IJTS Special Topic Section: Ketamine ● Ethnographic Accounts of Ketamine Explorations in Psychedelic Culture

January 1, 2014 / Humanities & Art, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

Abstract

Off-label use of ketamine as a mind-altering substance did not begin in the laboratory, but in the psychedelic culture that grew out of the 1960s counterculture movement. Whatever the risks and limitations of such experimentation, without them the remarkable therapeutic effects of the drug might well have gone unnoticed, and unresearched. The following personal accounts—both inspiring and cautionary—offer glimpses into the cultural contexts that found ketamine to be much more than a reliable anesthetic.

January 1, 2014 / Humanities & Art, LSD, MDMA, Papers, Psychiatry & Medicine, Psychology, Publications, Substance Use Disorder / By /

Abstract

Richard Yensen was a research fellow at the Maryland Psychiatric Research Center from 1972 to 1976. He studied psychedelic psychotherapy with Stanislav Grof, M.D. and other senior staff. During this time he treated patients with substance abuse disorders, cancer, neurosis, and other health professionals seeking a training experience. Dr. Yensen did his Ph.D. dissertation on the use of MDA in psychotherapy with neurotic outpatients and conducted his research at the MPRC. Through many years of experience in governmentsanctioned psychedelic research, he has evolved a non-drug shamanistic psychotherapy called Perceptual Affective Therapy. In the 1990’s Richard was co-holder of IND 3250, an investigational new drug permit issued by the U.S. Food and Drug Administration to study LSD and psychotherapy until 2006. He is currently a licensed psychologist in California and director of the Orenda Institute in Vancouver and Cortes Island, British Columbia, Canada and president of the Salvador Roquet Psychosynthesis Association. He has served on the faculties of Harvard Medical School, Johns Hopkins University and the University of Maryland Medical School in Baltimore.

Psilocybin – Summary of knowledge and new perspectives

December 17, 2013 / Anxiety Disorders / PTSD, Depressive Disorders, Headache Pain and Neurological Disorders, Mushrooms / Psilocybin, Neuroscience, Papers, Pharmacology & Chemistry, Psychology, Psychotic Disorders, Publications, Substance Use Disorder / By / , ,

Abstract

Psilocybin, a psychoactive alkaloid contained in hallucinogenic mushrooms, is nowadays given a lot of attention in the scientific community as a research tool for modeling psychosis as well as due to its potential therapeutic effects. However, it is also a very popular and frequently abused natural hallucinogen. This review summarizes all the past and recent knowledge on psilocybin. It briefly deals with its history, discusses the pharmacokinetics and pharmacodynamics, and compares its action in humans and animals. It attempts to describe the mechanism of psychedelic effects and objectify its action using modern imaging and psychometric methods. Finally, it describes its therapeutic and abuse potential.

Ibogaine: a review

December 4, 2013 / Anthropology & Sociology, Biology & Ethnobotany, Iboga / Ibogaine, Papers, Pharmacology & Chemistry, Psychology, Publications, Substance Use Disorder / By /

Publisher Summary

The chapter discusses ibogaine, which is a naturally occurring plant alkaloid with a history of use as a medicinal and ceremonial agent in West Central Africa and has been alleged to be effective in the treatment of drug abuse. The National Institute on Drug Abuse (NIDA) has given significant support to animal research, and the U.S. Food and Drug Administration (FDA) has approved Phase I studies in humans. The chapter discusses the first International Conference on Ibogaine. A major focus of the Conference was the possible mechanism(s) of action of ibogaine. Another important focus of the Conference was to discuss human experience with ibogaine and preclinical and clinical evidence of efficacy and safety. The Conference also featured presentations related to the sociological and anthropological aspects of the sacramental context of the use of iboga in Africa and the distinctive ibogaine subculture of the U.S and Europe. Ibogaine is the most abundant alkaloid in the root bark of the Apocynaceous shrub Tabernanthe iboga, which grows in West Central Africa. The chapter presents a timeline that outlines the historical events relating to the development of ibogaine as a treatment for drug dependence. Ibogaine and serotonin both contain an indole ring in their structure, and ibogaine has been shown to bind to the serotonin transporter and to increase serotonin levels in the nucleus accumbens (NAc). Stereotypy is a methodologic issue that might explain some of the disparate results regarding ibogaine’s interaction with the locomotor response to cocaine.

Dimethyltryptamine (DMT): Prevalence, user characteristics and abuse liability in a large global sample

November 27, 2013 / DMT, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

Abstract

This paper presents original research on prevalence, user characteristics and effect profile of N,N-dimethyltryptamine (DMT), a potent hallucinogenic which acts primarily through the serotonergic system. Data were obtained from the Global Drug Survey (an anonymous online survey of people, many of whom have used drugs) conducted between November and December 2012 with 22,289 responses. Lifetime prevalence of DMT use was 8.9% (n=1980) and past year prevalence use was 5.0% (n=1123). We explored the effect profile of DMT in 472 participants who identified DMT as the last new drug they had tried for the first time and compared it with ratings provided by other respondents on psilocybin (magic mushrooms), LSD and ketamine. DMT was most often smoked and offered a strong, intense, short-lived psychedelic high with relatively few negative effects or “come down”. It had a larger proportion of new users compared with the other substances (24%), suggesting its popularity may increase. Overall, DMT seems to have a very desirable effect profile indicating a high abuse liability that maybe offset by a low urge to use more.

Effective interventions in the problematic use of alcohol and other drugs

October 1, 2013 / LSD, Papers, Psychology, Publications, Substance Use Disorder / By / , , , ,

Abstract

OBJECTIVE:
Synthesize and assess the available scientific evidence from the period 2008-2012 on interventions of demonstrated efficacy in the treatment and rehabilitation of adolescents and adults engaged in the problematic use of alcohol and other substances.

METHODS:
A systematic review was undertaken with search and analysis of national and international literature on the subject in Spanish and English in the main international databases: PubMed/MEDLINE, LILACS, Embase, PsycINFO, SciELO, the databases of the York University Centre for Reviews and Dissemination (DARE, ETS Database), the Cochrane Library, and other sources of gray literature. The search criteria included randomized clinical trials and systematic reviews but excluded observational studies, qualitative studies, and articles of poor methodological quality.

RESULTS:
The final sample consisted of 69 studies. The psychosocial interventions shown to be effective were cognitive behavioral therapy, family interventions, self-help interventions using the Internet, couples behavioral therapy, community strengthening and family training, telephone monitoring and support, and integrated therapy for substance abuse disorder with anxiety and depression comorbidity. Pharmacological interventions of demonstrated effectiveness were acamprosate, lysergic acid diethylamide (LSD), and benzodiazepines in problematic alcohol use, as well as maintenance therapy with high-dose opioids.

CONCLUSIONS:
The demonstrated effectiveness of psychosocial and pharmacological interventions is slight but significant. However, strongly multidisciplinary interventions that use a cognitive behavioral approach and the involvement of people close to the consumer, as well as some of the specific pharmacological interventions, have been shown to yield the best results in terms of indicators of abstinence and prevention of relapses.

Survey: Quit smoking after a psychedelic experience?

December 6, 2021 / Publications, Substance Use Disorder / By

Researchers from the Johns Hopkins University School of Medicine are currently recruiting individuals who have quit smoking cigarettes or reduced their smoking (even temporarily) after an experience with a psychedelic, for participation in an online survey. Their team has previously conducted innovative research on the effects of compounds including psilocybin, dextromethorphan, and salvinorin A.

The goal of this survey is to learn more about whether psychedelic drugs are associated with reduction or cessation of cigarette smoking. The researchers want to characterize people’s experiences in non-­laboratory settings in which taking a psychedelic may have led to reducing or quitting smoking. For the purposes of this survey, the survey will be asking specifically about individuals who have quit smoking cigarettes or reduced their smoking (even temporarily) after experiences with psilocybin (magic) mushrooms, LSD, morning glory seeds, mescaline, peyote cactus, San Pedro cactus, DMT, or ayahuasca. This research study has been approved by the Institutional Review Board of Johns Hopkins Medicine.

The survey is completely anonymous (IP addresses will not be recorded) and will require 40-45 minutes to complete. If you are interested in participating, please click this link. Participation is voluntary and will not be financially compensated.

Participants must be 18+ years of age, speak/write English fluently, and have experienced a reduction or cessation of cigarette smoking after an experience with one of the psychedelic substances listed above. For more information, please contact the researchers via the site’s private messaging system.

Principal Investigator of this study, Matthew W. Johnson was a speaker at our Interdisciplinary Conference on Psychedelic Research in 2012. A video on the topic of this study can be watched below.

A proposal to evaluate mechanistic efficacy of hallucinogens in addiction treatment

September 1, 2013 / Ayahuasca, DMT, Iboga / Ibogaine, LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / ,

Abstract

Current treatments for addiction are frequently ineffective. Hallucinogenic therapy has been indicated as helpful for a range of substance use disorders, yet this approach remains understudied and publicly unavailable. It is nonetheless a promising treatment, which has significant, long-term beneficial effects with single doses and a profile characterized by general safety, low toxicity, and non-addictiveness. However, pharmacological interventions, such as hallucinogens, should not be offered if the same effects (e.g. psychological insights/mystical experiences) and outcomes (e.g. decreased drug use) could be achieved absent pharmacological intervention. To date, there have been no clinical comparisons of drug-induced altered states with non-drug-induced states for addiction treatment. We propose and then outline a clinical trial to address this gap in knowledge. The proposed design would evaluate abstinence outcomes in a population of prescription opioid abusers after exposure to one of three conditions: a drug-induced altered state using psilocybin, a non-drug-induced altered state via hyperventilation (Holotropic Breathwork), and an active placebo with niacin. The outcomes of such a study would reveal important differences in therapeutic potential by discriminating hallucinogen-dependent effects from those psychological effects resulting from altered states.

Methoxetamine (MXE) – A Phenomenological Study of Experiences Induced by a “Legal High” from the Internet

August 2, 2013 / Papers, Publications, Substance Use Disorder / By / ,

Abstract

Methoxetamine (MXE), a ketamine analogue, is one of the new “legal highs” sold on the Internet. The aim of this qualitative study was to provide an initial understanding of what characterizes the experiences induced by MXE. Anonymously written reports (33 persons) on the effects of MXE were collected from public Internet forums and analyzed using the Empirical Phenomenological Psychological Method. The analysis generated 10 themes: (1) preparation, motivation and anticipation; (2) initial effects; (3) malfunction of cognitive processes stabilizing normal state; (4) inner personal processes and learning; (5) emotional processes; (6) altered sensory perception; (7) dissolution and transition; (8) spiritual and transcendental experiences; (9) effects and processes after the experience; (10) re-dosing and addiction.

MXE induced a heavily altered state of consciousness. The effects were similar to those induced by classic hallucinogens (such as LSD, psilocybin) and the dissociative ketamine. MXE seemed to have quite a high abuse potential. Beside the positive effects described, negative effects like fear and anxiety were also reported. Acceptance was considered the best coping strategy. Dissolution of identity and body often culminated in spiritual and transcendental experiences. More research is needed on safety issues, how to minimize harm, and the motivation for using legal highs.

Studying the Effects of Classic Hallucinogens in the Treatment of Alcoholism: Rationale, Methodology, and Current Research with Psilocybin

March 1, 2013 / LSD, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications, Substance Use Disorder / By /

Abstract

Recent developments in the study of classic hallucinogens, combined with a re-appraisal of the older literature, have led to a renewal of interest in possible therapeutic applications for these drugs, notably their application in the treatment of addictions. This article will first provide a brief review of the research literature providing direct and indirect support for the possible therapeutic effects of classic hallucinogens such as psilocybin and lysergic acid diethylamide (LSD) in the treatment of addictions. Having provided a rationale for clinical investigation in this area, we discuss design issues in clinical trials using classic hallucinogens, some of which are unique to this class of drug. We then discuss the current status of this field of research and design considerations in future randomized trials.
