Effects of mescaline and lysergic acid (d-LSD-25)

The effects of mescaline and lysergic acid were studied in schizophrenic patients. It was found that physiological changes were produced in these patients and that their mental symptomatology was markedly aggravated. The observations made with the above-mentioned drugs on normal individuals were compared with those seen in schizophrenic patients. Mescaline and lysergic acid are drugs that disorganize the psychic integration of a person. This disorganization is much more apparent in schizophrenics than in normals. The diagnostic, prognostic, and therapeutic use of these drugs is also discussed.

Hallucinogens

Abstract

Hallucinogens (psychedelics) are psychoactive substances that powerfully alter perception, mood, and a host of cognitive processes. They are considered physiologically safe and do not produce dependence or addiction. Their origin predates written history, and they were employed by early cultures in a variety of sociocultural and ritual contexts. In the 1950s, after the virtually contemporaneous discovery of both serotonin (5-HT) and lysergic acid diethylamide (LSD-25), early brain research focused intensely on the possibility that LSD or other hallucinogens had a serotonergic basis of action and reinforced the idea that 5-HT was an important neurotransmitter in brain. These ideas were eventually proven, and today it is believed that hallucinogens stimulate 5-HT2A receptors, especially those expressed on neocortical pyramidal cells. Activation of 5-HT2A receptors also leads to increased cortical glutamate levels presumably by a presynaptic receptor-mediated release from thalamic afferents. These findings have led to comparisons of the effects of classical hallucinogens with certain aspects of acute psychosis and to a focus on thalamocortical interactions as key to understanding both the action of these substances and the neuroanatomical sites involved in altered states of consciousness (ASC).

The 5-HT2A receptor clearly plays an essential role in cognitive processing, including working memory, and ligands for this receptor may be extremely useful tools for future cognitive neuroscience research. In addition, it appears entirely possible that utility may still emerge for the use of hallucinogens in treating alcoholism, substance abuse, and certain psychiatric disorders.

Clonazepam treatment of lysergic acid diethylamide-induced hallucinogen persisting perception disorder with anxiety features.

Abstract

An unique and intriguing characteristic of lysergic acid diethylamide (LSD) and LSD-like substances is the recurrence of some of the symptoms which appear during the intoxication, in the absence of recent intake of hallucinogens. Hallucinogen persisting perception disorder (HPPD) is a condition in which the re-experiencing of one or more perceptual symptoms causes significant distress or impairment in social, occupational or other important areas of functioning and may be extremely debilitating. Benzodiazepines are one of the recommended agents for the treatment of HPPD but it is unclear which of them may be more helpful. The goal of our investigation was to assess the efficacy of clonazepam in the treatment of LSD-induced HPPD. Sixteen patients fulfilled entrance criteria. All complained of HPPD with anxiety features for at least 3 months and were drug free at least 3 months. They received clonazepam 2 mg/day for 2 months. Follow-up was continued for 6 months. They were weekly evaluated during the 2 months of clonazepam administration and monthly during the follow-up period using the Clinical Global Impression Scale, a Self-report Scale and Hamilton Anxiety Rating Scale. Patients reported a significant relief and the presence of only mild symptomatology during the clonazepam administration. This improvement was clearly sustained and persisted during a 6-month follow-up period. This study suggests that high potency benzodiazepines like clonazepam, which has serotonergic properties, may be more effective than low-potency benzodiazepines in the treatment of some patients with LSD-induced HPPD.

Flashback and Hallucinogen Persisting Perception Disorder: clinical aspects and pharmacological treatment approach.

Abstract

One unique characteristic of lysergic acid diethylamide (LSD) and LSD-like substances is the recurrence of some of the symptoms which appeared during the intoxication after the immediate effect of the hallucinogen has worn off. This recurring syndrome, mainly visual, has not been clearly understood, appreciated or distinguished from other clinical entities by clinicians. The terms Flashback and Hallucinogen Persisting Perception Disorder (HPPD) are used interchangeably in the professional literature. Flashback is a usually short-term, non-distressing, spontaneous, recurrent, reversible and benign condition accompanied by a pleasant affect. In contrast, HPPD is a generally long-term, distressing, spontaneous, recurrent, pervasive, either slowly reversible or irreversible, non-benign condition accompanied by an unpleasant dysphoric affect. Flashback and HPPD appear to be part of a vast and broad spectrum of non-psychopathological and psychopathological states reported by hallucinogen users. Pharmacological agents such as clonidine, perphenazine and clonazepan have been shown to ameliorate this syndrome in some of the individuals seeking treatment.

LSD-induced hallucinogen persisting perception disorder treatment with clonidine: an open pilot study.

Abstract

A pilot open study was conducted in order to evaluate the efficacy of clonidine in the treatment of LSD-induced hallucinogen persisting perception disorder (HPPD). Eight patients fulfilled entrance criteria. All complained of HPPD for at least 3 months and were drug free at least 3 months. They received fixed low doses of clonidine, 0.025 mg, three times a day for 2 months. They were evaluated by the Clinical Global Impression Scale (CGI) and a self-report scale on the severity of symptoms (graded 0-5). Patients scored an average of 5.25 (SD = 0.46) on the CGI and 4 on the self-report scale at baseline, indicating marked psychopathology. One patient dropped out at week 3 and a second patient dropped out at week 5. Of the six patients remaining at the end of 2 months, the average CGI score was 2.5 (SD = 0.55) and the self-report scale score was 2, indicating mild symptomatology. LSD-related flashbacks associated with excessive sympathetic nervous activity may be alleviated with clonidine in some patients.

Do entheogen-induced mystical experiences boost the immune system? Psychedelics, peak experiences, and wellness

Abstract

Daily events that boost the immune system (as indicated by levels of salivary immunoglobulin A), some instances of spontaneous remission, and mystical experiences seem to share a similar cluster of thoughts, feelings, moods, perceptions, and behaviors. Entheogens – psychedelic drugs used in a religious context – can also produce mystical experiences (peak experiences, states of unitive consciousness, intense primary religious experiences) with the same cluster of effects. When this happens, is it also possible that such entheogen-induced mystical experiences strengthen the immune system? Might spontaneous remissions occur more frequently under such conditions? This article advances the so called “Emxis hypothesis” – that entheogen-induced mystical experiences influence the immune system.

The psychopharmacology of hallucinogens.

Abstract

Hallucinogenic drugs have been inhaled, ingested, worshipped, and reviled since prehistory. With the purification and synthesis of bontanical preparations and the ensuing discovery of chemically unique agents, hope was raised regarding their therapeutic potential, but this hope has been clouded by an epidemic of abuse and an inventory of adverse effects. This review examines aspects of that controversy, including the history of hallucinogens, epidemiology of current hallucinogen abuse, the association of LSD use with prolonged psychoses and hallucinogen persisting perception disorder, and the efforts to demonstrate the drug’s therapeutic efficacy. Human subject ramifications in hallucinogen experimentation are discussed. Future lines of research are suggested in human, animal, and tissue culture paradigms.

Placeboing with Psychedelics

Letter to the editor

When we consider the so-called “placebo effect,” we should realize that it is not something mysterious that merely happens on its own. It is something we do with our minds that effects our bodies. To be more accurate: we placebo. To placebo is a verb. Our minds plus our bodies do this, and like any other human activity we can speak of placeboing. When looked at this way, we can ask: How do we placebo? and Can we learn placeboing more skillfully?

A clue comes from studies of stress and emotions in the immune system. It is widely known that negative emotions and stressful life events weaken the immune system, while positive emotions and life events strengthen it. Since positive life events strengthen our immune system, here is a clue to learning to placebo.

A common healing cluster of positive feelings and thoughts accompany many instances of spontaneous remission and spiritual healing. These include feelings of exceedingly positive mood, being cared for in the hands of a loving power, dropping stress, feelings of sacredness, feeling at home in the world, among others. Thoughts include a sense of temporarily transcending one’s identity, forgiving oneself and others, overwhelming gratitude, and increased sense of reality—this is the way things really are and ought to be.

If we can reproduce this cluster, we will be on the way to learning to placebo. Various mindbody techniques including meditation, imagery, contemplative prayer, yoga, the martial arts, breathing techniques, hypnosis, and chanting all suggest a yes answer to this question, and more research to follow these apparent leads may lead to learning how to use these mindbody methods to increase our placeboing skills by strengthening our immune systems.

Do examples of extreme positive emotional states produce extreme healing? The recent flurry of articles about current research into exploring the psychotherapeutic use of psychedelics for post traumatic stress disorder, death anxiety, and other disorders show that these substances are successful when they produce states of unitive consciousness (mystical experiences) and not successful when they do not.

Lost in this discussion is that fact that mystical experiences are the most powerful emotionally positive experiences humans can have, and if normal daily positive events boost the immune system somewhat, do these strongest positive experiences boost it a great deal?

Can this spontaneous cluster of healing thoughts and feelings be recreated in a medical setting? As a 2008 Johns Hopkins study of psilocybin induced mystical experiences showed, under the right conditions and with careful screening, preparation, and professional guidance, psychedelic sessions can produce mystical experiences and a similar cluster of emotions and experiences in normal, healthy, adult volunteers. In a 14-month following up, volunteers’ comments illustrated this healing cluster:

– The utter joy and freedom of letting go—without anxiety—without direction— beyond ego self.
– The understanding that in the eyes of God—all people—were equally important and equally loved by God.
– When I confronted my shadow and yelled “What do you want?” and it disappeared in a puff smoke.

Among the other outcomes were positive mood changes, improved sense of well-being and life satisfaction, positive attitudes about life and/or self, and altruistic social effects. About two-thirds of healthy adults rated as one of the five most important spiritual experiences of their lives, including about one-third who rated them as the single most important spiritual experience of their lives. However, the researchers did not measure possible effects on the immune system.

A question on placeboing: Do overwhelmingly powerful peak experiences stimulated by psychedelics as part of professionally guided sessions boost the immune system? A possible major advance in mindbody health awaits an answer.

LSD-assisted psychotherapy in patients with terminal cancer

Abstract

The paper describes the results of a clinical study exploring the potential of a complex psychotherapeutic program utilizing psychedelic compounds to alleviate the emotional and physical suffering of cancer patients. A total of 60 cancer patients participated in this experimental study. In 44 of these patients, LSD (200-500 ug per os) was administered as an adjunct to psychotherapy; in 19 patients, a new psychedelic compound, dipropyltryptamine (DPT) was administered (60-105 mg i.m.). Three of these patients received both LSD and DPT administered on different sessions.

The therapeutic results were assessed by means of a rating scale reflecting the degree of the patients’ depression, psychological isolation, anxiety, difficulty in management, fear of death, and pain. The ratings were done by attending physicians, nurses, family members, LSD therapists and cotherapists, and independent raters. In addition, the amount of narcotics required in the management of the patient was measured before and after the psychedelic sessions.

Systematic rating was carried out in a group of 31 cancer patients treated by LSD. The comparison of the means of individual ratings from pre- to posttreatment showed significant improvement in all the measured parameters for most of the raters. There was a definite reduction of the narcotic medication; it did not, however, reach the level of statistical significance. The pre- to post-treatment comparison of the global indexes used as gross indicators of the degree of emotional and physical distress, indicated that approximately 29 % of the patients showed dramatic improvement, and another 41.9 % moderate improvement, with 22.6 % essentially unchanged. In 6.4 % of the patients, global indexes showed a decrement in the post therapy ratings.
