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

Among a nationally representative sample of 125,550 US adolescents surveyed between 2001 and 2019, 8.4% reported using hallucinogens. The prevalence of hallucinogen use decreased from 13.3% in 2001 to 7.0% in 2019. Adolescents who used hallucinogens had higher odds of feeling sad and hopeless, considering suicide, and planning suicide. They also showed a higher prevalence of using other substances, including alcohol, cigarettes, marijuana, and cocaine. The findings indicate an association between adolescent hallucinogen use and increased hopelessness, suicidality, and co-occurring substance use.

Abstract

(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’s 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 < 0.0001). Hallucinogen users were at high odds of feeling sad and hopeless (aOR: 1.40; 95%CI: 1.21–1.61; p < 0.0001), considering suicide (aOR: 1.36; 95%CI: 1.08–1.70; p = 0.009), and planning suicide (aOR: 1.49; 95%CI: 1.19–1.86; p = 0.001). Additionally, adolescent hallucinogen users had a higher prevalence of alcohol, cigarette, e-cigarette, marijuana, synthetic marijuana, inhalants, heroin, cocaine, methamphetamine, and ecstasy use. (4) Conclusions: The overall trend of hallucinogen use decreased among school-going American adolescents. We found a high prevalence of co-occurring substance use among hallucinogen users. We found that hallucinogen users were at high odds of feeling sad, hopeless, and considering and planning suicide. Further research is needed to explore the effects of recreational hallucinogen use among the adolescent population.
