Psychedelics: The New Kid on the Block
HISTORY In the early part of twentieth century, these molecules were known as psychotomimetics, meaning that they create a state similar to psychosis. Later on, they were also termed as hallucinogens, but psychedelics usually do not cause hallucinations at a therapeutic dose. The name psychedelics for these substances was first given by Osmond in 1957, meani...
A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability and Efficacy of Psilocybin-Assisted Psychotherapy in Treating Severe Depression Among Adults With Post-Traumatic Stress Disorder (PTSD).
Post-Traumatic Stress Disorder (PTSD) is a mental disorder that may develop in people who have been exposed to a traumatic event, including actual or threatened death, serious injury, or sexual violence. Exposure to a traumatic event is defined as directly experiencing the event, learning about the event, or repeated exposure to details of the event. PTSD is...
Effects and Therapeutic Potential of Psilocybin in Alcohol Dependence
This trial is an open-label pilot study (N = 10) designed to assess the effects of psilocybin in alcohol dependent participants, demonstrate the feasibility of the integrated behavioral/pharmacologic intervention, and provide preliminary outcome and safety data. Participants will receive psilocybin orally in two all-day administration sessions, conducted in ...
Medications for the Treatment of Alcohol Dependence-Current State of Knowledge and Future Perspectives from a Public Health Perspective.
No single effective therapy for alcohol abuse has been found, despite it being a serious sociological and economic problem for hundreds of years. It seems difficult to find a single drug as a panacea for the alcohol problem due to the complexity of the pathophysiology of alcohol dependence. The purpose of this narrative review is to review existing and poten...
A Double-Blind Trial of Psilocybin-Assisted Treatment of Alcohol Dependence
Several lines of evidence suggest that classic hallucinogens such as psilocybin can facilitate behavior change in addictions such as alcohol dependence. The proposed investigation is a multi-site, double-blind active-controlled trial (n = 180, 90 per group) contrasting the acute and persisting effects of psilocybin to those of diphenhydramine in the context ...
Psilocybin for alcohol use disorder: Rationale and design considerations for a randomized controlled trial.
Several lines of evidence suggest that classic psychedelics (5-HT2A receptor agonists or partial agonists) such as psilocybin might facilitate behavior change in individuals with substance use disorders. We conducted a multi-site, double-blind, randomized controlled trial (RCT) to assess the effects of psilocybin-assisted psychotherapy in alcohol-dependent v...
Prevalence and associations of classic psychedelic-related seizures in a population-based sample.
Previous studies have reported links between classic psychedelic use and seizures, but little remains known about prevalence and potential risk factors of classic psychedelic-related seizures. Using a sample representative of the US adult population with regard to sex, age, and ethnicity (N = 2822), this study examined the prevalence and potential risk facto...
Percentage of Heavy Drinking Days Following Psilocybin-Assisted Psychotherapy vs Placebo in the Treatment of Adult Patients With Alcohol Use Disorder: A Randomized Clinical Trial.
ImportanceAlthough classic psychedelic medications have shown promise in the treatment of alcohol use disorder (AUD), the efficacy of psilocybin remains unknown.ObjectiveTo evaluate whether 2 administrations of high-dose psilocybin improve the percentage of heavy drinking days in patients with AUD undergoing psychotherapy relative to outcomes observed with a...
Psychedelics for Psychiatric Disorders: Promise, Not Panacea
Initial promise and dire need have inspired the multiple research programs of the second psychedelic renaissance. Serotonergic psychedelics (psilocybin, lysergic acid diethylamide, and ayahuasca) have decreased end-of-life anxiety in cancer patients, treatment-resistant depression, alcohol dependence, social anxiety in autistic adults, and nicotine dependenc...
Psychedelic use in India, its pattern and personal significance - findings from an online survey
Sir, Psychedelic studies have reported positive results for depression and anxiety related to cancer and other life-threatening illnesses, treatment-resistant depression, and tobacco and alcohol dependence.[1] Although there are no active psychedelic research studies going on in India, there is growing interest about these substances as evident by numerous s...
Many Drugs of Abuse May Be Acutely Transformed to Dopamine, Norepinephrine and Epinephrine In Vivo.
It is well established that a wide range of drugs of abuse acutely boost the signaling of the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis, where norepinephrine and epinephrine are major output molecules. This stimulatory effect is accompanied by such symptoms as elevated heart rate and blood pressure, more rapid breathing, in...
Psychedelics and psychiatric disorders: A emerging role
Introduction Recently there has been renewal in interest of psychedelic research. Classic psychedelics such as lysergic acid diethylamide (LSD), psilocybin and mescaline act pharmacologically as agonists at the 5-HT2A receptor. The entactogens like methylenedioxymethamphetamine (MDMA), acts as a serotonin, dopamine and noradrenaline agonist. All of these dru...
Psychedelics: A new era of treatment?
Introduction Psychedelics - including LSD (lysergic acid diethylamide), psilocybin, DMT (N, N-dimethyltryptamine), ayahuasca and mescaline - have an ancient history across various civilizations. In 1950, after LSD’s discovery by Hofmann, psychedelics enjoyed a short-lived relationship with psychiatry, before prohibitive legislature emerging in response to th...
What can we learn from the history of research on psychedelic drugs in the addictions?
The history of research on the use of psychedelic drugs to treat alcohol dependence in the 1950s and 1960s suggests the need for caution in their proposed clinical use. Since 2006 there has been a revival of interest in using psychedelics to treat depression and post-traumatic stress disorders [1] and the addictions [2]. What lessons may we glean from resear...
[Efficacy of psychedelics in psychiatry, a systematic review of the literature].
ObjectivesPsychedelics are powerful psychoactive substances. Natural psychedelics have been used for millennia by human civilizations, in particular in Latin America, while synthetic psychedelics were discovered in the 50s, giving rise to a lot of research before they were prohibited. More recently, their therapeutic properties have been studied especially t...
Cannabis-induced oceanic boundlessness.
BackgroundDespite tetrahydrocannabinol (THC)'s reputation for creating dramatic effects at high doses, empirical work rarely addresses cannabis's impact on subjective responses common to the tryptamine psychedelics. We focused on these effects because they have preceded and covaried with the therapeutic impact of psilocybin in previous work.AimsThe current s...
Efficacy, tolerability, and safety of serotonergic psychedelics for the management of mood, anxiety, and substance-use disorders: a systematic review of systematic reviews.
IntroductionMood, anxiety, and substance-use disorders are among the most prevalent psychiatric disorders in the population. Although several pharmacological treatments are available, they are not effective for a significant proportion of patients and are associated with several adverse reactions. Therefore, new treatments should be explored. Recent studies ...

Research on the clinical applications of psychedelic-assisted psychotherapy has demonstrated promising early results for treatment of alcohol dependence. Detailed description of the content and methods of psychedelic-assisted psychotherapy, as it is conducted in clinical settings, is scarce. Methods: An open-label pilot (proof-of-concept) study of psilocybin...
