Can Psychedelics Be a New Option for Pain Management?

By Kevin Lenaburg

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.

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.

Ketamine Gets FDA Orphan Drug Designation for CRPS

By Pat Anson, PNN Editor

A Canadian biotech company has announced it has been granted orphan drug designation from the U.S. Food and Drug Administration to investigate the use of ketamine as a treatment for Complex Regional Pain Syndrome (CRPS)¸ a disorder of the nervous system that causes severe, intractable nerve pain. Currently, there is no FDA approved medication for CRPS.

Toronto-based PharmaTher Holdings specializes in the development of ketamine and other psychedelic drugs for mental health and pain conditions. The company also recently received an orphan drug designation for ketamine as a treatment for Amyotrophic Lateral Sclerosis (ALS), more commonly known as Lou Gehrig's disease.

“Receiving our second FDA orphan drug designation with ketamine for CRPS continues our momentum in building a specialty ketamine-based product pipeline for not only mental health disorders, but also for rare and near-rare conditions present in neurological, pain and inflammatory disorders,” Fabio Chianelli, CEO of PharmaTher, said in a statement.

Ketamine is not an opioid, but acts on pain receptors in the brain in a similar manner. Although the drug is only approved by the FDA for anesthesia and depression, a growing number of clinics provide off-label infusions of ketamine to treat difficult chronic pain conditions such as CRPS. In high-dose infusions, ketamine puts patients into a temporary dream-like state that can lead to hallucinations and out-of-body experiences.

The FDA first approved ketamine in 1970 and the medical patent on it expired years ago. The goal of PharmaTher is to develop its own propriety formulation of ketamine and expand its use. Orphan drug designation helps speed that process along by encouraging companies to invest in new uses for old drugs, often jacking up the price in the process.

If successful, PharmaTher says it would have seven years of exclusive marketing rights for its ketamine formulation, as well as potential tax credits and the waiver of $2.4 million in FDA filing fees.

In 2019, the FDA approved Spravato, a ketamine-based nasal spray developed by Janssen Pharmaceuticals, as a treatment for depression. A single dose of Spravato costs about $900.

“It seems they are doing something similar to what Janssen did with Spravato,” says Kimberley Juroviesky, a retired nurse practitioner who receives ketamine infusions for CRPS. Juroviesky co-chairs an advocacy group that’s trying to get more insurance coverage of ketamine.

“They are taking ketamine and changing it slightly to create a new drug. Then they can charge hundreds for it. We are hopeful though that maybe this can help us in our fight to get generic ketamine covered by insurance,” she told PNN in an email.

PharmaTher plans to launch a Phase 2 clinical trial of its ketamine formulation in 2022. In addition to treating CRPS, the company recently began a clinical study of ketamine as a treatment for Parkinson’s disease, and has filed a patent application for ketamine as a treatment for obesity and Type 2 diabetes. PharmaTher is also developing a microneedle patch for the delivery of ketamine and other psychedelic drugs.

While ketamine is emerging as a trendy pain reliever and many patients swear by it, medical societies urge caution. Guidelines from the American Society of Anesthesiologists, American Society of Regional Anesthesia and Pain Medicine, and the American Academy of Pain Medicine only support ketamine infusions for CRPS and post-surgical acute pain. The guidelines say there is no evidence supporting ketamine infusions for any other type of pain.

A 2019 study of nearly 300 patients who received ketamine infusions found that over a third reported significant side effects such as hallucinations and visual disturbances.

Can Psychedelics Be Used to Treat Fibromyalgia?

By Pat Anson, PNN Editor

A startup pharmaceutical company has announced plans for a clinical trial to see if a psychedelic compound may be useful in treating fibromyalgia.

California-based Tryp Therapeutics is partnering with scientists at the Chronic Pain & Fatigue Research Center at University of Michigan Medical School for the Phase 2a study, which would be the first to evaluate the effictiveness of psilocybin – the psychoactive compound in “magic mushrooms” -- in treating fibromyalgia.

"We are thrilled to collaborate with such forward-looking clinicians and scientists to develop additional treatment options for fibromyalgia," Jim Gilligan, PhD, Tryp’s President and Chief Science Officer said in a statement.

"The Chronic Pain & Fatigue Research Center at the University of Michigan brings incomparable experience with evaluating treatments for fibromyalgia and other chronic pain indications, and there is nothing more important to our collective team than creating therapies that will address the daily distress of these patients."

The study will evaluate the safety and efficacy of TRYP-8802, an oral formulation of synthetic psilocybin developed by Tryp. The treatment, which will also include psychotherapy, is designed to target pain through neuroplasticity, which alters and reorganizes neural networks in the brain.

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep, anxiety and depression. Standard treatments for fibromyalgia, such as non-steroidal anti-inflammatory drugs (NSAIDs) and gabapentinoids (Lyrica, Neurontin), often prove to be ineffective or have unwelcome side effects.

"Existing treatment options for fibromyalgia are often ineffective and show significant side effects," said Daniel Clauw, MD, Director of the Chronic Pain & Fatigue Research Center.

Tryp plans to submit an Investigational New Drug application to the FDA for the Phase 2 trial in September. Phase 2 studies typically involve a few hundred people with a disease or condition, and are designed to test the safety and efficacy of a treatment.  A much larger Phase 3 study is usually required before the FDA will even consider approval.

Interest in using psychedelics to treat medical conditions has been growing in recent years, primarily as a way to treat depression, anxiety and other mental health issues. Preliminary research suggests that microdoses of LSD, psilocybin and other psychedelics may also be effective in treating pain.

Another pharmaceutical startup – Mind Medicine (MindMed) – recently announced plans to  investigate LSD as a treatment for cluster headache and an unnamed “common, often debilitating, chronic pain syndrome.”

Tryp Therapeutics is focused on developing psilocybin-based compounds for the treatment of diseases with unmet medical needs. The company recently announced a partnership with the University of Michigan to study synthetic psilocybin as a treatment for neuropsychiatric disorders. Tryp is also working with the University of Florida to investigate psilocybin as a treatment for eating disorders.

LSD, psilocybin and other psychedelics are classified as Schedule I controlled substances, meaning they have a high potential for abuse and currently have no accepted medical use in the United States.

MindMed Investigating Use of Psychedelics to Treat Chronic Pain

By Pat Anson, PNN Editor

A startup pharmaceutical company has announced plans to investigate the use of LSD and other psychedelics to treat chronic pain.

New York-based Mind Medicine (MindMed) is exploring the use of psychedelics to treat two pain conditions, which it is calling “Project Angie.” The company is already investigating the use of psychedelics to treat addiction, anxiety and attention deficit hyperactivity disorder (ADHD).

"With the launch of Project Angie, we seek to align closely with MindMed's core mission to improve mental health and combat substance use for the many patients in need. If we can help to develop a new paradigm to treat pain, it may have the potential to greatly reduce the use of addictive medicines such as opioids currently ravaging society and its mental health," MindMed CEO & Co-Founder J.R. Rahn said in a statement.

MindMed did not disclose what pain conditions it was developing treatments for, but it is working with researchers in Switzerland who have a Phase 2 clinical trial underway on the use of LSD to treat cluster headache. The company said it is also evaluating a second indication for a “common, often debilitating, chronic pain syndrome.”

Interest in using psychedelics to treat medical conditions has been growing in recent years. Preliminary research suggests that microdoses of LSD, psilocybin (magic mushrooms) and other psychedelics may offer a new way to treat pain. The exact mechanism in which psychedelics have an analgesic effect is not fully understood, but early research indicates that LSD can modulate serotonin receptors that help regulate pain and inflammation.

"Evidence dating back to the 1950s suggests that LSD and other psychedelics may have analgesic effects, but this treatment area remains largely untapped by companies studying psychedelics, with the majority of research focusing solely on psychiatric indications," said Rob Barrow, MindMed’s Chief Development Officer. 

The company is planning to submit a Pre-Investigational New Drug (IND) application to the Food and Drug Administration for a Phase 2a proof of concept study of LSD (lysergic acid diethylamide) in the second half of 2021.

MindMed will have to clear some high regulatory hurdles. LSD, psilocybin, MDMA (Ecstasy) and other psychedelics are classified as Schedule I controlled substances, meaning they have a high potential for abuse and currently have no accepted medical use in the United States.

Magic Mushrooms, Psychedelics and Chronic Pain

By Roger Chriss, PNN Columnist

The recent news that Denver has decriminalized “magic” mushrooms is the latest sign of growing interest in the use of psychedelics. Whether it’s microdosing mushrooms to stimulate the mind or using them to treat depression and chronic pain, psychedelic drugs are having a moment.

Magic mushrooms are any of roughly 200 different types of fungi that produce psilocybin, a hallucinogenic substance. Other psychedelics include LSD, DMT, ayahuasca and ibogaine. For reasons of chemistry and cultural baggage, DMT is generally avoided, LSD is used with extra caution and psilocybin is getting the most attention in clinical studies.

Preliminary research has found positive outcomes for psychedelic therapy in smoking cessation,  anxiety, post-traumatic stress disorder and refractory depression. And there are promising findings on psychedelics for cluster headaches and phantom limb pain.

A 2015 review in the Journal of Psychoactive Drugs reported that for patients with cluster headaches, psilocybin and other hallucinogens “were comparable to or more efficacious than most conventional medications.”  

In a 2006 Neurology review, researchers interviewed 53 cluster headache patients who used LSD or psilocybin. Most reported success in stopping cluster attacks and extending periods of remission.

And a 2018 Neurocase report described positive results for one patient with intractable phantom pain who combined psilocybin with mirror visual-feedback.

Obviously, these studies are very preliminary. Patient self-reports on drug use outside of clinical settings have limited value as evidence of efficacy. And case reports are by definition too small-scale to generalize from.

Fortunately, more clinical trials are underway for psilocybin and LSD. Last year the FDA approved a “landmark” psilocybin trial for treatment-resistant depression. And the Multidisciplinary Association for Psychedelic Studies is also working to promote robust clinical research.

Of course, psychedelics are not without risks. As described in detail in the book DMT: The Spirit Molecule, patients need to be screened and monitored before, during and after psychedelic therapy.

Michael Pollan, author of “How to Change Your Mind”, told The New York Times that psilocybin has risks “both practical and psychological, and these can be serious.”

There are also risks of conflating the pop culture phenomenon of microdosing to clinical benefits obtained under medical supervision.

The “betterment of healthy people” through microdosing is enthusiastically endorsed in books like “A Really Good Day” by Ayelet Waldman. But a 2018 placebo-controlled study on LSD microdosing found no “robust changes” in perception, mental acitivty or concentration.

The microdosing trend could stymie serious research and bias public opinion about psychedelics — just as it did in the 1960’s.

The potential for psychedelic therapy in the management of chronic pain disorders is two-fold. First, psychedelics may represent a safe and effective way to manage otherwise intractable disorders like cluster headaches and phantom limb pain. Second, psychedelics may help address the depression, PTSD and anxiety that often contribute to or accompany such disorders.

It is to be hoped that more research on psychedelics comes quickly.

Finding Validation at the Migraine Symposium

By Mia Maysack, PNN Columnist

It was an honor to attend the annual Migraine Symposium and Awards Dinner held by the Association of Migraine Disorders (AMD) this past weekend at Brown University in Providence, Rhode Island.  

At the symposium there were more than 25 experts covering topics from breakthroughs in migraine research, emerging technology, holistic treatments, medicinal cannabis and one of the most painful conditions known to mankind: cluster headaches.        

As someone who lives with multiple brain diseases and disabling chronic intractable pain, sharing space with migraine community members and healthcare professionals that sincerely care made the occasion extraordinarily meaningful to me.

I was introduced to many exceptional human beings, each of whom I could easily write a column about, but for now I'd like to shine the spotlight on the President of AMD, Dr. Frederick Godley.  Not only is he an extraordinarily intelligent and kind soul, his positive attitude illuminated the entire room

#ShadesforMigraine

Let me share one of the very first moments of validation I'd ever experienced as a person living with migraine and cluster headaches caused by post-bacterial meningitis. Having inquired with many healthcare professionals as to whether or not I am living with a traumatic brain injury (and been disregarded by each and every one), my eyes fill up with tears while rejoicing when I write that although I am not a patient of Dr. Godley or being treated by him, he acknowledged that possibility.  

At the end of the day, it doesn't do those of us coping with severe ailments much good to fixate on any specific diagnosis. What's most important is we find a way to manage whatever hand we are dealt. But the validation helps. There have been moments when I've begun to question my own sanity. There's no possible way my head could be hurting *this* bad or for *this* long. Most others are in persistent disbelief as well, even though I crack jokes that if I were to ever wake up pain free, then I must be dead!

I am grateful that I am not and tremendously excited about the future possibilities in migraine treatment. Considering that for about 30 years one of our only options was a small class of medications, now is the best time to get involved in the migraine community because we're moving forward with such momentum. There have been funds granted for much needed further research.

PTSD and Psychedelics

Some other thoughts about the symposium:

The very significant validation that post-traumatic stress disorder (PTSD) is a common underlying element of pain or even a potential cause of it. Think about it. If your own body feels as though it is fighting and turning against you on a daily basis, how are we to live without stress or experience any sense of security? 

It's not as common as it should be to go into a doctor's office and be addressed as an entire person. In my experience it has been: “Let's do what we can to mask the symptoms and settle on normalizing what’s left.” That is not treatment. Unacceptable.

The same small class of medications that are one of the only options for people living with ongoing head pain have a similar chemical makeup to Psilocybin, a psychedelic compound found in mushrooms. Psilocybin and LSD are beginning to have more credibility as potential options in treating Trigeminal Autonomic Cephalalgia (TAC) or cluster headaches. There's hope they could be helpful in treating other conditions as well, despite the fact they've got an overall reputation as being hazardous drugs. 

Ever come across a rule that just seems absolutely ridiculous? That's kind of how I feel about the current classification of these substances. We all know it only takes one person to essentially ruin things for everyone else. As a result, most people think this kind of stuff only causes harm and chaos.  No one is suggesting that anybody should go to their local drug dealer and score a bag of whatever -- we’re discussing potential. It all boils down to the science and our focus here is solely medicinally related.

Much like we've been exploring the use of CBD without THC, we are moving forward with learning more about these other substances -- potentially without the psychedelic or hallucinogen properties. Perhaps they're needed to induce relief. And if that is the case, in what micro-dosage could this possibly be prescribed in a safe, effective way?     

Although I am not using them, I've known others who’ve had successful results. In the proper way and for the right reasons, I have also chosen to advocate for them, as there seems to be far less complications with more natural options than those from the pharmaceutical realm. Each approach has its rightful place and there's no one-size-fits-all for everyone.
