Background:: Lysergic acid diethylamide (LSD) and psilocybin are serotonergic hallucinogens that are used primarily for recreational abuse. Small studies evaluated the efficacy of LSD and psilocybin for several psychiatric conditions. There are limited safety or toxicity data for either of these substances, especially in large populations. Read More

Ingestion of wild and potentially toxic mushrooms is common in the United States and many other parts of the world. US poison centers have been logging cases of mushroom exposure in The National Poison Data System (NPDS) annual publications for over 30 years. This study compiles and analyzes US mushroom exposures as reported by the NPDS from 1999 to 2016. Read More

Introduction: Synthetic Cannabinoid Receptor Agonists (SCRAs) are the largest group of new psychoactive substances reported to the European Warning System and the United Nations Office on Drugs and Crime to date. The heterogeneous nature and speed of diversification of these compounds make it challenging to accurately characterise and predict harms of these compounds in pre-clinical studies, ahead of their appearance.

Case Report: We report the case of a 19-year-old female who purchased three products from a headshop: two new psychoactive substances (sachets of "cannabis tea" and "mushroom tea") as well as two LSD blotters. Read More

This paper is a review of the new studies or new explanations of the hallucinogenic mushrooms, regarding their diversity, history, traditions, and problems in their recreational use, new taxonomic studies, and their modern applications in medicine, all of them since the 1970s to the present.

The pharmacological activities and acute toxicity of the psilocin (PC) and dried residues of the crude extracts of psychotropic mushrooms were investigated in mice. The hallucinogenic substances were effectively isolated, by using methanol, from the species of Psilocybe semilanceata and Pholiotina cyanopus, that were collected in the north-east region of Poland. The chemical analysis of these extracts, which was performed by liquid chromatography with mass spectrometry detection (LC-MS), indicated the presence of psilocin and other hallucinogenic substances, including indolealkylamines and their phosphorylated analogues.

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. Read More

A 28-year-old man with a history of drug and alcohol abuse presented multiple times to the hospital over 2 months with an elusive constellation of symptoms, resolving spontaneously in each instance. This patient required a high level of care for management and stabilization, including 3 emergency department visits, 2 medical floor admissions, and 1 intensive care unit admission. In both the emergency department and inpatient setting, all laboratory and imaging study results, including gas chromatography/mass spectrophotometry of the urine, were negative/normal. Read More

Two young men, 25 and 32 years old, presented with severe automutilation by knife wounds after consumption of hallucinogenic mushrooms. The first patient had also used cocaine, cannabis and alcohol, while the second patient had only used the hallucinogenic mushrooms. Both patients were treated symptomatically and survived despite their severe stab wounds. Read More

The major syndromes of mushroom poisoning can be divided by presentation timing: Early syndromes (symptom onset <6 hrs after ingestion) have little probability to cause organ damage. Epigastric pain, nausea, vomiting and diarrhea occur in most cases and treatment includes initial gastrointestinal decontamination with oral activated charcoal and fluid rehydration. In addition, an acute gastrointestinal syndrome can be combined with cholinergic toxicity, epileptiformic response or immuno-hemolytic anemia. Read More

Natural hallucinogens (including Psilocybe mushrooms) became popular in Europe since the nineties. They have been in the focus of clinicians interest for years because of their biological effects. Mechanism of action of these hallucinogens, both Psilocin and Psilocibin, is based on the physiological structure similarity to human neurotransmitters as serotonin and catecholamines. Read More

The group of hallucinogenic mushrooms (species of the genera Conocybe, Gymnopilus, Panaeolus, Pluteus, Psilocybe, and Stropharia) is psilocybin-containing mushrooms. These "magic", psychoactive fungi have the serotonergic hallucinogen psilocybin. Toxicity of these mushrooms is substantial because of the popularity of hallucinogens. Read More

MDMA ("Ecstasy") and its analogues such as MDE and MDA are amphetamine derivatives reported to produce an altered state with emotional overtones. Since more than ten years, ecstasy is after cannabis the most frequently used recreational drug by young adults, particularly in the so-called techno-scene. However, according to a recent survey there is an increasing trend for a revival of classic amphetamine and hallucinogen abuse, possibly due to the concern about the potential neurotoxicity and somatic risks associated with ecstasy use.

There are a lot of medical applications of psychotropic plants. However, there are many more mushrooms and plants with psychotropic effects considered useless by scholar medicine. The resulting regulations make the users criminal law breakers. Read More

Case Report: Intentional intoxication with natural hallucinogenic substances such as hallucinogenic mushrooms continues to be a major problem in the US and Europe, particularly in the harbor complex of northwest Poland (Pomerania). A case is described of Psilocybe intoxication in an 18-year-old man resulting in Wolff-Parkinson-White syndrome, arrhythmia, and myocardial infarction. The indole concentrations of hallucinogenic mushrooms may predict the risk for adverse central nervous system and cardiac toxicity. Read More

Cases involving the investigation of psylocybin-containing mushrooms became more frequent in forensic chemical and criminological expert evaluation in recent years. The authors present the data on the main chemical factors contained in these mushrooms, on the mechanism of their toxic effect, clinical picture of poisoning, and methods of chemical and toxicological analysis.

Despite its illegality, mushroom use as a hallucinogen is widespread. The reported toxicity of hallucinogenic mushrooms ranges from significant to relatively harmless. The greatest danger lies in the potential for mistaking a highly poisonous variety that contains cyclopeptides for the relatively innocuous hallucinogenic varieties. Read More
