Not so fast. There’s a long way to go. But a study in London has shown that the active ingredient in magic mushrooms, psilocybin, may be effective against treatment resistant depression. Its effects were quick—within a week—and more than 40% of the patients treated were still in remission three months later.1 Yes, as far as it goes. These were people whose depression had …
“Alice remained looking thoughtfully at the mushroom for a minute, trying to make out which were the two sides of it; and as it was perfectly round, she found this a very difficult question”. To resolve the issue, Alice ate the mushroom; in more recent times, however, experimentation with psilocybin-containing magic mushrooms has been strongly discouraged. In the UK, in 2005, magic mushrooms...
BACKGROUND: Psilocybin is a serotonin receptor agonist that occurs naturally in some mushroom species. Recent studies have assessed the therapeutic potential of psilocybin for various conditions, including end-of-life anxiety, obsessive-compulsive disorder, and smoking and alcohol dependence, with promising preliminary results. Here, we aimed to investigate the feasibility, safety, and efficacy...
4-phosphorloxy-N,N-dimethyltryptamine (psilocybin) and methylenedioxymethamfetamine (MDMA), best known for their illegal use as psychedelic drugs, are showing promise as therapeutics in a resurgence of clinical research during the past 10 years. Psilocybin is being tested for alcoholism, smoking cessation, and in patients with advanced cancer with anxiety. MDMA is showing encouraging results as...
To date, pharmacological treatments for mood and anxiety disorders and for drug dependence show limited efficacy, leaving a large number of patients suffering severe and persistent symptoms. Preliminary studies in animals and humans suggest that ayahuasca, psilocybin and lysergic acid diethylamide (LSD) may have antidepressive, anxiolytic, and antiaddictive properties. Thus, we conducted a...
Tupper and colleagues highlight reasons for renewed interest in the use of psychedelic drugs as adjuncts to psychotherapy.[1][1] Clinicians have an interest in extending research into headache medicine, especially the treatment of cluster headaches (prevalence roughly 0.1%) when episodes are
The mixed serotonin (5-HT) 1A/2A/2B/2C/6/7 receptor agonist psilocybin dose-dependently induces an altered state of consciousness (ASC) that is characterized by changes in sensory perception, mood, thought, and the sense of self. The psychological effects of psilocybin are primarily mediated by 5-HT2A receptor activation. However, accumulating evidence suggests that 5-HT1A or an interaction...
Hallucinogenic mushrooms containing psilocin and psilocybin psychoactive compounds are permanent offers on the black market palette. Reliable quantifications of psilocin and psilocybin are especially important task of forensic analysis because their results have significant effect on the hardness of judgement to be punished by the court. For quantification of psilocybin mainly HPLC procedures...
Aims: We assessed long-term (>12 months) outcomes of psilocybin-facilitated smoking cessation, and qualitatively analyzed participants’ accounts to inform potential psychological mechanisms of treatment efficacy. Methods: Fifteen individuals who completed a pilot study of psilocybin-facilitated smoking cessation were invited for a long-term follow-up. Eleven (73%) returned and were interviewed...
Psilocybin has recently attracted a great deal of attention as a clinical research and therapeutic tool. The aim of this paper is to bridge two major knowledge gaps regarding its behavioural pharmacology – sex differences and the underlying receptor mechanisms. We used psilocin (0.25, 1 and 4 mg/kg), an active metabolite of psilocybin, in two behavioural paradigms – the open-field test and...
