Science, healthcare providers and patients are increasingly finding that psychedelics can be uniquely effective treatments for a wide range of mental health conditions. What is less well-known, but also well-established, is that psychedelics can also be powerful treatments for chronic pain.

Classic psychedelics include psilocybin/psilocin (magic mushrooms), LSD, mescaline and dimethyltryptamine (DMT), a compound found in plants and animals that can be used as a mind-altering drug. Atypical psychedelics include MDMA (molly or ecstasy) and the anesthetic ketamine.

More than 60 scientific studies have shown the ability of psychedelics to reduce the sensation of acute pain and to lower or resolve chronic pain conditions such as fibromyalgia, cluster headache and complex regional pain syndrome (CRPS).

The complexity of pain is well matched by the multiple ways that psychedelic substances impact human physiology and perception. Psychedelics have a number of biological effects that can reduce or prevent pain through anti-nociceptive and anti-inflammatory effects. Psychedelics can also create neuroplasticity that alters and improves reflexive responses and perceptions of pain, and helps make pain seem less important. 

New mechanisms of action for how psychedelics improve pain are continually being discovered and proposed. Mounting evidence seems to show that a confluence of biological, psychological and social factors contribute to the potential of psychedelics to treat complex chronic pain. 

It is premature to state that there is one key or overarching mechanism at work. Research continues to explore different ways that psychedelics, combined with or without adjunctive therapies, can impact a wide range of pain conditions.

The National Institutes of Health recently posted a major funding opportunity to study psychedelics for chronic pain in older adults. And for the first time, PAINWeek, one of the largest conferences focused on pain management, has an entire track dedicated to Psychedelics for Pain at its annual meeting next month in Las Vegas. 

Clearly, pain management leaders are welcoming psychedelics as a vitally needed, novel treatment modality, and it is time for healthcare providers and patients to begin learning about this burgeoning field.

It is important to note that all classic psychedelics are currently illegal Schedule I controlled substances in the US. The FDA has granted Breakthrough Therapy Designation to multiple psychedelics, potentially accelerating access, but the road to approval at the federal level is long. 

However, at the state level, the landscape is changing rapidly. Similar to how states led the way in expanding legal access to cannabis, we are now seeing the same pattern with psychedelics. 

In 2020, Oregon voters approved an initiative that makes facilitated psilocybin sessions available to adults who can afford the treatment. 

Voters in Colorado approved a similar measure in 2022, with services becoming available in 2025. To become a certified facilitator in Colorado, individuals must pass a rigorous training program that includes required instruction on the use of natural psychedelics to treat chronic pain. 

This coming November, voters in Massachusetts will also decide on creating legal access to psychedelics. 

Over the next decade, we will likely see multiple pathways to access, such as continued expansion of state-licensed psychedelic therapies; FDA-approved psychedelic medicines; and the latest proposed model of responsible access, Personal Psychedelic Permits. The last option would allow for the independent use of select psychedelics after completing a medical screening and education course focused on benefits and harm reduction. Overall, we need policies that lead to safe supply, safe use and safe support.

As psychedelics have become more socially accepted and available, rates of use are increasing. This includes everything from large “heroic” doses, where people experience major shifts in perception and profound insights, to “microdoses” that are sub-perceptual and easily integrated into everyday life. 

In the area of chronic pain, a lot of the focus is on finding low-doses that are strong enough to reduce pain, but have no or minor visual effects. This amount seems sufficient for many people to activate the necessary receptors to reduce chronic pain.

While doctors are years away from being able to prescribe psychedelics, increasing public usage indicates that now is the time for the medical community to become more knowledgeable about psychedelic-pharmaceutical interactions and psychedelic best practices to serve the safety and healing of their patients.

We also need healthcare providers and pain patients to join the advocacy fight for increased research and expanded access to psychedelics. Providers have the medical training and knowledge to treat pain, while patients often have compelling personal stories of suffering and their own form of expertise based on lived experience. 

One of the most effective lobbying tandems is a patient who can share a powerful personal story of healing, hope and medical need, combined with the expertise and authority of a doctor. Together, we can create a world with responsible, legal access to psychedelic substances that lead to significant reductions in pain and suffering.

Kevin Lenaburg is the Executive Director of the Psychedelics & Pain Association (PPA) and the Policy Director for Clusterbusters, a nonprofit organization that serves people with cluster headache, one of the most painful conditions known to medicine. 

On September 28th and 29th, PPA is hosting its annual online Psychedelics & Pain Symposium, which features presentations from experts and patients in the field of psychedelics for chronic pain and other medical conditions. The first day is free and the second day is offered on a sliding scale, starting at $25.
