Psychedelic medicine: a re-emerging therapeutic paradigm

September 8, 2015 / Ayahuasca, DMT, Humanities & Art, LSD, MDMA, Mushrooms / Psilocybin, Papers, Publications / By / ,

Introduction

In clinical research settings around the world, renewed investigations are taking place on the use of psychedelic substances for treating illnesses such as addiction, depression, anxiety and posttraumatic stress disorder (PTSD). Since the termination of a period of research from the 1950s to the early 1970s, most psychedelic substances have been classified as “drugs of abuse” with no recognized medical value. However, controlled clinical studies have recently been conducted to assess the basic psychopharmacological properties and therapeutic efficacy of these drugs as adjuncts to existing psychotherapeutic approaches. Central to this revival is the re-emergence of a paradigm that acknowledges the importance of set (i.e., psychological expectations), setting (i.e., physical environment) and the therapeutic clinician–patient relationship as critical elements for facilitating healing experiences and realizing positive outcomes [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][…]

Psilocybin, psychological distress, and suicidality

September 1, 2015 / Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

Hendricks et al. (2015) found that having ever used any classic psychedelic substance—namely, dimethyltryptamine (DMT), ayahuasca, lysergic acid diethylamide (LSD), mescaline, peyote or San Pedro, or psilocybin—was associated with a significantly reduced likelihood of past month psychological distress (weighted OR = .81 (.72–.91)), past year suicidal thinking (weighted OR = .86 (.78–.94)), past year suicidal planning (weighted OR = .71 (.54–.94)), and past year suicide attempt (weighted OR = .64 (.46–.89)) in the United States adult population. Although these findings comport with an emerging literature suggesting classic psychedelics may be effective in the treatment of mental health conditions and prevention of self-harm, they do not speak to the potential risk profile or therapeutic applications of psilocybin in particular, which is the most commonly examined classic psychedelic in contemporary clinical research. Considering that psilocybin may be a candidate for future approved medical use in the United States, the United Kingdom, and other nations (Bogenschutz et al., 2015; Grob et al., 2011; Johnson et al., 2014; see also Nutt et al., 2013), an analysis of the specific relationships of psilocybin use with psychological distress and suicidality may help inform decisions by the United States Food and Drug Administration and regulatory bodies of other nations. The objectives of the current research, therefore, were to extend the analysis of Hendricks et al. (2015) by evaluating the associations of lifetime psilocybin use, per se, with past month psychological distress, past year suicidal thinking, past year suicidal planning, and past year suicide attempt in the United States adult population.

Classic hallucinogens in the treatment of addictions

March 14, 2015 / Ayahuasca, DMT, Iboga / Ibogaine, LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications, Substance Use Disorder / By / ,

Abstract

Addictive disorders are very common and have devastating individual and social consequences. Currently available treatment is moderately effective at best. After many years of neglect, there is renewed interest in potential clinical uses for classic hallucinogens in the treatment of addictions and other behavioral health conditions. In this paper we provide a comprehensive review of both historical and recent clinical research on the use of classic hallucinogens in the treatment of addiction, selectively review other relevant research concerning hallucinogens, and suggest directions for future research. Clinical trial data are very limited except for the use of LSD in the treatment of alcoholism, where a meta-analysis of controlled trials has demonstrated a consistent and clinically significant beneficial effect of high-dose LSD. Recent pilot studies of psilocybin-assisted treatment of nicotine and alcohol dependence had strikingly positive outcomes, but controlled trials will be necessary to evaluate the efficacy of these treatments. Although plausible biological mechanisms have been proposed, currently the strongest evidence is for the role of mystical or other meaningful experiences as mediators of therapeutic effects. Classic hallucinogens have an excellent record of safety in the context of clinical research. Given our limited understanding of the clinically relevant effects of classic hallucinogens, there is a wealth of opportunities for research that could contribute important new knowledge and potentially lead to valuable new treatments for addiction.

Psilocybin-Occasioned Mystical Experiences in the Treatment of Tobacco Addiction

February 23, 2015 / Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

Psilocybin-occasioned mystical experiences have been linked to persisting effects in healthy volunteers including positive changes in behavior, attitudes, and values, and increases in the personality domain of openness. In an open-label pilot-study of psilocybin-facilitated smoking addiction treatment, 15 smokers received 2 or 3 doses of psilocybin in the context of cognitive behavioral therapy (CBT) for smoking cessation. Twelve of 15 participants (80%) demonstrated biologically verified smoking abstinence at 6-month follow-up. Participants who were abstinent at 6 months (n=12) were compared to participants still smoking at 6 months (n=3) on measures of subjective effects of psilocybin. Abstainers scored significantly higher on a measure of psilocybin-occasioned mystical experience. No significant differences in general intensity of drug effects were found between groups, suggesting that mystical-type subjective effects, rather than overall intensity of drug effects, were responsible for smoking cessation. Nine of 15 participants (60%) met criteria for “complete” mystical experience. Smoking cessation outcomes were significantly correlated with measures of mystical experience on session days, as well as retrospective ratings of personal meaning and spiritual significance of psilocybin sessions. These results suggest a mediating role of mystical experience in psychedelic-facilitated addiction treatment.

Abstract

Mental health problems are endemic across the globe, and suicide, a strong corollary of poor mental health, is a leading cause of death. Classic psychedelic use may occasion lasting improvements in mental health, but the effects of classic psychedelic use on suicidality are unknown. We evaluated the relationships of classic psychedelic use with psychological distress and suicidality among over 190,000 USA adult respondents pooled from the last five available years of the National Survey on Drug Use and Health (2008–2012) while controlling for a range of covariates. Lifetime classic psychedelic use was associated with a significantly reduced odds of past month psychological distress (weighted odds ratio (OR)=0.81 (0.72–0.91)), past year suicidal thinking (weighted OR=0.86 (0.78–0.94)), past year suicidal planning (weighted OR=0.71 (0.54–0.94)), and past year suicide attempt (weighted OR=0.64 (0.46–0.89)), whereas lifetime illicit use of other drugs was largely associated with an increased likelihood of these outcomes. These findings indicate that classic psychedelics may hold promise in the prevention of suicide, supporting the view that classic psychedelics’ most highly restricted legal status should be reconsidered to facilitate scientific study, and suggesting that more extensive clinical research with classic psychedelics is warranted.

Can psychedelic compounds play a part in drug dependence therapy?

January 5, 2015 / Ayahuasca, Iboga / Ibogaine, Ketamine, LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / ,

Abstract

After a 40-year hiatus there is now a revisiting of psychedelic drug therapy throughout psychiatry, with studies examining the drugs psilocybin, ketamine, ibogaine and ayahuasca in the treatment of drug dependence. Limitations to these therapies are both clinical and legal, but the possibility of improving outcomes for patients with substance dependency imposes an obligation to research this area.

Psychedelic-facilitated smoking cessation: An online survey

January 1, 2015 / LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

Abstract

Aims:
Pilot laboratory results suggest psilocybin may be an efficacious adjunct to smoking cessation treatment. However, no study has examined smoking cessation after psychedelic use in naturalistic settings.
Methods:
We are conducting an online survey collecting demographics, smoking history, and other data from people who self-report quitting/reducing smoking after taking a psychedelic.
Results:
Among current completers (N=164), LSD (49%) and psilocybin (32%) were the drugs most commonly associated with quitting/reducing, with a mode of 2-5 lifetime uses each. Participants reported smoking a mean of 12 cigs/day for a mean of 8 yrs before the experience. 62(38%) reported total and continuing abstinence after their experience, with 29 of the 62 (47%) reporting >1yr abstinence, and 7 (11%) reporting >10 yrs abstinence. Another 67 of the 164 (41%) reported persisting smoking reduction, from a mode of 10-20 cigs/day before, to a mode of <1 cig/month after the experience. The remaining 35 (21%) reported temporary reduction, with 6 of the 35 (17%) reporting >1 yr reduction. Although the majority of withdrawal symptoms were rated as equal in severity to previous quit attempts, depression, irritability, anxiety, and craving were rated as “much less severe.” 141 of the 164 (86%) reported no premeditated intention to quit/reduce smoking, and 159 (97%) described their experience as highly meaningful, with
97 (59%) considering it among the 10 most meaningful experiences of their lives. Participants cited changed life priorities/values (26%), strengthened belief in their ability to quit (26%), and changed future orientation (17%) as the most important effects leading to quitting/reducing. Other changes reported after psychedelic use included reduced alcohol (38%) and other drug use (23%).
Conclusions:
Psychedelics may prompt temporary or prolonged smoking cessation, suggesting that careful administration in a treatment context may enhance motivation in changing addictive behaviors. Psychological and neurobiological mechanisms underlying such behavioral changes require further investigation.

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

September 11, 2014 / Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , , ,

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

July 1, 2014 / Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

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.
