Therapeutic Potential of Psychedelic Drugs: Navigating High Hopes, Strong Claims, Weak Evidence, and Big Money
Annual Review of Psychology – August 02, 2024

Summary
Psychedelics show therapeutic potential in emerging drug studies. Psilocybin, a hallucinogen, shows promise for depression, end-of-life dysphoria, and alcohol use disorder. MDMA (Ecstasy) is being explored for PTSD. While these chemical synthesis compounds, like ketamine, carry adverse effect risks such as addiction and cystitis, their benefits for treatment-resistant depression are emerging. Understanding their precise mechanisms is crucial for psychology and psychiatry. Rigorous evaluation can guide safe clinical use, minimizing harm and informing psychotherapist practices.
Abstract
Therapeutic claims about many psychedelic drugs have not been evaluated in any studies of even modest rigor. The science of psychedelic drugs is strengthening, however, making it easier to differentiate some promising findings amid the hype that suffuses this research area. Ketamine has risks of adverse side effects (e.g., addiction and cystitis), but multiple studies suggest it can benefit individuals with treatment-resistant depression. Other therapeutic signals from psychedelic drug research that merit rigorous replication studies include 3,4-Methylenedioxymethamphetamine (MDMA) for post-traumatic stress disorder (PTSD) and psilocybin for depression, end of life dysphoria, and alcohol use disorder. The precise mechanisms through which psychedelic drugs can produce benefit and harm are not fully understood. Rigorous research is the best path forward for evaluating the therapeutic potential and mechanisms of psychedelic drugs. Policies governing the clinical use of these drugs should be informed by evidence and prioritize the protection of public health over the profit motive.
