You could be eligible to participate in a psychedelic research trial. Studies of psychedelics are at various stages, enrolling both healthy volunteers and individuals with specific mental health conditions. We’ve compiled a list here of all the current or planned clinical trials on MDMA, psilocybin, LSD, Cannabis, and more. Regulatory approvals over the last few decades gave way to MDMA and psilocybin pilot studies and clinical trials, while research around the world is exponentially growing. New investigations for the therapeutic use of psychedelics, as well as inquiries into how the brain works and what constitutes consciousness are appearing all the time.

It seems we’ve reached a new frontier where many academic scientists and investigators in private psychiatric practices are able to pursue research on psychedelics without facing opposition based on stigma or antiquated information about safety concerns. While this may still not yet be the case for many Universities, the forerunners in this field will pave the way for others by contributing evidence-based findings to the body of knowledge. Since we have better technologically advanced tools and more rigorous study designs than ever before, all research in current day is extremely valuable.

Background: How does a clinical trial work?

Clinical trials collect data to evaluate safety and effectiveness of drugs under investigation in research. Drugs must pass through a sequence of phases or stages to become approved and available to patients. A new substance is first thoroughly tested in human cells and/or animals to gain initial information about safety and toxicity. After review, FDA can grant approval to test the drug in a small number of healthy individuals (phase 1). The next phase of testing involves giving a drug to people who have a disease or condition (phase 2) to evaluate safety and effectiveness to reduce symptoms. If the drug appears safe and signals the potential to be a useful treatment, then a much larger number of people are tested in phase 3 trials at multiple study sites. For the FDA to approve a new drug for a specific condition or disease, two phase 3 trials must show significant benefit that outweighs the risks or negative side effects of taking the drug. After the drug is approved and sold in the consumer market, research continues in phase 4 known as post marketing surveillance trials. Phase 4 trials collect data on long-term effectiveness and safety, costs associated with treatment compared to other drugs in the market, and safety and effectiveness of the new drug versus other available treatment options.

Following is a list of current or planned clinical trials with psychedelics (as of July 2018) in healthy individuals and in people with a specific medical condition. We searched clinical trial registries for USA, EU, and Brazil. While we’ve attempted to make this list comprehensive, new trials are emerging often and our online search may not have revealed all. We plan to keep this list updated. If you know of clinical trials not listed here, please email us at info@psychedelic.support
