LSD-assisted psychotherapy for anxiety associated with a life-threatening disease: A qualitative study of acute and sustained subjective effects

Abstract

Objective: A recently published study showed the safety and efficacy of LSD-assisted psychotherapy in patients with anxiety associated with life-threatening diseases. Participants of this study were included in a prospective follow-up.

Method: 12 months after finishing LSD psychotherapy, 10 participants were tested for anxiety (STAI) and participated in a semi-structured interview. A Qualitative Content Analysis (QCA) was carried out on the interviews to elaborate about LSD effects and lasting psychological changes.

Results: None of the participants reported lasting adverse reactions. The significant benefits as measured with the STAI were sustained over a 12-month period. In the QCA participants consistently reported insightful, cathartic and interpersonal experiences, accompanied by a reduction in anxiety (77.8%) and a rise in quality of life (66.7%). Evaluations of subjective experiences suggest facilitated access to emotions, confrontation of previously unknown anxieties, worries, resources and intense emotional peak experiences à la Maslow as major psychological working mechanisms. The experiences created led to a restructuring of the person’s emotional trust, situational understanding, habits and world view.

Conclusions: LSD administered in a medically supervised psychotherapeutic setting can be safe and generate lasting benefits in patients with a life-threatening disease. Explanatory models for the therapeutic effects of LSD warrant further study.

Synesthesias in the context of hallucinogen-induced persistent perception disorder following the use of lsd

Abstract

The hallucinogen-induced persistent perception disorder (hppd) is a disturbing complication resulting from the use of hallucinogens. We report on a case-study in which an artist suffering from visual, auditory and olfactory hallucinations also experienced chromatic-phonemic synesthesias that had persisted for two years after he had stopped using lysergic acid diethylamide (lsd). The case described demonstrates that individuals suffering from hppd can also experience synesthesias that may in fact differ phenomenologically from ‘coloured hearing’, which is a symptom known to occur in the context of substance abuse.

Back to the future: A return to psychedelic treatment models for addiction

Abstract

The discovery of the 5HT2aR agonist hallucinogen (i.e. classic psychedelic) lysergic acid diethylamide (LSD) by Albert Hofmann in 1943 was a global watershed event. Not only did it spark wide interest in the nature of consciousness and the role of neurotransmission in brain function, it opened new avenues of potential treatment for a range of mental health conditions (Hofmann, 2013). The scientific community of the 1950s through the early 1970s responded to Hofmann’s discovery by producing more than 1000 manuscripts describing the treatment of 40,000 patients (Nutt et al., 2013). Despite promising if not remarkable indications of efficacy (Krebs and Johansen, 2012; Savage and McCabe, 1973),sensationalized reports of recreational LSD use prompted legal restrictions that ultimately rendered research with LSD and …

LSD enhances suggestibility in healthy volunteers

Abstract

Rationale
Lysergic acid diethylamide (LSD) has a history of use as a psychotherapeutic aid in the treatment of mood disorders and addiction, and it was also explored as an enhancer of mind control.

Objectives
The present study sought to test the effect of LSD on suggestibility in a modern research study.

Methods
Ten healthy volunteers were administered with intravenous (i.v.) LSD (40–80 μg) in a within-subject placebo-controlled design. Suggestibility and cued mental imagery were assessed using the Creative Imagination Scale (CIS) and a mental imagery test (MIT). CIS and MIT items were split into two versions (A and B), balanced for ‘efficacy’ (i.e. A≈B) and counterbalanced across conditions (i.e. 50 % completed version ‘A’ under LSD). The MIT and CIS were issued 110 and 140 min, respectively, post-infusion, corresponding with the peak drug effects.

Results
Volunteers gave significantly higher ratings for the CIS (p = 0.018), but not the MIT (p = 0.11), after LSD than placebo. The magnitude of suggestibility enhancement under LSD was positively correlated with trait conscientiousness measured at baseline (p = 0.0005).

Conclusions
These results imply that the influence of suggestion is enhanced by LSD. Enhanced suggestibility under LSD may have implications for its use as an adjunct to psychotherapy, where suggestibility plays a major role. That cued imagery was unaffected by LSD implies that suggestions must be of a sufficient duration and level of detail to be enhanced by the drug. The results also imply that individuals with high trait conscientiousness are especially sensitive to the suggestibility-enhancing effects of LSD.

Acid Test: LSD, Ecstasy, and the Power to Heal

It’s no secret that psychedelic drugs have the ability to cast light on the miraculous reality hidden within our psyche. Almost immediately after the discovery of LSD less than a hundred years ago, psychedelics began to play a crucial role in the quest to understand the link between mind and matter. With an uncanny ability to reveal the mind’s remote frontiers and the unmapped areas of human consciousness, LSD and MDMA (better known as Ecstasy) have proven extraordinarily effective in treating anxiety disorders such as PTSD—yet the drugs remain illegal for millions of people who might benefit from them.

Anchoring Tom Shroder’s Acid Test are the stories of Rick Doblin, the founder and executive director of the Multidisciplinary Association for Psychedelic Studies (MAPS), who has been fighting government prohibition of psychedelics for more than thirty years; Michael Mithoefer, a former emergency room physician, now a psychiatrist at the forefront of psychedelic therapy research; and his patient Nicholas Blackston, a former Marine who has suffered unfathomable mental anguish from the effects of brutal combat experiences in Iraq. All three men are passionate, relatable people; each flawed, each resilient, and each eccentric, yet very familiar and very human.

Acid Test covers the first heady years of experimentation in the fifties and sixties, through the backlash of the seventies and eighties, when the drug subculture exploded and uncontrolled use of street psychedelics led to a PR nightmare that created the drug stereotypes of the present day. Meticulously researched and astoundingly informative, this is at once a personal story of intertwining lives against an epic backdrop, and a compelling argument for the unprecedented healing properties of drugs that have for decades been characterized as dangerous, illicit substances.

Tom Shroder has been an award-winning journalist, writer and editor for more than 30 years.

Here and now: Discovering the sacred with entheogens

Abstract

Renewed research with entheogens (psychedelic substances) has been able to facilitate the occurrence of mystical forms of consciousness in healthy volunteers with a high degree of reliability. This article explores the potential significance of this development for religious scholars, especially those interested in the study of mysticism. The definition of “mystical consciousness” employed in this research is presented and differentiated from visionary/archetypal and other types of alternative mental states. The ways in which entheogens may be employed with skill and maximum safety are discussed. Implications for clarifying confusion in the study of mysticism are considered, along with suggestions for future religious research on this frontier of knowledge.

Entheogens, Mysticism, and Neuroscience

Abstract

Entheogens or psychedelic drugs such as lysergic acid diethylamide (LSD) and psilocybin are associated with mystical states of experience. Drug laws currently limit research, but important new work is under way at major biomedical research facilities showing that entheogens reliably occasion mystical experiences and thereby allow research into brain states during these experiences. Are drug-occasioned mystical experiences neurologically the same as more traditional mystical states? Are there phenomenological and theological differences? As this research goes forward and the public becomes more widely aware of its achievements, religious scholars and experts in science and religion will be called upon to interpret the philosophical and theological presuppositions that underpin this research and the significance of the findings that flow from it.

Recent advances in the neuropsychopharmacology of serotonergic hallucinogens

Abstract

Serotonergic hallucinogens, such as (+)-lysergic acid diethylamide, psilocybin, and mescaline, are somewhat enigmatic substances. Although these drugs are derived from multiple chemical families, they all produce remarkably similar effects in animals and humans, and they show cross-tolerance. This article reviews the evidence demonstrating the serotonin 5-HT2A receptor is the primary site of hallucinogen action. The 5-HT2A receptor is responsible for mediating the effects of hallucinogens in human subjects, as well as in animal behavioral paradigms such as drug discrimination, head twitch response, prepulse inhibition of startle, exploratory behavior, and interval timing. Many recent clinical trials have yielded important new findings regarding the psychopharmacology of these substances. Furthermore, the use of modern imaging and electrophysiological techniques is beginning to help unravel how hallucinogens work in the brain. Evidence is also emerging that hallucinogens may possess therapeutic efficacy.

Pharmacology of Hallucinations: Several Mechanisms for One Single Symptom?

Abstract

Hallucinations are complex misperceptions, that principally occur in schizophrenia or after intoxication induced by three main classes of drugs: psychostimulants, psychedelics, and dissociative anesthetics. There are at least three different pharmacological ways to induce hallucinations: (1) activation of dopamine D2 receptors (D2Rs) with psychostimulants, (2) activation of serotonin 5HT2A receptors (HT2ARs) with psychedelics, and (3) blockage of glutamate NMDA receptors (NMDARs) with dissociative anesthetics. In schizophrenia, the relative importance of NMDAR and D2R in the occurrence of hallucinations is still debated. Slight clinical differences are observed for each etiology. Thus, we investigated whether the concept of hallucination is homogenous, both clinically and neurobiologically. A narrative review of the literature is proposed to synthesize how the main contributors in the field have approached and tried to solve these outstanding questions. While some authors prefer one explanatory mechanism, others have proposed more integrated theories based on the different pharmacological psychosis models. In this review, such theories are discussed and faced with the clinical data. In addition, the nosological aspects of hallucinations and psychosis are addressed. We suggest that if there may be common neurobiological pathways between the different pharmacological systems that are responsible for the hallucinations, there may also be unique properties of each system, which explains the clinical differences observed.

Autism and LSD-25 – Freeing the Most Imprisoned Minds?

In the early sixties, a number of controversial clinical investigations were published involving the administration of LSD-25 (lysergic acid diethylamide) to young children said to suffer from severe forms of autism, or childhood-onset schizophrenia (COS), which were then regarded as closely related [1]. The reason for conducting the studies with young children was the supposed similarity between autism and COS. Prompted by the apparent results of studies conducted with LSD-25 and adult mute catatonic patients by Cholden, Kurland, and Savage (1955), hypotheses were constructed to research a possible therapeutic utility. “The goal in these therapeutic efforts”, said Bender in an article published in Recent Advances in Biological Psychiatry (1962), “has been to modify the secondary symptomatology associated with retarded, regressed, and disturbed behavior of the children”. The larger part of the children treated with LSD in these studies were between six and ten years old and completely unresponsive to all other forms of treatment. That the children couldn’t be treated by other means served, in part, for the justification for using a powerful psychoactive substance in child experiments. Surely this decision would have been criticized by the ethical commission today.

A pharmacological intervention by means of LSD was said to “nudge the lagging maturation” (Bender, 1962) into a (somewhat) normal developmental pattern. How exactly the administration of LSD would accomplish the “freeing of the most imprisoned minds” was still unknown (Mogar & Aldrich, 1969). LSD was supposed to achieve success through “breaking through the autistic defense” (Bender, 1963), and in this way be exceptionally helpful in “areas which are closely related to the process of psychotherapy” (Simmons et al., 1966). Some believed LSD was especially useful at helping patients to “unblock” repressed subconscious material through other psychotherapeutic methods (Cohen, 1959). Therapists took LSD to establish a connection with the experience of schizophrenia. “During the ‘model psychosis’ phase of LSD research when the psychedelic state was considered a chemically-induced schizophrenia”, says pioneer LSD researcher Stanislav Grof (1980), “LSD sessions were recommended as reversible journeys into the experiential world of psychotics which had a unique didactic significance”.

Some researchers, like Freedman et al. (1963), studied LSD for its supposed psychotomimetic (psychotogenic) properties, meaning that the drug mimics the symptoms of psychosis, including delusions and/or delirium, as opposed to merely hallucinations (Sewell et al., 2009). An exacerbation of ‘typical’ symptoms meant an opportunity for studying the (child)schizophrenic condition. Other researchers (Bender et al., 1963; Rolo, et al., 1965) considered the neurological mechanism behind the effect of LSD, which in that time was still highly obscure, as more important than its role as facilitator of the therapeutic process. For instance, LSD attracted theoretical interest as a serotonin inhibitor and an autonomic nervous system stimulant. Bender et al. (1963) concluded that “LSD-25 given daily in oral doses of 100 mcg [2] to pre-puberty autistic schizophrenic children appears to be an effective autonomic and central nervous system stimulant”, and that these changes “appear to be chronic with continuous administration of the drug”. Continuous administration consisted of daily administration over prolonged periods of time, varying from days to several weeks . The most persistent effects of LSD-25 therapy that were published included improved speech behavior, increased emotional responsiveness, positive mood (laughter) and a decrease of compulsions.

But alas, however interesting and attractive these results seemed to be — the evidence didn’t stick. Today studies into the relationship of LSD and autism aren’t being conducted and the results that were produced are regarded as highly controversial, if not completely repudiated. This was in part because, in retrospect, the studies were greatly flawed. The researchers seemed to have brushed over the conceptual controversy too quickly by choosing “not to deal with the controversial issues concerning the definitions and etiological factors of either childhood schizophrenia (1) or the autistic reaction pattern (2)” (Bender et al., 1962). The debate about the correct place of (childhood) autism within the DSM (Diagnostic and Statistical Manual of Mental Disorders) remains problematic to this day (DSM-V), but autism has long been divorced from the umbrella of schizophrenia. Although both disorders share clinical features, clinical psychologists and psychiatrists regard autism to be a separate diagnostic ‘entity’ from schizophrenia. Because LSD was used as a drug for “intensifying pre-existing symptomology” of schizophrenia (Bender et al., 1962), a conceptual detachment from autism would have disturbed the foundation of the results.

Even if the researchers had chosen to ‘deal with the controversy’, in hindsight, sampling would have still ended up being very problematic. The children treated were demographically varied and covered a broad age range. Conflicting significance is given to the relationship between age and drug response, but Bender noted that “in contrast to pre- adolescents, younger children manifest consistently different reactions” (1962). In contrast, Fisher and Castile concluded that “older children were better candidates for psychedelic therapy because verbal communication was possible and also because they tended to be less withdrawn, more schizophrenic than autistic, and displayed more blatant symptomology” (Mogar & Aldrich, 1969). In addition to age, also the symptoms of treated children were heterogeneous and weren’t corrected for severity. There was no randomization, and most studies suffered from fluctuating frequency of administration and dosage. Lastly, the set and setting of the experiments varied strongly.

Although the studies conducted in the sixties had major flaws from an experimental point of view and therefore didn’t hold up to scientific scrutiny, Mogar and Aldrich argue in an article published in Behavioral Neuropsychiatry (1969) that the results considered as a whole do point to a utility of administering LSD to autistic children. “The significance of seemingly contradictory results”, say Mogar and Aldrich, “has often been obscured by the persistent search for static, ‘drug-specific’ reactions to LSD”. This is an interesting point; despite that the results don’t indicate significance in an experimental sense, there may still be a therapeutic utility. Mogar and Aldrich report that the greatest therapeutic benefit was related to “(a) the degree of active therapist involvement with the patient; (b) an opportunity to experience meaningful objects and interpersonal activities; and (c) congenial settings that were reasonably free of artificiality, experimental or medical restrictions, and mechanically administered procedures” (1969). In practice clinical therapy is usually far removed from theory. It could be that testing LSD, itself being a highly unpredictable drug, in combination with the therapy dynamic is too hard to substantiate. Mogar and Aldrich conclude that “the administration of LSD is inextricably embedded in a larger psychosocial process which should be optimized in accordance with particular treatment goals”.

Considering the recent growth of interest into this area of research, these older and rather obscure studies deserve to be excavated from the psychedelic research literature. Researchers at LA BioMed (Los Angeles Biomedical Research Institute) are now constructing a study which is said to test the already established anecdotal therapeutic relationship between MDMA (3,4-methylenedioxy-N-methylamphetamine) and autism in adults. The study is the latest in an expanding program of research into the therapeutic use of MDMA funded by the nonprofit Multidisciplinary Association for Psychedelic Studies (MAPS). “This new study will give us a chance”, says Charles Grob head researcher at LA BioMed (2014), “to determine the actual effects of differing dosages of medication that we know for certain is pure MDMA on adults on the autism spectrum. If the results of this research warrant further investigation, data from this study will be used to design additional clinical trials”. Now that the limitations for research into the psychedelic experience and its therapeutic effects are being removed and LSD is once again an object of study, these previously published results could serve for the production of new hypotheses.
