Pilot study of the 5-HT2AR agonist psilocybin in the treatment of tobacco addiction

Abstract

Despite suggestive early findings on the therapeutic use of hallucinogens in the treatment of substance use disorders, rigorous follow-up has not been conducted. To determine the safety and feasibility of psilocybin as an adjunct to tobacco smoking cessation treatment we conducted an open-label pilot study administering moderate (20 mg/70 kg) and high (30 mg/70 kg) doses of psilocybin within a structured 15-week smoking cessation treatment protocol. Participants were 15 psychiatrically healthy nicotine-dependent smokers (10 males; mean age of 51 years), with a mean of six previous lifetime quit attempts, and smoking a mean of 19 cigarettes per day for a mean of 31 years at intake. Biomarkers assessing smoking status, and self-report measures of smoking behavior demonstrated that 12 of 15 participants (80%) showed seven-day point prevalence abstinence at 6-month follow-up. The observed smoking cessation rate substantially exceeds rates commonly reported for other behavioral and/or pharmacological therapies (typically <35%). Although the open-label design does not allow for definitive conclusions regarding the efficacy of psilocybin, these findings suggest psilocybin may be a potentially efficacious adjunct to current smoking cessation treatment models. The present study illustrates a framework for future research on the efficacy and mechanisms of hallucinogen-facilitated treatment of addiction.

Examining the psychological mechanisms of psilocybin-assisted smoking cessation treatment: A pilot study

Abstract

Anthropological evidence and early experimental studies suggest that structured administration of 5-HT2A agonist hallucinogens (e.g., LSD, psilocybin) may have potential in treating addictions, including alcoholism and opioid dependence. Psilocybin administration has been recently linked to persisting effects including personality change (i.e., increased NEO Openness), mood enhancement, and behavior change. The association between mood, personality, and addiction has been well documented, and suggests that psilocybin may be useful in the treatment of addiction.

Therapeutic Effects of Ritual Ayahuasca Use in the Treatment of Substance Dependence—Qualitative Results

Abstract

This qualitative empirical study explores the ritual use of ayahuasca in the treatment of addictions. Ayahuasca is an Amazonian psychedelic plant compound created from an admixture of the vine Banisteriopsis caapi and the bush Psychotria viridis. The study included interviews with 13 therapists who apply ayahuasca professionally in the treatment of addictions (four indigenous healers and nine Western mental health professionals with university degrees), two expert researchers, and 14 individuals who had undergone ayahuasca-assisted therapy for addictions in diverse contexts in South America. The study provides empirically based hypotheses on therapeutic mechanisms of ayahuasca in substance dependence treatment. Findings indicate that ayahuasca can serve as a valuable therapeutic tool that, in carefully structured settings, can catalyze neurobiological and psychological processes that support recovery from substance dependencies and the prevention of relapse. Treatment outcomes, however, can be influenced by a number of variables that are explained in this study. In addition, issues related to ritual transfer and strategies for minimizing undesired side-effects are discussed.

Why Psychiatry Needs Psychedelics and Psychedelics Need Psychiatry

Abstract

Without researching psychedelic drugs for medical therapy, psychiatry is turning its back on a group of compounds that could have great potential. Without the validation of the medical profession, the psychedelic drugs, and those who take them off-license, remain archaic sentiments of the past, with the users maligned as recreational drug abusers and subject to continued negative opinion. These two disparate groups—psychiatrists and recreational psychedelic drug users—are united by their shared recognition of the healing potential of these compounds. A resolution of this conflict is essential for the future of psychiatric medicine and psychedelic culture alike. Progression will come from professionals working in the field adapting to fit a conservative paradigm. In this way, they can provide the public with important treatments and also raise the profile of expanded consciousness in mainstream society.

The Heffter Research Institute: Past and Hopeful Future

Abstract

This essay describes the founding of the Heffter Research Institute in 1993 and its development up to the present. The Institute is the only scientific research organization dedicated to scientific research into the medical value of psychedelics, and it has particularly focused on the use of psilocybin. The first clinical treatment study was of the value of psilocybin in obsessive-compulsive disorder. Next was a UCLA study of psilocybin to treat end-of-life distress in end-stage cancer patients. While that study was ongoing, a trial was started at Johns Hopkins University (JHU) to study the efficacy of psilocybin in treating anxiety and depression resulting from a cancer diagnosis. Following the successful completion of the UCLA project, a larger study was started at New York University, which is near completion. A pilot study of the value of psilocybin in treating alcoholism at the University of New Mexico also is nearing completion, with a larger two-site study being planned. Other studies underway involve the use of psilocybin in a smoking cessation program and a study of the effects of psilocybin in long-term meditators, both at JHU. The institute is now planning for a Phase 3 clinical trial of psilocybin to treat distress in end-stage cancer patients.

Indigenous healing practice: ayahuasca. Opening a discussion

Abstract

This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

Therapeutic infusions of ketamine: Do the psychoactive effects matter?

Abstract

Background

Sub-anesthetic ketamine infusions may benefit a variety of psychiatric disorders, including addiction. Though ketamine engenders transient alterations in consciousness, it is not known whether these alterations influence efficacy. This analysis evaluates the mystical-type effects of ketamine, which may have therapeutic potential according to prior research, and assesses whether these effects mediate improvements in dependence-related deficits, 24 h postinfusion.

Methods

Eight cocaine dependent individuals completed this double-blind, randomized, inpatient study. Three counter-balanced infusions separated by 48 h were received: lorazepam (2 mg) and two doses of ketamine (0.41 mg/kg and 0.71 mg/kg, with the former dose always preceding the latter). Infusions were followed within 15 min by measures of dissociation (Clinician Administered Dissociative Symptoms Scale: CADSS) and mystical-type effects (adapted from Hood’s Mysticism Scale: HMS). At baseline and 24 h postinfusion, participants underwent assessments of motivation to stop cocaine (University of Rhode Island Change Assessment) and cue-induced craving (by visual analogue scale for cocaine craving during cue exposure).

Results

Ketamine led to significantly greater acute mystical-type effects (by HMS) relative to the active control lorazepam; ketamine 0.71 mg/kg was associated with significantly higher HMS scores than was the 0.41 mg/kg dose. HMS score, but not CADSS score, was found to mediate the effect of ketamine on motivation to quit cocaine 24 h postinfusion.

Conclusions

These findings suggest that psychological mechanisms may be involved in some of the anti-addiction benefits resulting from ketamine. Future research can evaluate whether the psychoactive effects of ketamine influence improvements in larger samples.

Hallucinogen use predicts reduced recidivism among substance-involved offenders under community corrections supervision

Abstract

Hallucinogen-based interventions may benefit substance use populations, but contemporary data informing the impact of hallucinogens on addictive behavior are scarce. Given that many individuals in the criminal justice system engage in problematic patterns of substance use, hallucinogen treatments also may benefit criminal justice populations. However, the relationship between hallucinogen use and criminal recidivism is unknown. In this longitudinal study, we examined the relationship between naturalistic hallucinogen use and recidivism among individuals under community corrections supervision with a history of substance involvement (n=25,622). We found that hallucinogen use predicted a reduced likelihood of supervision failure (e.g. noncompliance with legal requirements including alcohol and other drug use) while controlling for an array of potential confounding factors (odds ratio (OR)=0.60 (0.46, 0.79)). Our results suggest that hallucinogens may promote alcohol and other drug abstinence and prosocial behavior in a population with high rates of recidivism.

Peyote as Medicin: an Examination of Therapeutic Factors that Contribute to Healing

Abstract

The therapeutic value of particular “hallucinogenic” plants is recognized by various cultures throughout the globe, with evidence suggesting that the medical and ritual use of these plants may date back several millennia in some instances. Peyote, a psychoactive cactus, is considered a medicine by many Native Americans, and has been hailed as a cure for alcoholism despite having no “scientifically” accepted medical use. The notion that hallucinogenic compounds may have therapeutic applications, however, is increasingly supported by scientific research. Despite the heavy focus of allopathic medicine on pharmacology, the therapeutic value of peyote must be understood in holistic terms. By uniting Gordon Claridge’s work on the Total Drug Effect with the work of Daniel E. Moerman and Wayne B. Jonas on the Meaning Response, and with Toksoz Karasu’s Agents of Therapeutic Change, a therapeutic model emerges that can explain how the symbolic, ritual, and community components of the peyote ceremony combine with peyote’s distinctive pharmacological properties to produce a unique and efficacious healing experience.

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

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.
