Hopelessness, Suicidality, and Co-Occurring Substance Use among Adolescent Hallucinogen Users-A National Survey Study.

(1) Objectives: Hallucinogens are being explored as a potential treatment of psychiatric disorders. Micro dosing of illicitly purchased hallucinogen drugs is on the rise despite conclusive benefits. We aimed to evaluate the prevalence and odds of hopelessness, suicidality, and co-occurring substance use among adolescent hallucinogen users. (2) Methods: We performed a retrospective analysis of the Centers for Disease Control and Prevention\u27s Youth Risk Behavior Surveillance System (YRBSS) 2001-2019 data that nationally represents school-going US adolescents. We identified hallucinogen use based on the survey questions, exploring the use of hallucinogens (LSD, PCP, mescaline, and mushrooms). (3) Results: Out of a total of 125,550 respondents, 8.4% reported using hallucinogens. Overall, the trend of hallucinogen use decreased from 13.3% (2001) to 7.0% (2019) (pTrend \u3c 0.0001). Hallucinogen users were at high odds of feeling sad and hopeless (aOR: 1.40; 95%CI: 1.21-1.61
