This study aims to… 

Adverse events in clinical treatments with serotonergic psychedelics and MDMA: A mixed-methods systematic review

AEs are poorly defined in the context of psychedelic treatments and are probably underreported in the literature due to study design (lack of systematic assessment of AEs) and sample selection.

Classic psychedelics are a loosely grouped class of drugs that activate serotonin 5HT2A receptors to induce complex behavioral, psychological, and physiological effects [1]; 5HT2A agonism induces the

Therapeutic uses of psychedelics for eating disorders and body dysmorphic disorder

It is highlighted that more research is needed to determine the safety and efficacy of psychedelics in BDD and EDs and ways to suggest avenues for future exploration are suggested.

Acute, subacute and long-term subjective effects of psilocybin in healthy humans: a pooled analysis of experimental studies

The results suggest that the administration of moderate doses of psilocybin to healthy, high-functioning and well-prepared subjects in the context of a carefully monitored research environment is associated with an acceptable level of risk.

Acute Effects of Lysergic Acid Diethylamide in Healthy Subjects

Psilocybin can occasion mystical-type experiences having substantial and sustained personal meaning and spiritual significance

When administered under supportive conditions, psilocybin occasioned experiences similar to spontaneously occurring mystical experiences, and the ability to occasion such experiences prospectively will allow rigorous scientific investigations of their causes and consequences.

A Review of Hallucinogen Persisting Perception Disorder (HPPD) and an Exploratory Study of Subjects Claiming Symptoms of HPPD.

Results of the survey suggest that HPPD is in most cases due to a subtle over-activation of predominantly neural visual pathways that worsens anxiety after ingestion of arousal-altering drugs, including non-hallucinogenic substances.

Distinct acute effects of LSD, MDMA, and d-amphetamine in healthy subjects

Investigation of the acute autonomic, subjective, and endocrine effects of single doses of LSD, MDMA, and d-amphetamine in 28 healthy subjects indicates clearly distinct acute effects and may assist the dose-finding in substance-assisted psychotherapy research.
