Experienced Drug Users Assess the Relative Harms and Benefits of Drugs: A Web-Based Survey

Journal of Psychoactive Drugs September 1, 2013 Robin Lester Carhart-Harris, David John Nutt 55 citations

A web-based survey was used to consult the opinions of experienced drug users on matters related to drug harms. We identified a rare sample of 93 drug users with personal experience with 11 different illicit drugs that are widely used in the UK. Asked to assess the relative harms of these drugs, they ranked alcohol and tobacco as the most harmful, and three "Class A" drugs (MDMA, LSD, and...

Salvia divinorum: from Mazatec medicinal and hallucinogenic plant to emerging recreational drug.

Human Psychopharmacology: Clinical and Experimental September 1, 2013 Jolanta B. Zawilska, Jakub Wojcieszak 34 citations

Salvia divinorum is a sage endemic to a small region of Mexico and has been traditionally used by the Mazatec Indians for divination and spiritual healing. Recently, it has gained increased popularity as a recreational drug, used by adolescents and young adults as an alternative to marijuana and LSD. Salvinorin A, the major active ingredient of the plant, is considered to be the most potent...

Psychedelics and Mental Health: A Population Study

PLoS One August 19, 2013 Teri Suzanne Krebs, Pål-ørjan Johansen 338 citations

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...

Drug laws and the 'derivative' problem

Drug Testing and Analysis August 15, 2013 Leslie A. King, István Ujváry, Simon D. Brandt 8 citations

The concept of a 'derivative' is used widely in chemistry, where its precise meaning depends on the circumstances. However, numerous examples of derivative also occur in domestic drugs legislation, some of which stem from the 1961 United Nations Single Convention on Narcotic Drugs. There is a commonly held view that only 'first-order' derivatives should be considered: substances that can be...

Psychedelic‐Induced Experiences

August 9, 2013 James Fadiman, Andrew Kornfeld

This chapter considers how psychedelic substances affect consciousness, using the lens of a transpersonal approach to psychology. Transpersonal psychology's point of view is especially suitable to grapple with this question due not only to its continuing interest in altered states of consciousness, but also to its long-standing relationship with psychedelic research. Mainstream psychology has...

Methoxetamine (MXE) – A Phenomenological Study of Experiences Induced by a “Legal High” from the Internet

Journal of Psychoactive Drugs July 1, 2013 Anette Kjellgren, Kristoffer Jonsson 75 citations

Methoxetamine (MXE), a ketamine analogue, is one of the new "legal highs" sold on the Internet. The aim of this qualitative study was to provide an initial understanding of what characterizes the experiences induced by MXE. Anonymously written reports (33 persons) on the effects of MXE were collected from public Internet forums and analyzed using the Empirical Phenomenological Psychological...

A survey of hallucinogenic mushroom use, factors related to usage, and perceptions of use among college students.

Drug and Alcohol Dependence June 1, 2013 Robert M. Hallock, Andrew Dean, Zachary A Knecht et al.

Recreational usage and attitudes toward psilocybin-containing hallucinogenic mushrooms among college students are seldom explored. We surveyed 882 randomly selected undergraduates at Skidmore College in upstate New York and quantified whether participants had ever used psilocybin mushrooms, their attitudes toward the drug, and polydrug use. There were 409 responses and 29.5% of the sample...

Enhanced prefrontal serotonin 2A receptor signaling in the subchronic phencyclidine mouse model of schizophrenia.

Journal of Neuroscience Research May 1, 2013 Martin A. Santini, Cecilia Ratner, Susana Aznar et al.

Prefrontal serotonin 2A receptors (5-HT2A Rs) have been linked to the pathogenesis and treatment of schizophrenia. Many antipsychotics fully occupy 5-HT2A R at clinical relevant doses, and activation of 5-HT2A receptors by lysergic acid diethylamide (LSD) and LSD-like drugs induces a schizophrenia-like psychosis in humans. Subchronic phencyclidine (PCP) administration is a well-established...

Novel Drugs of Abuse: A Snapshot of an Evolving Marketplace.

Adolescent Psychiatry April 1, 2013 Ryan Vandrey, Matthew W Johnson, Patrick S Johnson et al. 26 citations

Over the past decade, non-medical use of novel drugs has proliferated worldwide. In most cases these are synthetic drugs first synthesized in academic or pharmaceutical laboratories for research or drug development purposes, but also include naturally occurring substances that do not fit the typical pharmacological or behavioral profile of traditional illicit substances. Perhaps most unique to...
