Magic Mushrooms: Brain Chemistry And Hallucinations

how do hallucinogenic mushrooms affect the brain

Hallucinogenic mushrooms, commonly known as 'magic mushrooms', have been used for thousands of years. They contain the hallucinogenic substances psilocybin and psilocin and have a wide range of effects on the brain, including visual and auditory hallucinations, an altered state of consciousness, and changes in sensory perception and thought patterns. The effects of magic mushrooms vary from person to person and can be influenced by factors such as dosage, individual expectations, and the environment in which they are consumed. While the risk of addiction is considered low, there are potential dangers associated with their use, including the possibility of a 'bad trip' characterised by paranoia, anxiety, and fear. Despite these risks, there is increasing interest in the therapeutic potential of magic mushrooms, particularly in the treatment of mental health disorders.

Hallucinogenic effects

Hallucinogenic mushrooms, commonly known as "magic mushrooms", contain the hallucinogens psilocybin and psilocin. Psilocybin is converted by the body into psilocin, which is the chemical with psychoactive properties. These mushrooms have been used for thousands of years, with evidence of their use by indigenous people in Central America for healing and spiritual rituals as far back as 3000 BC.

The hallucinogenic effects of psilocybin usually occur within 15 to 45 minutes of ingestion and can last between four and six hours. The effects can vary from person to person and depend on factors such as the dose, type of mushroom, and individual expectations and past experiences. Some people may experience perceptual changes, such as visual and auditory hallucinations, and distortions in their sense of reality. They may see or hear things that are not there, or their senses may become mixed up, leading them to believe they can see music or hear colours.

Psilocybin works by binding to and activating serotonin receptors, particularly the 5-HT2A serotonin receptor, in parts of the brain that affect mood, cognition, and perception. These altered patterns of brain activity contribute to a person's profound change in consciousness, with some regions increasing in activity and connectedness while others decrease. This disruption in brain connectivity may be why some people experience a distorted sense of self and a loss of boundaries during a "bad trip".

While the risk of a bad trip is increased by higher doses or feelings of anxiety before taking psilocybin, it can be reduced by being in a good state of mind, with trusted friends, and in a safe, calm, and familiar environment. It is important to note that the production, sale, and possession of magic mushrooms are illegal in some places, and there are risks associated with misidentifying mushrooms and consuming poisonous ones.

Brain activity

The active ingredients in magic mushrooms are the hallucinogens psilocybin and psilocin. Psilocybin is converted by the body into psilocin, which is the chemical with psychoactive properties.

Psilocybin and psilocin work by binding to and activating serotonin receptors in parts of the brain, such as the prefrontal cortex and amygdala. These parts of the brain affect mood, cognition, and perception. Hallucinogens also work in other regions of the brain that regulate arousal and panic responses.

Psilocybin appears to decrease brain "connectivity" as measured by pharmaco-physiological interaction. It diminishes activity in key brain regions and networks implicated in hallucinogen actions. These findings challenge long-held models that hallucinogens enhance excitatory neurotransmission and overall brain activity.

The hallucinogenic effects of psilocybin usually occur within 15-30 minutes of ingestion and can last between four and six hours. In some people, changes in sensory perception and thought patterns can last longer.

The effects of magic mushrooms vary from person to person, and can be influenced by the user's mood, previous encounters with psychedelic drugs, expectations, and environment.

Serotonin receptors

Magic mushrooms, or mushrooms that contain hallucinogens, usually consist of psilocybin and psilocin. When psilocybin is ingested, it is converted into psilocin in the body. Psilocybin and psilocin are both classified as psychedelics or hallucinogens, which can alter a person's sense of reality and cause hallucinations.

Psilocybin and psilocin are known to affect the brain by binding to and activating serotonin receptors, specifically the serotonin 5-hydroxytryptamine 2A (5HT2a) receptor. Serotonin is a neurotransmitter that affects mood, cognition, and perception. The 5HT2a receptor is found on pyramidal glutamatergic neurons and GABA-ergic interneurons, and activation of these receptors can augment either excitatory or inhibitory neuronal activity. The activation of these serotonin receptors affects how the brain works and how different brain regions communicate with each other. These altered patterns of brain activity contribute to a person's profound change in consciousness, with some regions increasing in activity and connectedness while others decrease.

Research has shown that psilocybin decreases surrogate markers for neuronal activity in key brain regions implicated in psychedelic drug actions. Specifically, psilocybin appears to decrease brain "connectivity" as measured by pharmaco-physiological interaction. These findings challenge long-held models that hallucinogens enhance excitatory neurotransmission and overall brain activity.

The effects of magic mushrooms vary from person to person and can be influenced by factors such as dosage, past experiences, expectations, and the environment in which they are consumed. The effects usually begin within 15-45 minutes and can last between four to six hours. However, changes in sensory perception and thought patterns may last longer.

While magic mushrooms are not considered highly addictive, they can induce adverse side effects such as disturbing hallucinations, anxiety, paranoia, fear, nausea, and muscle twitches. In some cases, individuals may experience a "'bad trip'", which can be frightening and lead to risk-taking behaviour, traumatic injuries, or even death. It is important to note that the production, sale, and possession of magic mushrooms are illegal in some countries.

Safety and legality

The safety and legality of hallucinogenic mushrooms are complex issues that require careful consideration. From a safety perspective, it is essential to understand that hallucinogenic mushrooms can significantly impact an individual's perception of reality and judgment. As a result, engaging in activities that require concentration and coordination, such as driving, while under the influence of these mushrooms, can lead to accidents. Additionally, the effects of hallucinogenic mushrooms can be unpredictable and vary from person to person. Some people may experience feelings of euphoria and sensory distortion, while others may encounter disturbing hallucinations, anxiety, paranoia, and short-term psychosis. It is also important to note that the mushrooms themselves can be poisonous, and misidentification can lead to severe illness or even death. Furthermore, combining mushroom consumption with other substances, such as alcohol or other drugs, can increase the psychological and physical risks associated with their use.

In terms of legality, the status of hallucinogenic mushrooms, often referred to as "magic mushrooms" or "shrooms," varies across different jurisdictions. In the United States, for example, psilocybin mushrooms are classified as a Schedule I substance by the Drug Enforcement Administration (DEA), indicating a high potential for abuse and no accepted medical use. As a result, possession, sale, or distribution of these mushrooms is illegal and can carry significant legal penalties. However, there is a growing movement to decriminalize or legalize psilocybin mushrooms for therapeutic use, with several cities and states in the U.S. leading the way. For instance, cities like Denver, Oakland, Santa Cruz, and Ann Arbor have decriminalized the possession of psilocybin mushrooms, allowing residents to possess small amounts for personal use without facing criminal charges. Meanwhile, Oregon has gone a step further by establishing a legal framework for the therapeutic use of psilocybin.

Outside of the United States, the legality of hallucinogenic mushrooms varies by country and region. Some countries may have more lenient approaches to their possession and use, while others may have stricter regulations in place. It is crucial for individuals to be aware of the legal status of hallucinogenic mushrooms in their specific location to avoid potential legal consequences.

It is worth noting that, despite the illegal status of psilocybin mushrooms in many places, there is ongoing research into their potential therapeutic benefits. Some studies suggest that psilocybin may be effective in treating mental health conditions such as depression, anxiety, and obsessive-compulsive disorder (OCD). Additionally, psilocybin has been explored for its potential in helping individuals with cancer-related mental health issues. However, it is important to emphasize that, as of now, none of these treatments have been approved by regulatory bodies such as the United States Food and Drug Administration (FDA).

In conclusion, while hallucinogenic mushrooms have a long history of use in various cultures and show potential for therapeutic benefits, they also carry safety risks and legal implications that individuals must carefully consider. It is essential to stay informed about the latest research, understand the legal status in your specific location, and prioritize responsible and informed decision-making when it comes to the use of hallucinogenic mushrooms.

Therapeutic uses

Hallucinogenic mushrooms contain psilocybin, a hallucinogenic chemical that, when ingested, can cause hallucinations and sensory distortions. Psilocybin binds to and activates serotonin receptors in parts of the brain that affect mood, cognition, and perception.

Despite the potential for negative experiences and side effects, psilocybin has shown promise in the therapeutic treatment of various mental health conditions. Here are some of its potential therapeutic uses:

Depression

Psilocybin has been found to be potentially effective in treating depression, including treatment-resistant major depressive disorder, which often does not respond to traditional antidepressants. It is believed to help regulate the brain's reward system and disrupt negative thought patterns associated with depression, providing a new avenue for treatment. Research has shown that psilocybin can increase brain connectivity and flexibility in people with depression, even weeks after ingestion.

Anxiety

Psilocybin may also be useful in treating anxiety, including end-stage cancer-related anxiety. It can disrupt the negative, anxious thought patterns that characterize anxiety and increase brain connectivity in affected regions.

Post-Traumatic Stress Disorder (PTSD)

Psilocybin-induced psychedelic experiences can lead to profound changes in an individual's perception of self and their response to triggers, which may be beneficial in treating PTSD.

Substance Abuse

Psilocybin has shown potential in combating various forms of substance abuse. By disrupting rigid thought patterns and increasing brain flexibility, it may help individuals break free from the cycle of addiction.

Other Conditions

Preliminary research suggests that psilocybin may be beneficial in treating other conditions such as cluster headaches, anorexia, obsessive-compulsive disorder, and certain types of pain. However, more research is needed to understand the full therapeutic potential of hallucinogenic mushrooms.
