Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are a type of hallucinogenic mushroom that contains the prodrug psilocybin, which turns into the psychedelic compound psilocin upon ingestion. Psilocybin is broken down by the liver and the resulting psilocin is responsible for the psychedelic effects of these mushrooms. The most potent species are members of the genus Psilocybe, such as P. azurescens, P. semilanceata, and P. cyanescens. However, psilocybin has also been found in several other genera, including Panaeolus, Inocybe, Pluteus, Gymnopilus, and Pholiotina. Psilocybin mushrooms have been used for hundreds or thousands of years by Indigenous groups for spiritual and cultural purposes and are currently being studied for their potential therapeutic benefits in treating mental health disorders.

What You'll Learn
Magic mushrooms
The use of magic mushrooms can result in a range of physical and psychological effects. Physically, users may experience nausea, vomiting, muscle weakness, drowsiness, pupil dilation, and increased heart rate. Psychologically, magic mushrooms can induce hallucinations, distort the sense of reality, mix up the senses, and intensify emotional responses. The effects of magic mushrooms typically appear within 15 to 45 minutes of ingestion and can last up to six hours. The strength and duration of the effects depend on the dose, the type of mushroom, and individual factors.
While the use of magic mushrooms has been associated with therapeutic benefits, such as treating chronic mental disorders like anxiety and depression, it is important to note that they are still illegal in many places. The sale, possession, and production of magic mushrooms are regulated and restricted in various countries, including Canada and the United States.
The evolutionary history of psilocybin in magic mushrooms is an intriguing area of research. Studies suggest that psilocybin first emerged in the genus Psilocybe around 65 million years ago, coinciding with a mass extinction event caused by an asteroid impact. The presence of psilocybin in other mushroom genera is believed to have resulted from horizontal gene transfers that occurred between 40 and 9 million years ago. The ecological shift from wood-decomposing to soil-dwelling habitats, as well as the transition to growing on herbivore dung, may have played a role in the evolution of psilocybin-producing mushrooms.
In conclusion, magic mushrooms, or psilocybin mushrooms, are hallucinogenic fungi that have been used for centuries in various cultural and therapeutic contexts. While they can induce a range of physical and psychological effects, the potential benefits and risks associated with their use are still being studied. The evolutionary history of psilocybin provides insights into the diversity and adaptations of these mushrooms, contributing to our understanding of their role in the natural world.

Therapeutic benefits
Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are hallucinogenic fungi that contain the prodrug psilocybin, which turns into the psychedelic compound psilocin upon ingestion. Psilocybin mushrooms have been used for hundreds or even thousands of years by Indigenous groups worldwide for healing, divination, and spiritual purposes.
Psilocybin mushrooms have been studied for their potential therapeutic benefits, particularly in the treatment of mental health disorders. Here are some of the key therapeutic benefits that have been observed:
- Depression and Anxiety: Psilocybin has been found to have antidepressant and anti-anxiety effects that can last for several months. It has been studied as a treatment for depression, including in people who are terminally ill, and has shown promising results. The active components of psilocybin mushrooms may help break old neural connections and create new ones, potentially reducing negative or obsessive thinking and improving overall mood and emotional responses.
- Post-Traumatic Stress Disorder (PTSD): Psilocybin mushrooms have been tested as a treatment for PTSD, with some positive outcomes. In Australia, from July 2023, medicines containing psilocybin can be prescribed by authorised psychiatrists to people experiencing treatment-resistant depression, as well as to individuals with PTSD.
- Substance Use Disorders: Psilocybin has shown therapeutic effects in people suffering from substance use disorders, including nicotine and alcohol dependence. It may help reduce cravings and promote positive behavioural changes.
- Existential Distress: Psilocybin mushrooms can help ease existential distress caused by life-threatening diseases. They have been found to produce experiences that result in substantial and sustained personal meaning, which can be beneficial for individuals facing mortality.
It is important to note that while psilocybin mushrooms have shown therapeutic potential, they also carry risks. They can cause unpleasant physical and psychological effects, such as nausea, vomiting, paranoia, and fear. Additionally, they may worsen the symptoms of certain conditions like personality disorders and schizophrenia. Therefore, it is crucial to approach the use of psilocybin mushrooms with caution and under the supervision of medical professionals in a controlled setting.

Spiritual and cultural uses
Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are hallucinogenic fungi that have been used for hundreds or thousands of years by Indigenous groups around the world. They are considered sacred in many cultures and have been used for healing, divination, spiritual rites, and religious ceremonies.
Psilocybin mushrooms have been used in Mexican and Central American cultures in religious, spiritual, and divinatory contexts. In Mesoamerica, the mushrooms have been consumed in spiritual and divinatory ceremonies for thousands of years. The Mixtec and Nahua cultures, including the Aztecs, are known to have used psilocybin mushrooms in their rituals, referring to them as "the flesh of the gods" or "divine mushrooms". The mushrooms were also depicted in pre-Columbian sculptures and glyphs throughout the Americas, indicating their cultural and spiritual significance.
Psilocybin mushrooms are believed to enhance self-awareness and a sense of connection with a "Transcendent Other," fostering a deeper understanding of our connectedness with nature. They are revered as powerful spiritual sacraments that provide access to sacred worlds. Typically used in small group community settings, they enhance group cohesion and reaffirm traditional values.
The use of psilocybin mushrooms can induce mystical experiences, characterized by intense spiritual and emotional responses. Users often report feelings of happiness, euphoria, and oneness with all life. These experiences can be influenced by the environment and the user's expectations, with potential adverse reactions such as nausea and panic attacks.
In addition to their spiritual and cultural uses, psilocybin mushrooms have been studied for their potential therapeutic benefits. They have been tested as a treatment for mental health disorders such as anxiety, depression, addiction, and post-traumatic stress disorder (PTSD). The active components of psilocybin mushrooms may have the ability to break old neural connections and create new ones, potentially reducing negative thought patterns and promoting positive behavioral changes.

Addiction and tolerance
Psilocybin mushrooms, also known as magic mushrooms or shrooms, are a type of hallucinogenic mushroom that contains the prodrug psilocybin, which turns into the psychedelic compound psilocin upon ingestion. Psilocybin and psilocin are responsible for the mind-altering effects of these mushrooms.
While psilocybin mushrooms have been used for thousands of years by Indigenous groups and in spiritual and religious contexts, they can still cause dependency and lead to addiction. Substance abuse disorder can open doors to various other mental health disorders, and individuals may need to undergo treatment in a rehabilitation facility to address their mushroom addiction and related mental health issues.
Tolerance to psilocybin mushrooms can develop with prolonged use, as the brain gets accustomed to functioning with mushrooms in the system. As a result, individuals may need to take higher doses of psilocybin mushrooms to feel the desired effects. This can be dangerous, as high doses of shrooms are more likely to lead to negative effects, such as "bad trips," which can resemble temporary psychosis.
Factors that affect psilocybin tolerance include age, weight, health, and genetics. In general, heavier, younger, and healthier individuals will have a higher shroom tolerance. Additionally, when shrooms stay in the body for longer periods, such as after taking a large dose, tolerance can increase even further.
Psilocybin mushrooms are not known to cause physical or psychological dependence, and the short-term nature of their effects can make them difficult to misuse. However, people can still become reliant on and abuse shrooms, increasing their tolerance and the likelihood of having a bad trip. Treatment options for psilocybin abuse include psychiatric interventions, behavioral therapy, and inpatient care.

Evolution and gene transfer
Psilocybin is a psychoactive natural product found in some mushrooms and other fungi. It was first synthesized in mushrooms in the genus Psilocybe, with four to five possible horizontal gene transfers to other mushrooms from 40 up to 9 million years ago. Psilocybin is at the forefront of a wave of recent research showing the potential of psychedelic drugs for a wide range of mental health therapies and for understanding human consciousness.
The evolution and ecology of psilocybin in nature suggest selective pressures that have led to the psilocybin phenotype. The high allocation of nitrogen to psiloids in mushrooms, along with evidence of convergent evolution and horizontal transfer of psilocybin genes, indicate potential fitness advantages of psilocybin production. The molecular structure of psilocybin mimics serotonin and binds tightly to serotonin receptors, especially at 5-HT2A, a famous receptor onto which many psychedelic drugs bind.
The specific evolutionary trajectories and unique properties of psilocybin production suggest the existence of yet-to-be-described ecological relationships between psilocybin-producing fungi and animals. Evidence of selection for psilocybin can be found in the genome of species that produce it, such as gene clustering, horizontal gene transfer, and gene cluster order corresponding to a deep split in the genus.
The horizontal transfer of the gene cluster appears to have occurred in environments with lots of insects, such as animal manure and rotten wood. Psilocybin may have evolved to be hallucinogenic because it lowered the chances of the fungi getting eaten by insects. The ability of psilocybin to interfere with the mind has a clear evolutionary benefit for mushrooms growing in such environments.
