Psychedelic therapies may not work always. Let me be clear. We support the current revolution in mental health that is psychedelic psychotherapy. We have been involved in MDMA research. Our clinics in the US as well as in Amsterdam provide psychedelic therapy. We also know what it means to work with these medicines in mental health. Compare this to how long, difficult, and at times impossible healing can be without them. This does not, however, guarantee a positive outcome. One of the most significant and yet invisible factors in a person’s psychedelic therapy session is their capacity for dissociation.
What is Dissociation?
Dissociation is a biological reaction we all have to overwhelming threat. It is an involuntary emotional and physical numbing response. The release of natural, endogenous opioids within the brain and nervous system causes the numbing response. In a landmark paper on the topic, PTSD researcher Dr. Bessel van der Kolk notes:
“…two decades after the original trauma, opioid-mediated analgesia developed in subjects with PTSD in response to a stimulus resembling the traumatic stressor, which we correlated with a secretion of endogenous opioids equivalent to 8 mg of morphine” .
Van der Kolk is referring to Vietnam veterans. 20 years afterwards some echo of the war (sounds, images, smells) re-exposed them to their trauma. These vets had the same numbing response that can be produced with an injection of 8 mg of morphine. Hospitals use smaller doses of opioids to treat severe breakthrough pain. This means that our internal pharmacy is secreting powerful opioids to physically, emotionally and psychologically numb us out. This occurs even decades after a trauma has taken place. This is true for war veterans. This is also true for adults who grow up in stressful, neglectful, chaotic or abusive families as children. Dissociation is not mild. It’s not invented, nor is it a placebo. It is a very real, measurable neuro-chemical shift in the brain.
Dissociation in Mental Health
To comprehend the central role of dissociation in mental health, we turn back to van der Kolk. He notes:
“…A vast literature on combat trauma, crimes, rape, kidnapping, natural disasters, accidents, and imprisonment has shown that the trauma response is bimodal:…hyper-reactivity to stimuli, and traumatic re-experiencing coexist with psychic numbing, avoidance, amnesia, and anhedonia. These responses to extreme experiences are so consistent across the different forms of traumatic stimuli that this bimodal reaction appears to be the normative response to any overwhelming and uncontrollable experience” .
Van der Kolk is saying that this combination of sympathetic nervous system fear, stress, anxiety, and panic mixed with an opioid-based, parasympathetic, dissociative numbing response is utterly common. We see it in research. We also see it every day in the trenches of mental health work.
These two sides are the hallmark of trauma. But the surprising fact is that there are no widely practiced modalities that effectively treat dissociation. You can see and feel stress. It is much more challenging to see and feel blankness. Neither your own mind nor your therapist has the training to notice, much less successfully engage dissociation.
Trauma-focused Therapies and Dissociation
For example, the EMDR protocol advises the clinician to back away from the processing phase and return to resourcing if the client begins to dissociate. Arguably one of the most well-known modalities for treating trauma was never designed to treat dissociation. Consider the ‘how bad do you feel on a scale of 0 to 10’ on the Subject Units of Distress (SUDs) assessment. Any self-report measure of distress on SUDs will completely miss and underrate significant trauma events involving dissociation. Compare this to much less severe stress events involving no dissociation, which will rate higher.
Common talk therapy or CBT has limit with what it can do for symptoms emanating from dissociated material. This is because we talk about what the mind can see. We talk about what is upsetting and can be felt. We don’t talk about or even look for what should be there but is oddly missing. This is especially true if the numbing blankness has been in a person’s life since childhood and is the water they swim in. Dissociation is the central dilemma at the heart of mental health. We don’t have good metrics for even noticing it. Nor do we have good metrics for engaging with it. Moreover, in our opinion, it is the central cause behind depression and treatment resistance.
Most people have some level of dissociation. This is almost certainly true of people considering psychedelic therapy to resolve their more treatment-resistant symptoms. It’s more a question of how much and how deep the dissociation runs.
Single Event Trauma or Lasting Pattern?
Is the client coming in for a single event trauma, like an assault or a car accident? Did dissociation occur during just that one event? Or is there prolonged, repeated, childhood neglect or abuse that happened in their family of origin? Both will create dissociation. But the latter person will likely have lived significant parts of their childhood in a dissociative state. They will typically not remember their childhood with actual specific concrete events. Rather they will have vague, abstract, generalized recollections of a ‘fine, happy’ childhood. This person will encounter much more profound dissociation during their psychedelic therapy session.
MDMA and other psychedelics do not, by their own nature, crack dissociation.
Most clients in the first scenario are typically not driven by suffering from treatment resistant symptoms. These are people with a relatively stable childhood who experienced a traumatic event later in life. Talk therapy, EMDR or standard treatment works for these clients. The same applies to those who may not have even needed therapy in the first place.
Dissociation More Likely for Complex Cases
At least for now, the psychedelic therapy client is more likely to be the complex case. Think of a PTSD, early childhood, and/or, developmental trauma patient. They hold a significant amount of dissociation in their system. First, when used skillfully they can lead to peak or mystical experiences. This involves the boundaries of the individual ego dissolving. The end result leaves one knowing that they are intimately connected through love to everything and everyone else on the planet. After having had such an experience most people find that it is much more difficult do things that are harmful to anything or anyone. This is one of the more generic outcomes of mental health research on psychedelics. This outcome shows they may be very therapeutic in treating depression, anxiety, addictions, and a variety of other mental health conditions.
Psychedelics Don’t Crack Dissociation
MDMA and other psychedelics do not, by their own nature, crack dissociation. They can significantly accelerate the clearing of it. But the process needs focus, and a guide, in order to go beyond this dissociative defense structure. Consider this scenario. You will be taking a powerful psychedelic medicine to address the pain in your life. At the same time, your neurobiology is going to release a large dose of numbing heroine-like opioids specifically to protect you from your traumatic memory. Your system has been doing this for years (perhaps even as far back as infancy). Your body is good at it, and it’s not going to stop today. Consider what might happen when a psychedelic response runs straight into an opioid response. This is where we get some variation in people’s experience.
Here is what we have seen specifically with MDMA. (But these observations apply to other psychedelics as well which we will focus on in part 2 of this article). Clients frequently feel completely sober even at the high point of a session. People will think that they received a placebo, or it’s just not working for whatever reason. They will feel like nothing is going on. They’re left with a boring feeling. This leads to thinking that they can get up and go about their day. They will simply feel no change.
Another possibility is that they may just become sleepy. If a therapist was not in the room, they might well fall asleep for a few hours on MDMA. This may be hard to fathom if you are familiar with this drug in a recreational setting. However, in a therapy session sleepiness is common. When dissociation is given room to emerge due to focusing on a traumatic memory, this occurs. Just like antipsychotic medication will prevent a psychedelic response, our endogenous opioids also have the power to shut things down.
The Mind Ascribes Meaning
The conscious, storytelling, meaning-making mind will often ascribe meaning to this experience. For example, the mind may say ‘I knew nothing would ever work for me’ or ‘The medicine is telling me…’. There are all sorts of conceptual stories we can generate on top of what is happening. But the core experience is one of ‘nothing much is going on’.
The trick to working with dissociation is not to ignore the gold that is boredom in favor of other juicy bits that are more interesting to the mind. The client and the therapist will have an impulse to provide something evocative to get the session going. But the trick is to bring the nothingness, the blank, flat, sobriety, or sleepiness into focus. Have the client notice all the details of boredom. Doing so will take a lot of trust. Just know the blankness is incredibly valuable.
The seeming non-response is the access point to go deeper. Psychedelics, including cannabis and MDMA have many gifts. One is that they generate a profoundly embodied, visceral, ‘here and now’ experiences. In this case, the very real ‘here and now’ reality that the medicine brings up is dissociation. It is a blanked out, unfeeling state. Our recommendation is to stay with that experience even though it does not fit the client’s idea of how the session should be. Again, easier said than done. Realize the psychedelic therapy client has so much hope. They expect that this treatment will work and be the one thing that helps.
The seeming non-response is the access point to go deeper.
Boredom Will Fade
Eventually, the blank boredom will crack. It might take staying with it for 30 minutes. It might take 2 hours, or the entire session. Eventually, it will crack. When it does, there is an entire universe underneath that was being hidden from awareness by the dissociation. Therapy can now engage this material since it has become visible. Remember, the reason why the dissociation became active in the first place was that overwhelming experiences were taking place. These overwhelming and impossible experiences are what the client fully believes they couldn’t survive when they were happening. Certainly, they were not digestible, integratable experiences at the time and were partitioned off.
Your mind organizes itself well, not to see dissociation. Your mind develops all sorts of interesting, often repeating distractions that keep looping you around in the session(s). These can be an even a more exaggerated form of the defensive looping that we see in non-psychedelic therapy. There is a lot of other material and channels to focus on that will seem interesting to you. But these are mostly just a distracting puppet show put on by your mind to keep the dissociation in place.
Dissociation May Not Surface
The other possibility is that dissociation doesn’t appear. This happens because most people who have traumatic events residing in dissociation also have many other more surface events that are appropriately available to be worked with. Events that were not so overwhelming that they generate an opioid response. Instead, these events were milder and thus create disturbing anxiety and fear responses that are visible to awareness.
Essentially, many clients are in a target-rich environment for both dissociation as well as garden-variety stress events. Ketamine, MDMA, and cannabis are very effective at clearing out these more available-to-consciousness surface experiences. PTSD scores generally will go down. Clients will feel a lot better for some significant period of months or years. However, the work and, unfortunately, the symptoms are typically not done yet. There is a lot of short-term benefit. However, the material that was hanging out in dissociation will begin to bubble to the surface. This happens because you are ultimately more healthy, resourced, and trusting of the process.
In this condition, your entire system is more trusting and faces less compromise. It may be weeks or months later but at some point, previously dissociated material will begin to emerge. It is not a sign that your previous psychedelic sessions failed. Quite the opposite. It is a sign of a person’s innate health that their system wants to keep excavating and processing until completion.
Read Part 2 of Why Psychedelic Therapies May Not Work
In part 2 of this article, we’ll talk about how dissociation interacts with psilocybin (psychedelic mushrooms) assisted therapy. We reference our experience in our Amsterdam program. We include interviews with clinicians who are part of the Psychedelic Society of the Netherlands who regularly use psilocybin in their therapy practice.
