th, and 12th grade, respectively – (particularly “shrooms” or psylocibin), compared to 1.6%, 3.6%, and 5.6% for LSD."
