Lifetime experience with (classic) psychedelics predicts pro-environmental behavior through an increase in nature relatedness. (Forstmann M & Sagioglou C, 2017)
Julkaisu:Journal of Psychopharmacology
Tiivistelmä: In a large-scale (N = 1487) general population online study, we investigated the relationship between past experience with classic psychedelic substances (e.g. LSD, psilocybin, mescaline), nature relatedness, and ecological behavior (e.g. saving water, recycling).

Using structural equation modeling we found that experience with classic psychedelics uniquely predicted self-reported engagement in pro-environmental behaviors, and that this relationship was statistically explained by people's degree of self-identification with nature. Our model controlled for experiences with other classes of psychoactive substances (cannabis, dissociatives, empathogens, popular legal drugs) as well as common personality traits that usually predict drug consumption and/or nature relatedness (openness to experience, conscientiousness, conservatism).

Although correlational in nature, results suggest that lifetime experience with psychedelics in particular may indeed contribute to people's pro-environmental behavior by changing their self-construal in terms of an incorporation of the natural world, regardless of core personality traits or general propensity to consume mind-altering substances. Thereby, the present research adds to the contemporary literature on the beneficial effects of psychedelic substance use on mental wellbeing, hinting at a novel area for future research investigating their potentially positive effects on a societal level. Limitations of the present research and future directions are discussed.

Psychedelics, Personality and Political Perspectives. (Nour MM, Evans L, Carhart-Harris RL, 2017)
Julkaisu:Journal of Psychoactive Drugs
Tiivistelmä: The psychedelic experience (including psychedelic-induced ego dissolution) can effect lasting change in a person's attitudes and beliefs. Here, we aimed to investigate the association between naturalistic psychedelic use and personality, political perspectives, and nature relatedness using an anonymous internet survey.

Participants (N = 893) provided information about their naturalistic psychedelic, cocaine, and alcohol use, and answered questions relating to personality traits of openness and conscientiousness (Ten-Item Personality Inventory), nature relatedness (Nature-Relatedness Scale), and political attitudes (one-item liberalism-conservatism measure and five-item libertarian-authoritarian measure). Participants also rated the degree of ego dissolution experienced during their "most intense" recalled psychedelic experience (Ego-Dissolution Inventory).

Multivariate linear regression analysis indicated that lifetime psychedelic use (but not lifetime cocaine use or weekly alcohol consumption) positively predicted liberal political views, openness and nature relatedness, and negatively predicted authoritarian political views, after accounting for potential confounding variables. Ego dissolution experienced during a participant's "most intense" psychedelic experience positively predicted liberal political views, openness and nature relatedness, and negatively predicted authoritarian political views.

Further work is needed to investigate the nature of the relationship between the peak psychedelic experience and openness to new experiences, egalitarian political views, and concern for the environment.

Psychedelic drug use in healthy individuals: A review of benefits, costs, and implications for drug policy (Elsey JWB, 2017)
Julkaisu:Drug Science, Policy and Law
Tiivistelmä: The potential of psychedelic drugs in the treatment of mental health problems is increasingly being recognized. However, relatively little thrust has been given to the suggestion that individuals without any mental health problems may benefit from using psychedelic drugs, and that they may have a right to do so.

This review considers contemporary research into the use of psychedelic drugs in healthy individuals, including neurobiological and subjective effects.

In line with findings suggesting positive effects in the treatment of mental health problems, such research highlights the potential of psychedelic drugs for the enhancement of wellbeing even in healthy individuals. The relatively low risk associated with usage does not appear to align with stringent drug laws that impose heavy penalties for their use. Some policy implications, and suggestions for future research, are considered.

Psychedelics and Mental Health: A Population Study (Krebs TS & Johansen PØ, 2013)
Julkaisu:PLoS One
Tiivistelmä: BACKGROUND:
The classical serotonergic psychedelics LSD, psilocybin, mescaline are not known to cause brain damage and are regarded as non-addictive. Clinical studies do not suggest that psychedelics cause long-term mental health problems. Psychedelics have been used in the Americas for thousands of years. Over 30 million people currently living in the US have used LSD, psilocybin, or mescaline.

To evaluate the association between the lifetime use of psychedelics and current mental health in the adult population.

Data drawn from years 2001 to 2004 of the National Survey on Drug Use and Health consisted of 130,152 respondents, randomly selected to be representative of the adult population in the United States. Standardized screening measures for past year mental health included serious psychological distress (K6 scale), mental health treatment (inpatient, outpatient, medication, needed but did not receive), symptoms of eight psychiatric disorders (panic disorder, major depressive episode, mania, social phobia, general anxiety disorder, agoraphobia, posttraumatic stress disorder, and non-affective psychosis), and seven specific symptoms of non-affective psychosis. We calculated weighted odds ratios by multivariate logistic regression controlling for a range of sociodemographic variables, use of illicit drugs, risk taking behavior, and exposure to traumatic events.

21,967 respondents (13.4% weighted) reported lifetime psychedelic use. There were no significant associations between lifetime use of any psychedelics, lifetime use of specific psychedelics (LSD, psilocybin, mescaline, peyote), or past year use of LSD and increased rate of any of the mental health outcomes. Rather, in several cases psychedelic use was associated with lower rate of mental health problems.

We did not find use of psychedelics to be an independent risk factor for mental health problems.

Harm potential of magic mushroom use: a review. (van Amsterdam J, Opperhuizen A, van den Brink W, 2011)
Julkaisu:Regulatory Toxicology and Pharmacology
Tiivistelmä: In 2007, the Minister of Health of the Netherlands requested the CAM (Coordination point Assessment and Monitoring new drugs) to assess the overall risk of magic mushrooms.

The present paper is an updated redraft of the review, written to support the assessment by CAM experts. It summarizes the literature on physical or psychological dependence, acute and chronic toxicity, risk for public health and criminal aspects related to the consumption of magic mushrooms.

In the Netherlands, the prevalence of magic mushroom use was declining since 2000 (last year prevalence of 6.3% in 2000 to 2.9% in 2005), and further declined after possession and use became illegal in December 2008. The CAM concluded that the physical and psychological dependence potential of magic mushrooms was low, that acute toxicity was moderate, chronic toxicity low and public health and criminal aspects negligible. The combined use of mushrooms and alcohol and the quality of the setting in which magic mushrooms are used deserve, however, attention.

In conclusion, the use of magic mushrooms is relatively safe as only few and relatively mild adverse effects have been reported. The low prevalent but unpredictable provocation of panic attacks and flash-backs remain, however, a point of concern.

A review of the acute subjective effects of MDMA/ecstasy. (Baylen CA, Rosenberg H, 2006)
Tiivistelmä: AIM:
Although several relatively recent reviews have summarized the neuropsychiatric effects associated with chronic ecstasy use, there is no published comprehensive review of studies on the acute subjective effects (ASEs) of MDMA/ecstasy.

The present study reviewed the prevalence, intensity and duration of ASEs collected from 24 studies that provided frequency data on the prevalence of self-reported ecstasy effects and/or provided data on the intensity of ecstasy effects.

Although hundreds of ASEs have been reported following MDMA consumption, we identified a subset of effects reported repeatedly by meaningful proportions and large numbers of participants across multiple investigations, most of which were either emotional (e.g. anxiety, depression, closeness, fear, euphoria, calmness) or somatic (e.g. nausea/vomiting, bruxism, muscle aches/headache, sweating, numbness, body temperature changes, fatigue, dizziness, dry mouth, increased energy). Only one sexual ASE (sexual arousal/increased sensual awareness), one cognitive ASE (confused thought), one sensory-perceptual ASE (visual effects/changes in visual perception), one sleep-related ASE (sleeplessness) and one appetite-related ASE (decreased appetite) were reported across five or more investigations. Three factors-number of hours between ingestion and assessment, dose level, and gender-have been associated with the acute subjective experience of MDMA/ecstasy.

This review provides useful information for clinicians and researchers who want to understand the desirable and undesirable ASEs that may motivate and restrain ecstasy use, for public health advocates who seek to reduce biomedical harms (e.g. fainting, dehydration, shortness of breath, bruxism) associated with recreational use of MDMA/ecstasy, and for educators who wish to design credible prevention messages that neither underestimate nor exaggerate users' experiences of this drug.
