Psilocybin Magic Mushrooms National Institute on Drug Abuse NIDA

It is important to note that while researchers are currently exploring the therapeutic uses for psilocybin and other psychedelics, these substances are only utilized in controlled research and medical settings under the supervision of trained professionals. Despite its status as a Schedule 1 controlled substance at the Federal level, possession of psilocybin has been either decriminalized or deprioritized in some states and the District of Columbia. Other states have proposed or enacted psilocybin-specific legislation to regulate its production, sale, or supervised administration. Generally, the recreational use of psilocybin refers to mushrooms containing psilocybin; synthetic production of psilocybin is complicated and expensive.

Psilocybin for Mental Health and Addiction: What You Need To Know

McGlothlin was part of a small, proof-of-concept trial using psilocybin to help heavy smokers quit[1] . Psilocybin (pronounced silo-sie-bin) is what makes magic mushrooms psychedelic and, despite its reputation as a recreational drug for hippies, it is showing promise as a therapeutic agent for a number of psychiatric illnesses including addiction, depression and anxiety. It is almost as though quitting smoking is peripheral during the experience,” says McGlothlin. Most studies examined involved healthy subjects, some included patients with anxiety, or OCD, and in one large study of participants in ayahuasca ceremonies, a small number were taking antidepressant medication.

Psychedelic drug helped people with alcohol use disorder reduce drinking, study shows

In contrast, people who had used psychedelics were less likely to have required mental health treatment in the past year than those who had not. The evidence for serious adverse events remains low and recent RCTs using psychedelics in various non-psychotic psychiatric disorders are showing good evidence for both safety and efficacy (Carhart-Harris et al., 2021; Palhano-Fontes et al., 2019). In contrast, scientific research consistently assesses psychedelics as much less harmful to the user as well as to society compared to alcohol and almost all other controlled substances.

1. The U.S. Food and Drug Administration has designated psilocybin as a "breakthrough therapy," and in 2023 loosened restrictions to allow drug developers and scientists to conduct clinical trials with the psychedelic substance.
2. Only 252 (28%) were actually hallucinogenic, while 275 (31%) were regular store-bought mushrooms laced with LSD or phencyclidine (PCP) and 328 (37%) contained no drug at all.
3. Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) comes from certain types of mushrooms found on nearly every continent.

Fast facts on psilocybin

For guidance from NCCIH on using PubMed, see How To Find Information About Complementary Health Approaches on PubMed. Current research suggests psilocybin is not addictive, and no physical symptoms occur after stopping use. Some people who take psilocybin may experience persistent, distressing alterations to how they see the world. These may take the form of a visual flashback, a traumatic recall of an intensely upsetting experience. "In my view, if a manufacturer wanted to develop a dietary supplement from Amanita muscaria, the application probably would not be approved because of muscimol and ibotenic acids' inherent risks," Leas said. "But right now it is the 'Wild West,' and companies are profiting from delayed enforcement while putting consumers at risk."

Milestone study launching the revival of psilocybin research

Studies suggest that psilocybin can temporarily disrupt communication among regions of the brain known as the default mode network, which is most active when we self-reflect. Reducing a person’s sense of self-awareness may lead to a greater feeling of openness and increased connectedness to the world. A “bad trip” can include feelings of despair, confusion, paranoia, anxiety, and panic.

Abuse liability

Throughout college, he would start drinking liquor in the morning, planning two-day hangovers into his schedule. In 2015, Jon Kostas of New York City signed up as one of the first participants after his mother told him about the trial. NYU Langone Health led the trial, which began recruiting in 2014, with researchers from the University of Alabama at Birmingham and the University of New Mexico. He believes the benefits of microdosing come from toggling between a psilocybin-impacted state and a sober state of consciousness, as this enables insights into different ways of being.

Associated Data

LSD has also been shown to be safe with very low physiological toxicity (Nichols, 2016). However, there have been cases of death by overdose of psychedelics with the majority from LSD (Fysh et al., 1985; Nichols and Grob, 2018) and psilocybin (Lim et al., 2012; Van Amsterdam et al., 2011) – probably because these are the most widely used. Yet, equally there are reports of ingesting large quantities of LSD with successful recovery and without long-lasting effects (Nichols and Grob, 2018).

Many of these risk perceptions originate from the first wave of psychedelic repression in the middle of last century often with sensationalised media reports. "The clinical trials, as it relates to the use of psilocybin for the treatment of depression in, for example, terminally ill patients or severe depression, are very, very interesting," she adds. "There's been an enormous amount of attention for the potential use of psychedelic drugs, for the treatment of depression, chronic relapsing disease post-traumatic stress disorder, [and] for the treatment of addictions," says Volkow. With controlled psychedelic substances, there is a potential to alter the entire brain for a period of time and thus provide relief from negative emotions that cloud the mind. Capturing this controlled relief, Dr Frederick Barrett's research suggests that, under the right conditions, psychedelics may have the potential to treat a wide range of mood and substance disorders.

It is important to seek professional help if you or someone you know is struggling with substance use disorder related to psychedelic mushrooms. While psychological dependence is possible, there are no documented cases of physical dependence and withdrawal symptoms. Moreover, no studies have documented any symptoms of physical dependence following psilocybin use. Physical dependence is when the body adapts to the presence of a substance, causing withdrawal symptoms to develop when an individual stops using it. On the contrary, psilocybin use has reportedly decreased withdrawal symptoms in individuals with cannabis, opioid and stimulant misuse disorder.

Today, in the United States, psilocybin is considered a psychedelic drug—a type of drug that affects how the brain processes a chemical called serotonin. Common street names for psilocybin are magic mushrooms, mushrooms, or shrooms. Preliminary research indicates that psilocybin may be helpful in treating substance use disorders, including tobacco use disorder. NIDA is funding a large, multi-site study on the effectiveness of psilocybin versus a nicotine patch, in combination with therapy, to help people stop smoking.

The results suggested that psilocybin produced a substantial and long lasting reduction in depression and anxiety, as well as increases in optimism and quality of life. While some people take magic mushrooms solely for their psychoactive effects, researchers have also explored psilocybin's potential therapeutic benefits. One study has suggested that psilocybin may be helpful for alcohol use disorder. A 2022 study compared the effect of psychotherapy plus two psilocybin sessions to psychotherapy plus placebo in 93 people with moderate alcohol use disorder. Participants who received the psilocybin-assisted psychotherapy had fewer heavy drinking days over 32 weeks, which suggests that psilocybin may be helpful for alcohol use disorder. Most people in the study correctly guessed which therapy they had received, however, and it is not known if the effect from psilocybin lasted longer than 32 weeks.

With work now underway, the center is aiming to enforce the strictest standards of scientific rigor on a field that many feel has veered uncomfortably close to mysticism and that has relied heavily on subjective reports. Early results have been promising and seem poised to keep the research on a roll. In addition, people with pre-existing mental health conditions may be more likely to experience adverse effects from psilocybin.

Alexander and Zand both emphasize that factors such as dosage, mindset, and setting can influence whether an individual experiences temporary psychosis during a psilocybin trip or not, and the subsequent nature of the experience. “The importance of caution and consulting with a mental health professional before using any psychoactive substance cannot be stressed enough, especially for those with a history of mental health concerns,” said hypertension Zand. However, Zand emphasizes that it’s vital to remember that the effects of psilocybin are temporary, and they typically subside as the trip wears off. Nutt, who was previously chair of the ACMD but was fired in 2009 because of his stance on drugs, is damning of the UK’s drugs laws, saying that the schedule 1 classification of many potentially useful compounds “is the biggest censorship of life sciences research in human history”.

Within the past 3 years, psilocybin and other organic psychedelics have been decriminalised in Denver, Colorado; Oakland, California; Santa Fe, California; Ann Arbor, Michigan; Somerville, Massachusetts; Washington, D.C.; and the state of Oregon. Going beyond decriminalisation, Oregon voters recently passed a bill giving the Oregon Health Authority 2 years to develop a division to regulate the production, distribution, administration and possession of psilocybin. In pre-clinical research, one experiment showed monkeys had no reliable interest in self-administering psilocybin. Self-administration is a common indicator for substance abuse, leading the authors to conclude psilocybin may only be mildly addictive, or may have a mix of both reinforcing and aversive effects. Clinical trials being conducted on September 2, 2022 evaluating the efficacy of psilocybin in substance-use disorders. Clinical trials evaluating the efficacy of psilocybin in substance-use disorders.

However, at least one psychedelic, lysergic acid diethylamide (LSD), can cause tolerance. Tolerance means that a person may need to take higher dosages to achieve the same effect. Psilocybin is not generally considered addictive nor does it tend to lead to compulsive use. Plus, people can build a tolerance to psilocybin fairly quickly, making it hard to have any effect after several days of repeated use. Tolerance also develops quickly with regular use, meaning that with regular use, a person will need more of the drug to achieve the same effect. This does not mean that shrooms are legal, but that the city is not permitted to "spend resources to impose criminal penalties" on people in possession of the drug.

Symptoms of mushroom poisoning may include muscle spasms, confusion, and delirium. A person should visit an emergency room immediately if these the link between alcohol use and suicide symptoms occur. Finally, though the risk is small, some psilocybin users risk accidental poisoning from eating a poisonous mushroom by mistake.

Activists in other states are watching Oregon’s experiment closely, including in Colorado, which is debuting a more relaxed system. Like Oregon, that state will license centers and facilitators but has also decriminalized the use and sharing of psilocybin and other psychedelics. Psychedelics seem to work in a different way from other treatments for addiction, such as nicotine replacement therapy, which target the same brain receptors as the drug patients are trying to wean themselves off. This difference may be central to why the treatment of addiction is just one of psilocybin’s potential uses. Recently, researchers have started to unpick its effects on brain function — with some striking results. Psilocybin decreases activity in the parts of the brain that are overactive in depression, addiction and ingrained behaviours.
