Psilocybine and Substance Abuse Detection

Psychedelic-assisted therapy could transform treating psychiatric illness, but harms from exacerbating substance use disorder (SUD) among adults with psychiatric illness using psychedelics have not been studied. A cross-sectional survey in the US was used to test whether Drug Abuse Screening Test scores (DAST-10, validated instrument predicting SUD...

Psilocybe semilanceata belongs to the genus of Psilocybe; it is a hallucinogenic fungus, frequently found in regions with high rainfall, in the grass and moss. There are estimated to be as many as eight Psilocybe hallucinogenic species containing psychoactive alkaloids, such as psilocybin and psilocin, which may cause visual, auditory and other hal...

A confirmatory method for the determination of illicit drugs based on micro-solid phase extraction with modified tips, made of a functionalized fiberglass with apolar chains of octadecylsilane into monolithic structure, has been developed in this study. Drugs belonging to different chemical classes, such as amphetamine, methamphetamine, methylenedi...

"Magic mushroom (MM)" is the name most commonly given to psychoactive fungi containing the hallucinogenic components: psilocin (1) and psilocybin (2). We investigated the rRNA gene (internal transcribed spacer (ITS) and large subunit (LSU)) of two Panaeolus species and four Psilocybe species fungi (of these, two are non-psilocybin species). On the...

Ion mobility spectrometry (IMS) has been known as an analytical technique since the late 1960s and early 1970s. To date, it has been successfully utilized for the detection of environmental pollutants, warfare agents, explosives, herbicides, pesticides, petroleum products as well as for the detection of prescription and illicit drugs. In this paper...

Psilocin was identified in a urine specimen collected during a routine driving under the influence of drugs investigation, the first for this laboratory. The subject did not exhibit any response to an automobile crash, indicating the he may have been unaware of the severity of the situation or his immediate surroundings. The urine specimen gave a p...

Substance abuse is a major health and behavioral concern in college students. Alcohol and marijuana are the most commonly abused drugs on college campuses. Others include tobacco, 3,4-methylenedioxymethamphetamine, gamma-hydroxybutyrate, flunitrazepam (Rohypnol), lysergic acid, ketamine, methamphetamine, phencyclidine, cocaine, and psilocybin mushr...

After the immunisation of rabbits with a psilocin-specific immunogen, polyclonal antisera were obtained. With these antisera a competitive, heterogeneous radioimmunoassay for the detection of psilocin was developed. As tracer a derivative of psilocin was synthesised, which contained a tritiated CH(3) group. The antisera showed a specific reaction w...

Driving under the influence of drugs is an issue of growing concern in the industrialized countries as a risk and a cause for road accidents. In forensic toxicology, the increasing number of samples for determination of drugs in blood is mainly due to zero-tolerance laws in several countries and well-trained police officers who can better recognize...

Pharmacokinetic studies of psilocybin in humans have shown the rapid dephosphorylation of psilocybin to psilocin with further conversion to 4-hydroxy-tryptophole (4HT) and 4-hydroxyindole-3-acetic acid (4HIAA) in plasma. Our study shows that psilocin also undergoes conjugation and can be found in the urine as the psilocin-glucuronide conjugate. Rec...

Active compounds of some mushrooms e.g. Psilocybe cubensis, Paneolus subalteatus or Stropharia coronilla, the psychotropic agents psilocybin and psilocin, have hallucinogenic effects. In one case of 'magic mushroom' intake, we had to analyse blood and urine. Psilocin was detected in the urine with REMEDi HS. Most of the psilocin was excreted as the...

'Magic mushrooms' is the name most commonly given to psychoactive fungi containing the hallucinogenic components psilocybin and psilocin. Material confiscated by local authorities was examined using morphologic, microscopic, microchemical, and toxicological methods. Psilocybe cubensis was the most popular mushroom in the sample collective, followed...
