Prosocial effects of MDMA: A measure of generosity

March 3, 2015 / MDMA, Papers, Psychology, Publications / By / , , ,

Abstract

Background: 3,4-methylenedioxymethamphetamine (MDMA) produces “prosocial” effects that contribute to its recreational use. Few studies have examined the cognitive and behavioral mechanisms by which MDMA produces these effects. Here we examined the effect of MDMA on a specific prosocial effect, i.e. generosity, using a task in which participants make decisions about whether they or another person will receive money (Welfare Trade-Off Task; WTT).

Methods: The project included one study without drug administration and one with MDMA. In Study 1, we administered the WTT to healthy adults (N = 361) and examined their performance in relation to measures of personality and socioeconomic status. In Study 2, healthy volunteers with MDMA experience (N = 32) completed the WTT after MDMA administration (0, 0.5, or 1.0 mg/kg).

Results: As expected, in both studies participants were more generous with a close friend than an acquaintance or stranger. In Study 1, WTT generosity was related to household income and trait Agreeableness. In Study 2, MDMA (1.0 mg/kg) increased generosity toward a friend but not a stranger, whereas MDMA (0.5 mg/kg) slightly increased generosity toward a stranger, especially among female participants.

Conclusions: These data indicate that the WTT is a valuable, novel tool to assess a component of prosocial behavior, i.e. generosity to others. The findings support growing evidence that MDMA produces prosocial effects, but, as with oxytocin, these appear to depend on the social proximity of the relationships. The brain mechanisms underlying the construct of generosity, or the effects of MDMA on this measure, remain to be determined.

Abstract

Health-related psychedelic research should focus on helping us flourish, not just remedying ill-health or addiction. We don’t know enough about how psychedelics could enhance human flourishing. Factors promoting health-through-flourishing include finding meaning in life, spiritual practices, comfortable levels of social bonds, emotionally/physically satisfying sex in a long-term monogamous relationship and control over one’s daily life. Psychedelic research could find more.Neuroscience anchors psychedelic research into disease and disorder, e.g. addiction, PSTD, migraine, anxiety, pain etc. Neurophenomenological psychedelics research could illuminate relationships between health, ASC/NOSCs and cognitive liberty to promote human flourishing. If we accept the self as an epiphenomenon of subsystems within the brain, we ‘know’ ‘unconsciously’, but are not aware of, many things which affect our lives profoundly. These include control over identifying, remembering and forgetting our states of mind and how to move between them. A prerequisite for integrated investigations into ASC/NOSCs is the establishment of a taxonomic knowledge base which lists, categorises and characterises ASC/NOSCs to enable us to choose specific states of mind and move securely among them. Or, in other words, to enable us to exercise our cognitive liberty safely.

I believe that human health and flourishing would be enhanced were we able to direct our states of being by consciously choosing them. Given the promise of mindfulness techniques to enhance our health, happiness and spiritual growth, constructing both personal and generic classifications of salient ASC/NOSCs makes sense. Laws need to change. The neuroscience of pleasure, love, spirituality, decision-making, pattern recognition and location of meaning should inform health-enhancing psychedelic research while promoting flourishing through cognitive liberty.

As part of cognitive liberty, our end-of-life choices should include how we die. In other words, our idea of the good death should include access to psychedelics. Dying high is increasingly likely to become a popular choice as baby boomers age and place their economic clout behind the reform of end-of-life laws as well as drug laws. Achieving such crucial legal changes depends partly on the ability to produce research to anchor evidence based law and policy. Research into psychedelics, ASC/NOSCs and the neurobiology of the dying process is essential.

Introduction to ‘Beneficial Effects of Psychedelics with a Special Focus on Addictions’

We are witnessing a revival of psychedelic research. An increasing number of studies investigating the therapeutic use of psychedelics are currently underway at some of the most renowned universities. Dedicating a second issue of ‘Current Drug Abuse Reviews’ to psychedelics aims to keep up with this blossoming field. With the availability of modern scientific instruments, psychedelic research is once again gaining a firm foothold in academia.

The idea of this special issue originated at the Interdisciplinary Conference on Psychedelic Research, organised by the OPEN Foundation in 2012. OPEN was founded in 2007 in the Netherlands, in order to stimulate and advance scientific research into psychedelics. This special issue of CDAR takes an interdisciplinary approach to the topic of psychedelics and mental health, while maintaining a particular focus on applications of psychedelics in the fields of substance abuse and addiction. This special issue also takes a critical look at some widespread assumptions about psychedelics, introduces new ideas and suggests novel directions for future research.

Abstract

Kosmicare project implements crisis intervention in situations related to the use of psychoactive substances at Boom Festival (Portugal). We present evaluation research that aims to contribute to the transformation of the project into an evidence-based intervention model. It relies on harm reduction and risk minimization principles, crisis intervention models, and Grof’s psychedelic psychotherapy approach for crisis intervention in situations related to unsupervised use of psychedelics. Intervention was expected to produce knowledge about the relation between substance use and mental health impact in reducing potential risk related to the use of psychoactive substances and mental illness, as well as an impact upon target population’s views of themselves, their relationship to substance use, and to life events in general. Research includes data on process and outcome indicators through a mixed methods approach, collected next to a sample of n=176 participants. Sample size varied considerably, however, among different research measures. 52% of Kosmicare visitors reported LSD use. Over 40% also presented multiple drug use. Pre-post mental state evaluation showed statistically significant difference (p<.05) confirming crisis resolution. Crisis episodes that presented no resolution were more often related with mental health outburst episodes, with psychoactive substance use or not. Visitors showed high satisfaction with intervention (n=58) and according to follow-up (n=18) this perception was stable over time. Crisis intervention was experienced as very significant. We discuss limitations and implications of evaluating natural setting based interventions, and the relation between psychoactive substance use and psychopathology. Other data on visitor’s profile and vulnerability to crisis showed inconclusive.

Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population

January 13, 2015 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, DMT, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , ,

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.

Making a medicine out of MDMA

January 5, 2015 / Anxiety Disorders / PTSD, MDMA, Neuroscience, Papers, Psychology, Publications / By / ,

Abstract

From its first use 3,4,-methylenedioxymethamphetamine (MDMA) has been recognised as a drug with therapeutic potential. Research on its clinical utility stopped when it entered the recreational drug scene but has slowly resurrected in the past decade. Currently there is enough evidence for MDMA to be removed from its Schedule 1 status of ‘no medical use’ and moved into Schedule 2 (alongside other misused but useful medicines such as heroin and amphetamine). Such a regulatory move would liberate its use as a medicine for patients experiencing severe mental illnesses such as treatment-resistant post-traumatic stress disorder.

Effects of ecstasy on cooperative behaviour and perception of trustworthiness: A naturalistic study

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

Abstract

Background: Acute recreational use of 3,4-methylenedioxymethamphetamine (MDMA; ‘ecstasy’) can promote pro-social effects which may alter interpersonal perceptions.

Aims: To explore such effects, this study investigated whether acute recreational use of ecstasy was associated with changes in individual perception of trustworthiness of people’s faces and co-operative behaviours.

Method: An independent group, repeated measures design was used in which 17 ecstasy users were tested on the night of drug use (day 0) and again three days later (day 3); 22 controls were tested on parallel days. On each day, participants rated the trustworthiness of 66 faces, carried out three co-operative behaviour tasks (public good; dictator; ultimatum game) and completed mood self-ratings.

Results: Acute ecstasy use was associated with increased face trustworthiness ratings and increased cooperative behaviour on the dictator and ultimatum games; on day 3 there were no group differences on any task. Self-ratings showed the standard acute ecstasy effects (euphoria, energy, jaw clenching) with negative effects (less empathy, compassion, more distrust, hostility) emerging on day 3.

Conclusions: Our findings of increased perceived trustworthiness and co-operative behaviours following use of ecstasy suggest that a single dose of the drug enhances aspects of empathy. This may in turn contribute to its popularity as a recreational drug and potentially to its enhancement of the therapeutic alliance in psychotherapy.

Acute effects of MDMA on autonomic cardiac activity and their relation to subjective prosocial and stimulant effects

September 10, 2014 / MDMA, Papers, Psychology, Publications / By / , , , ,

Abstract

MDMA is a stimulant with unique “prosocial” effects, the physiological and pharmacological mechanisms of which are unknown. Here, we examine the relationship of measures of parasympathetic and sympathetic nervous system activity to the prosocial effects of MDMA. Parasympathetic activity was measured using respiratory sinus arrhythmia (RSA) and sympathetic activity using pre-ejection period (PEP). Over three sessions, 33 healthy volunteers received placebo, 0.75 mg/kg, and 1.5 mg/kg MDMA under counterbalanced, double-blind conditions, while we measured subjective feelings, RSA, and PEP. RSA and PEP data were available for 26 and 21 participants, respectively. MDMA increased prosocial and stimulated feelings, decreased RSA, and decreased PEP. At 1.5 mg/kg, subjective prosocial effects correlated with stimulated feelings and PEP, but not RSA. This suggests sympathetic, rather than parasympathetic, effects relate to the prosocial effects of MDMA.

Acid Test: LSD, Ecstasy, and the Power to Heal

December 25, 2021 / LSD, MDMA / By

It’s no secret that psychedelic drugs have the ability to cast light on the miraculous reality hidden within our psyche. Almost immediately after the discovery of LSD less than a hundred years ago, psychedelics began to play a crucial role in the quest to understand the link between mind and matter. With an uncanny ability to reveal the mind’s remote frontiers and the unmapped areas of human consciousness, LSD and MDMA (better known as Ecstasy) have proven extraordinarily effective in treating anxiety disorders such as PTSD—yet the drugs remain illegal for millions of people who might benefit from them.

Anchoring Tom Shroder’s Acid Test are the stories of Rick Doblin, the founder and executive director of the Multidisciplinary Association for Psychedelic Studies (MAPS), who has been fighting government prohibition of psychedelics for more than thirty years; Michael Mithoefer, a former emergency room physician, now a psychiatrist at the forefront of psychedelic therapy research; and his patient Nicholas Blackston, a former Marine who has suffered unfathomable mental anguish from the effects of brutal combat experiences in Iraq. All three men are passionate, relatable people; each flawed, each resilient, and each eccentric, yet very familiar and very human.

Acid Test covers the first heady years of experimentation in the fifties and sixties, through the backlash of the seventies and eighties, when the drug subculture exploded and uncontrolled use of street psychedelics led to a PR nightmare that created the drug stereotypes of the present day. Meticulously researched and astoundingly informative, this is at once a personal story of intertwining lives against an epic backdrop, and a compelling argument for the unprecedented healing properties of drugs that have for decades been characterized as dangerous, illicit substances.

Tom Shroder has been an award-winning journalist, writer and editor for more than 30 years.
