Using machine learning analysis, researchers have determined that a mystical and insightful psychedelic drug experience may be linked to long-term reductions in anxiety and depression symptoms.

The study is the first to characterise subtypes of the subjective psychedelic experience and link them to mental health outcomes.

The team utilised machine learning to analyse data from almost 1,000 respondents to a survey about their previous non-clinical experiences with psychedelic drugs.

The analysis suggests that individuals who scored the highest on questionnaires assessing the mystical and insightful nature of their experiences consistently reported improvements in their anxiety and depression symptoms.

The research has been published in the Journal of Affective Disorders.

Study findings

The data also found that a challenging experience while taking psychedelics – such as one that feels frightening – can have beneficial results, especially in the context of mystical and insightful experiences. 

The researchers suggest this could be helpful for practitioners to know as they guide patients through clinical trials testing psychedelics’ therapeutic potential.

Senior author Alan Davis, assistant professor and director of the Center for Psychedelic Drug Research and Education in The Ohio State University College of Social Work, commented: “Sometimes the challenge arises because it’s an intensely mystical and insightful experience that can, in and of itself, be challenging.

“In the clinical research setting, folks are doing everything they can to create a safe and supportive environment. But when challenges do come up, it’s important to better understand that challenging experiences can actually be related to positive outcomes.”

The 985 participants whose responses were analysed in this study described substances they had used and completed questionnaires evaluating the extent to which their psychedelic experience was mystical, psychologically insightful, or challenging.

Outcomes assessed in the survey included depression and anxiety symptom levels and ratings of satisfaction with life and psychological flexibility – one’s capacity to act in ways that are consistent with their values regardless of whatever internal or external experience they might have – before and after using the psychedelic.

The sample included users of psilocybin, LSD, Ayahuasca, mescaline, peyote cactus and 5-MeO-DMT, with the estimated dose level of the single drug use they recalled.

“The group that had the highest insightful and mystical experiences and low challenging experiences showed the most benefit in terms of remission of anxiety and depression symptoms and other longer lasting benefits to their life,” said first author Aki Nikolaidis, an affiliate of Ohio State’s Center for Psychedelic Drug Research and Education (CPDRE) and a research scientist in the Center for the Developing Brain at the Child Mind Institute.

Psilocybin and LSD

Data analysed from participants who had used psilocybin and LSD showed that the same patterns emerged: Three distinct subtypes that were associated with the same outcomes, including benefits to mental health even after a challenging experience. 

That replication speaks to the importance of the subjective experience for psychedelics users, Nikolaidis said.

“Identifying subtypes that exist regardless of which psychedelic you take answers an interesting question,” he said. 

“But the fact that we found that they’re associated with specific outcomes, and replicated that finding, really shows why it’s important to understand the powerful nature of what is happening subjectively and its potential to yield a beneficial outcome.”

The researchers noted that a number of trends stood out, including: 

The positive scoring group whose experience could be considered optimal – high scores on mysticism and insight and low scores on challenges – tended to be younger than participants in the other groups. 

Among individuals who scored highest on challenging experiences, there was a higher proportion of people who had taken large doses of the psychedelic drugs. 

The low scoring subtype had lower psychological flexibility, anxiety and depression scores before the psychedelic experience, and lower improvements in those symptoms and satisfaction with life than the other two subtypes.

Davis said he will be watching to see if these subtypes of experiences apply in the clinical setting, where psilocybin-assisted therapy is being studied at Ohio State for the treatment of post-traumatic stress disorder among military veterans.

“Finding the variety of other outcomes that these subtypes might be related to is an interesting next step,” he said. 

“These could include adaptive or functional outcomes in people’s quality of life or well-being, or a better understanding of their life’s purpose or relationships.”

The work was supported by the Brain and Behavior Research Foundation, the National Institute of Mental Health, the CPDRE, the Steven & Alexandra Cohen Foundation, and private donors.

Additional co-authors include Rafaelle Lancelotta of Ohio State, and Natalie Gukasyan, Roland Griffiths and Frederick Barrett of the Center for Psychedelic & Consciousness Research at Johns Hopkins School of Medicine, where Davis is also an affiliate.

Is connection key? How clinicians impact patient outcomes in psychedelic therapy

Published

on

A wealth of research is showing how psychedelic-assisted therapy holds promise for the treatment of mental health conditions such as depression, but what role does the therapist play in a patient’s outcome? A new study has suggested it may be a big one.

Psychedelics have piqued huge interest due to their effects on the brain. Research points to their ability to induce neuroplasticity in the brain as one of the key reasons they may help with conditions such as depression and anxiety.

However, set – the individual’s (or patient’s) mental state – and setting – the individual’s environment during a psychedelic experience – are hugely impactful on the outcome of these experiences.

In the traditional use of psychedelic medicines, shamans help to guide set and setting throughout the experience with singing, drumming and ritual. Today, in scientific research, trials, and in clinics, the clinician is essentially playing this role.

Senior author of a new study, Alan Davis, associate professor and director of the Center for Psychedelic Drug Research and Education in The Ohio State University College of Social Work, has highlighted that the impact of clinicians on patient outcomes is not new, with research consistently showing that a trusting relationship between patients and clinicians has been key to better outcomes. This concept is known as a “therapeutic alliance”.

Understanding the therapeutic alliance

To find out more about the impact of this therapeutic alliance in psychedelic therapy, researchers from Ohio State University College of Medicine analysed data from a clinical trial that investigated psilocybin-assisted psychotherapy for the treatment of major depressive disorder (MDD).

In the trial, participants received two doses of psilocybin and 11 hours of psychotherapy, completing a therapeutic alliance questionnaire afterward, which assessed the strength of the therapist-participant relationship.

Participants also completed questionnaires about any mystical and psychologically insightful experiences they had during the drug treatment sessions. In psychedelic research, the mystical experience has often been shown to be related to the continuing positive effects of this therapy.

The Ohio team looked at the depression outcomes alongside patient reports about their experiences with the medicines as well as their connection with their therapists.

They found that a stronger relationship between patient and clinician led to a better clinical outcome for the patient – with improved depression scores up to 12 months following the experience.

Lead author Adam Levin, a psychiatry and behavioral health resident at Ohio State University College of Medicine, stated: “What persisted the most was the connection between the therapeutic alliance and long-term outcomes, which indicates the importance of a strong relationship.”

Analysis results revealed that over time, the alliance score increased, and in fact demonstrated more acute mystical experiences for the patient. The team also found that acute effects were linked to lower depression four weeks following treatment, but were not associated with better depression outcomes a year after the trial.

“The mystical experience, which is something that is most often reported as related to outcome, was not related to the depression scores at 12 months,” Davis stated.

“We’re not saying this means acute effects aren’t important – psychological insight was still predictive of improvement in the long term. But this does start to situate the importance and meaning of the therapeutic alliance alongside these more well-established effects that people talk about.”

According to the team, the analysis showed that a stronger relationship during the final therapy preparation session predicted a more mystical and psychologically insightful experience – which in turn was linked to further strengthening the therapeutic alliance.

“That’s why I think the relationship has been shown to be impactful in this analysis – because, really, the whole intervention is designed for us to establish the trust and rapport that’s needed for someone to go into an alternative consciousness safely,” Davis stated.

“This isn’t a case where we should try to fit psychedelics into the existing psychiatric paradigm – I think the paradigm should expand to include what we’re learning from psychedelics,” Levin added.

“Our concern is that any effort to minimise therapeutic support could lead to safety concerns or adverse events. And what we showed in this study is evidence for the importance of the alliance in not just preventing those types of events, but also in optimizing therapeutic outcomes.”

The authors emphasised that efforts to minimise negative experiences in future studies of psychedelics is vital, and that therapy is critical to creating a supportive environment for patients.

Phase 2a trial to investigate 5-MeO-DMT candidate for alcohol use disorder

Published

on

Beckley Psytech and Clerkenwell Health are collaborating on a Phase 2a trial investigating Beckley’s synthetic 5-MeO-DMT candidate combined with psychological support as a treatment for alcohol use disorder (AUD).

AUD is estimated to affect around 237 million people across the globe and over 7.5 million people in the UK.

Treatment options for the harmful use of alcohol are not always effective – there are high relapse rates and there are around three million deaths each year attributed to the substance’s misuse.

Increasing research is showing that psychedelics may hold promise as innovative treatments for addiction, including substances such as ketamine and psilocybin.

BPL-003 is Beckley Psytech’s short-duration and fast-acting synthetic formulation of 5-MeO-DMT – a psychedelic found in several plant species and the glands of at least one toad species – which is administered intranasally via an FDA-approved delivery device.

The compound has shown in Phase I data to be well-tolerated with a reproducible and dose-linear pharmacokinetic profile.

The Phase 2a trial

Beckley and Clerkenwell have confirmed that the collaborative Phase 2a open-label trial will evaluate the safety, tolerability and pharmacodynamic effects of a single dose of Beckley BPL-003 combined with abstinence-oriented psychological support in participants with AUD.

Currently taking place at King’s College London, Clerkenwell Health’s clinic near Harley Street, London, will provide an additional trial site.

According to Beckley, BPL-003 has been successful in eliciting psychedelic experiences of “similar intensity but shorter duration than psilocybin”.

Dr Henry Fisher, Chief Scientific Officer at Clerkenwell Health, stated: “An estimated 600,000 people are dependent on alcohol in England. This, coupled with an alarming increase in alcohol-related deaths of 89% over the past 20 years, shows the status quo isn’t working.

“Conventional treatments for alcohol dependency aren’t producing meaningful improvements and new avenues must be explored. This trial will assess whether psychedelic-assisted treatment can be an effective therapy for alcohol use disorder, with the hope of rolling out the treatment widely.

“Health professionals and policymakers should seriously consider such treatments, which could be genuinely ground-breaking for the NHS and for the hundreds of thousands of people being treated for alcohol use disorder in the UK.”

Beckley Psytech and Clerkenwell have emphasised that the results of the trial may be used to provide support for further study of psychedelic-assisted treatment for alcohol dependency.

Dr Rob Conley, Chief Medical and Scientific Officer at Beckley Psytech, added: “We’re committed to developing a transformative and effective treatment option for individuals struggling with alcohol use disorder.

“Based on our preclinical and Phase I data, we are optimistic about the potential therapeutic benefits of BPL-003 for substance use disorders and we are excited to evaluate the compound further in this clinical trial.

“I want to extend my thanks to the team at Clerkenwell Health and King’s, as well as to the patients who have joined, and will join, this study. Their participation, support and collaboration are absolutely critical to furthering research into this area of huge unmet need.”

The Entourage Effect in Mushrooms: Natural psilocybin may outperform synthetic

The Entourage Effect in Mushrooms: Natural psilocybin may outperform synthetic

A new study from the Hebrew University-Hadassah Medical Center has indicated that natural psilocybin extracts may demonstrate superior efficacy to synthetic psilocybin extracts.

Recent years have seen a boom in research into psilocybin for the treatment of mental health conditions such as anxiety and depression.

Many of the clinical trials investigating psilocybin use synthetic extracts rather than natural ones. This is because synthetic extracts will contain psilocybin alone, whereas natural psilocybe mushroom extracts will contain several different compounds such as psilocybin, psilocin, baeocystin and norbaeocystin.

Having multiple compounds can pose a challenge when running clinical trials as identifying which compounds are active and what their impact is becomes difficult to measure, and the concentrations of these compounds can vary depending on factors such as growth conditions and processing techniques.

This makes the standardisation of multi-compound medicines a huge challenge, as medicine consistency, reproducibility and dosing become difficult. However, these are essential factors when it comes to conducting clinical trials and receiving approval for medicines from regulators.

The Entourage Effect

In 2011 Dr Ethan Russo put forward the theory of the Entourage Effect in cannabis. 

The cannabis plant contains over 400 different cannabinoids that have so far been identified, such as THC, CBD, CBN and CBG.

Russo hypothesised that these different cannabinoid compounds work synergistically to create a therapeutic effect, as opposed to compounds such as THC or CBD working in isolation.

This hypothesis has been touched on only a few times in the scientific literature in relation to psychedelic mushrooms.

For example, in Dr Jochen Gartz’s 1989 paper ‘Biotransformation of tryptamine derivatives in mycelial cultures of Psilocybe’ which proposed a synergistic relationship between compounds in the mushrooms, and a 2015 paper by Zhuck et al, ‘Research on Acute Toxicity and the Behavioral Effects of Methanolic Extract from Psilocybin Mushrooms and Psilocin in Mice’, which observed that the effect of psychedelic mushroom extracts on mice was much stronger than pure psilocybin.

There has been very limited research on this hypothesis in mushrooms since. 

A new study: Natural may outperform synthetic

Now, a research team from Hebrew University-Hadassah Medical Center BrainLabs Center for the Psychedelic Research have compared a natural psilocybin extract to a chemically synthesised version.

Published in Molecular Psychiatry, results from the study indicate that the natural extract increased the levels of synaptic proteins associated with neuroplasticity in key brain regions, including the frontal cortex, hippocampus, amygdala, and striatum.

The ability of psilocybin to induce neuralplasticity has been indicated as one of the key features that contribute to its therapeutic effects.

The researchers suggest that these new study results indicate that nautral psilocybin extracts may offer unique therapeutic effects that may not be not achievable with synthesised, single-compound psilocybin alone. 

Metabolomic analyses also revealed that the natural extract exhibited a distinct metabolic profile associated with oxidative stress and energy production pathways.

The researchers write: “In Western medicine, there has historically been a preference for isolating active compounds rather than utilising extracts, primarily for the sake of gaining better control over dosages and anticipating known effects during treatment. The challenge with working with extracts lay in the inability, in the past, to consistently produce the exact product with a consistent compound profile. 

“Contrastingly, ancient medicinal practices, particularly those attributing therapeutic benefits to psychedelic medicine, embraced the use of extracts or entire products, such as consuming the entire mushroom. Although Western medicine has long recognised the “entourage” effect associated with whole extracts, the significance of this approach has gained recent prominence.”

However, compared to cannabis, the researchers suggest that mushroom extracts present a unique case, as they are highly influenced by their growing environment such as substrate, light exposure temperature and more.

“Despite these influences, controlled cultivation allows for the taming of mushrooms, enabling the production of a replicable extract,” the team writes.

The researchers emphasise that this research underscores the superiority of extracts with diverse compounds, and also highlights the feasibility of incorporating them into Western medicine due to the controlled nature of mushroom cultivation.
