This "Designer Drugs 2.0" issue of Clinical Pharmacology & Therapeutics focuses on novel psychoactive substances, primarily cannabinoids and cathinones, and the repurposing of established psychoactive compounds (e.g., modafinil, psilocybin, lysergic acid diethylamide, and 3,4-methylenedioxymethamphetamine) that simultaneously offer new pharmacotherapies and ...
In medicine we must always expect the unexpected. Medicine is replete with paradoxes, where poisons become cures. Snake venom is deadly but is being used to treat some cancers, (1) because it produces contortrostatin, a protein that paralyzes cancer cells and prevents them from migrating. Venoms from spiders are being investigated as a treatment to slow the ...
AimThere have been significant changes in adolescent consumption habits over the past fifteen years. New molecules have been synthesized, new devices created and a number of products have increased in popularity; and as a result clinicians sometimes lack information. We chose to focus on this population because of its vulnerability, as adolescents show low s...
Drug abuse is a worldwide problem. Although commonly abused drugs can be identified during routine urine drug testing, less commonly abused drugs may escape detection. These less commonly abused drugs not only include some designer drugs such as synthetic cannabinoid but also include abuse of psychedelic magic mushroom (active ingredients: psilocybin and psi...
BackgroundA recent open-label pilot study (N = 15) found that two to three moderate to high doses (20 and 30 mg/70 kg) of the serotonin 2A receptor agonist, psilocybin, in combination with cognitive behavioral therapy (CBT) for smoking cessation, resulted in substantially higher 6-month smoking abstinence rates than are typically observed with other medicati...
Aim of the studyBased on an abundance of information on the internet, psychotropic plants and mushrooms are of increasing relevance as legal and cheap alternatives to other illicit drugs. Due to the lack of a German database, the abuse of selected biogenic drugs using reported exposures to 3 German Poison Information Centres (PICs) was examined.MethodsInform...
Light microscopical examination of plant and fungal remains in the post mortem gut may be capable of demonstrating the ingestion of unexpected natural psychotropic materials. This is demonstrated here in a case in which a 'shaman' was accused of causing the death of a young man. The deceased had participated in a ceremony which involved the drinking of ayahu...
A procedure based on ultra-high-pressure liquid chromatography tandem mass spectrometry has been developed for the determination of mescaline, N,N-dimethyltryptamine, psilocin, psilocybin, salvinorin A in hair of consumers of psychedelic vegetal material such peyote or trichocereus cacti, psilocybe mushrooms, Salvia divinorum or psychedelic beverage ayahuasc...
Covering: up to December 2013. Over the past decade, there has been a growing transition in recreational drugs from natural materials (marijuana, hashish, opium), natural products (morphine, cocaine), or their simple derivatives (heroin), to synthetic agents more potent than their natural prototypes, which are sometimes less harmful in the short term, or tha...

Psilocybin-occasioned mystical experiences have been linked to persisting effects in healthy volunteers including positive changes in behavior, attitudes, and values, and increases in the personality domain of openness. In an open-label pilot-study of psilocybin-facilitated smoking addiction treatment, 15 smokers received 2 or 3 doses of psilocybin in the co...

This paper presents original research on prevalence, user characteristics and effect profile of N,N-dimethyltryptamine (DMT), a potent hallucinogenic which acts primarily through the serotonergic system. Data were obtained from the Global Drug Survey (an anonymous online survey of people, many of whom have used drugs) conducted between November and December ...
Current treatments for addiction are frequently ineffective. Hallucinogenic therapy has been indicated as helpful for a range of substance use disorders, yet this approach remains understudied and publicly unavailable. It is nonetheless a promising treatment, which has significant, long-term beneficial effects with single doses and a profile characterized by...
Psychoactive drugs of fungal origin, psilocin, ibotenic acid, and muscimol among them have been proposed for recreational use and popularized since the 1960s, XX century. Despite their well-documented neurotoxicity, they reached reputation of being safe and nonaddictive. Scientific efforts to find any medical application for these hallucinogens in psychiatry...
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 Empiric...
