Why Psychiatry Needs Psychedelics and Psychedelics Need Psychiatry

March 11, 2014 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By /

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.

MDMA and the “Ecstasy Paradigm”

March 11, 2014 / MDMA, Neuroscience, Papers, Psychology, Publications / By /

Abstract

For nearly 30 years, there has been a steady flow of research papers highlighting the dangers of MDMA and the implications for ecstasy users. After such a long time, it would be reasonable to expect that these dangers would be obvious due to the large number of ecstasy users. The available evidence does not indicate that there are millions of ecstasy users experiencing any problems linked to their ecstasy use. The “precautionary principle” suggests that, in the absence of knowing for certain, “experts” should argue that MDMA be avoided. However, this may have been taken too far, as the dire warnings do not seem to be reducing with the lack of epidemiological evidence of clinically relevant problems. The “ecstasy paradigm” is one way of articulating this situation, in that the needs of research funders and publication bias lead to a specific set of subcultural norms around what information is acceptable in the public domain. By digging a little deeper, it is easy to find problems with the evidence base that informs the public debate around MDMA. The key question is whether it is acceptable to maintain this status quo given the therapeutic potential of MDMA.

The Potential Dangers of Using MDMA for Psychotherapy

March 11, 2014 / Anxiety Disorders / PTSD, MDMA, Neuroscience, Papers, Psychology, Publications / By /

Abstract

MDMA has properties that may make it attractive for psychotherapy, although many of its effects are potentially problematic. These contrasting effects will be critically reviewed in order to assess whether MDMA could be safe for clinical usage. Early studies from the 1980s noted that MDMA was an entactogen, engendering feelings of love and warmth. However, negative experiences can also occur with MDMA since it is not selective in the thoughts or emotions it releases. This unpredictability in the psychological material released is similar to another serotonergic drug, LSD. Acute MDMA has powerful neurohormonal effects, increasing cortisol, oxytocin, testosterone, and other hormone levels. The release of oxytocin may facilitate psychotherapy, whereas cortisol may increase stress and be counterproductive. MDMA administration is followed by a period of neurochemical recovery, when low serotonin levels are often accompanied by lethargy and depression. Regular usage can also lead to serotonergic neurotoxicity, memory problems, and other psychobiological problems. Proponents of MDMA-assisted therapy state that it should only be used for reactive disorders (such as PTSD) since it can exacerbate distress in those with a prior psychiatric history. Overall, many issues need to be considered when debating the relative benefits and dangers of using MDMA for psychotherapy.

Self-Experimentations with Psychedelics Among Mental Health Professionals: LSD in the Former Czechoslovakia

March 11, 2014 / LSD, Papers, Psychology, Publications / By / ,

Abstract

This article enquires into auto-experiments with psychedelics. It is focused on the experiences and current attitudes of mental health professionals who experimented with LSD in the era of legal research of this substance in the former Czechoslovakia. The objective of the follow-up study presented was to assess respondents’ long-term views on their LSD experience(s). A secondary objective was to capture the attitude of the respondents toward the use of psychedelics within the mental health field. A total of 22 individuals participated in structured interviews. None of the respondents reported any long-term negative effect and all of them except two recorded enrichment in the sphere of self-awareness and/or understanding to those with mental disorder(s). Although there were controversies with regard to the ability of preventing possible negative consequences, respondents were supportive towards self-experiments with LSD in mental health sciences. This article is the first systematic examination of the self-experimentation with psychedelics that took place east of the Iron Curtain.

From Hofmann to the Haight Ashbury, and into the Future: The Past and Potential of Lysergic Acid Diethlyamide

March 11, 2014 / LSD, Papers, Psychology, Publications / By / , ,

Abstract

Since the discovery of its psychedelic properties in 1943, lysergic acid diethylamide (LSD) has been explored by psychiatric/therapeutic researchers, military/intelligence agencies, and a significant portion of the general population. Promising early research was halted by LSD’s placement as a Schedule I drug in the early 1970s. The U.S. Army and CIA dropped their research after finding it unreliable for their purposes. NSDUH estimates that more than 22 million (9.1% of the population) have used LSD at least once in their lives. Recently, researchers have been investigating the therapeutic use of LSD and other psychedelics for end-of-life anxiety, post-traumatic stress disorder (PTSD), cancer, and addiction treatment. Adverse psychedelic reactions can be managed using talkdown techniques developed and in use since the 1960s.

Safety and Efficacy of Lysergic Acid Diethylamide-Assisted Psychotherapy for Anxiety Associated With Life-threatening Diseases

March 3, 2014 / Anxiety Disorders / PTSD, LSD, Papers, Psychology, Publications / By / , , , , , ,

Abstract

A double-blind, randomized, active placebo-controlled pilot study was conducted to examine safety and efficacy of lysergic acid diethylamide (LSD)-assisted psychotherapy in 12 patients with anxiety associated with life-threatening diseases. Treatment included drug-free psychotherapy sessions supplemented by two LSD-assisted psychotherapy sessions 2 to 3 weeks apart. The participants received either 200 mcg of LSD (n=8) or 20 mcg of LSD with an open-label crossover to 200 mcg of LSD after the initial blinded treatment was unmasked (n=4). At the 2-month follow-up, positive trends were found via the State-Trait Anxiety Inventory (STAI) in reductions in trait anxiety (p=0.033) with an effect size of 1.1, and state anxiety was significantly reduced (p= 0.021) with an effect size of 1.2, with no acute or chronic adverse effects persisting beyond 1 day after treatment or treatment-related serious adverse events. STAI reductions were sustained for 12 months. These results indicate that when administered safely in a methodologically rigorous medically supervised psychotherapeutic setting, LSD can reduce anxiety, suggesting that larger controlled studies are warranted.

Indigenous healing practice: ayahuasca. Opening a discussion

March 1, 2014 / Ayahuasca, Papers, Psychology, Publications, Substance Use Disorder / By / ,

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?

February 18, 2014 / Ketamine, Neuroscience, Papers, Psychiatry & Medicine, Psychology, Publications, Substance Use Disorder / By / , , , , ,

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.

Do the dissociative side effects of ketamine mediate its antidepressant effects?

February 18, 2014 / Depressive Disorders, Ketamine, Neuroscience, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , , , , ,

Abstract

Background

The N-methyl-d-aspartate receptor antagonist ketamine has rapid antidepressant effects in major depression. Psychotomimetic symptoms, dissociation and hemodynamic changes are known side effects of ketamine, but it is unclear if these side effects relate to its antidepressant efficacy.

Methods

Data from 108 treatment-resistant inpatients meeting criteria for major depressive disorder and bipolar disorder who received a single subanesthetic ketamine infusion were analyzed. Pearson correlations were performed to examine potential associations between rapid changes in dissociation and psychotomimesis with the Clinician-Administered Dissociative States Scale (CADSS) and Brief Psychiatric Rating Scale (BPRS), respectively, manic symptoms with Young Mania Rating Scale (YMRS), and vital sign changes, with percent change in the 17-item Hamilton Depression Rating scale (HDRS) at 40 and 230 min and Days 1 and 7.

Results

Pearson correlations showed significant association between increased CADSS score at 40 min and percent improvement with ketamine in HDRS at 230 min (r=−0.35, p=0.007) and Day 7 (r=−0.41, p=0.01). Changes in YMRS or BPRS Positive Symptom score at 40 min were not significantly correlated with percent HDRS improvement at any time point with ketamine. Changes in systolic blood pressure, diastolic blood pressure, and pulse were also not significantly related to HDRS change.

Limitations

Secondary data analysis, combined diagnostic groups, potential unblinding.

Conclusions

Among the examined mediators of ketamine׳s antidepressant response, only dissociative side effects predicted a more robust and sustained antidepressant. Prospective, mechanistic investigations are critically needed to understand why intra-infusion dissociation correlates with a more robust antidepressant efficacy of ketamine.

MDMA decreases the effects of simulated social rejection

February 8, 2014 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / , , ,

Abstract

3-4-Methylenedioxymethamphetamine (MDMA) increases self-reported positive social feelings and decreases the ability to detect social threat in faces, but its effects on experiences of social acceptance and rejection have not been determined. We examined how an acute dose of MDMA affects subjective and autonomic responses to simulated social acceptance and rejection. We predicted that MDMA would decrease subjective responses to rejection. On an exploratory basis, we also examined the effect of MDMA on respiratory sinus arrhythmia (RSA), a measure of parasympathetic cardiac control often thought to index social engagement and emotional regulation. Over three sessions, healthy adult volunteers with previous MDMA experience (N = 36) received capsules containing placebo, 0.75 or 1.5 mg/kg of MDMA under counter-balanced double-blind conditions. During expected peak drug effect, participants played two rounds of a virtual social simulation task called “Cyberball” during which they experienced acceptance in one round and rejection in the other. During the task we also obtained electrocardiograms (ECGs), from which we calculated RSA. After each round, participants answered questionnaires about their mood and self-esteem. As predicted, MDMA decreased the effect of simulated social rejection on self-reported mood and self-esteem and decreased perceived intensity of rejection, measured as the percent of ball tosses participants reported receiving. Consistent with its sympathomimetic properties, MDMA decreased RSA as compared to placebo. Our finding that MDMA decreases perceptions of rejection in simulated social situations extends previous results indicating that MDMA reduces perception of social threat in faces. Together these findings suggest a cognitive mechanism by which MDMA might produce pro-social behavior and feelings and how the drug might function as an adjunct to psychotherapy. These phenomena merit further study in non-simulated social environments.
