The effects of psilocybin, the naturally occurring psychedelic compound found in certain mushrooms, are not influenced by body mass or body mass index (BMI). This is because psilocybin is a neurochemical that emulates serotonin, and there is little variation in brain size and neurological systems between people of different weights. However, some people argue that weight does play a role, as the stomach must break down the mushrooms, and a person's weight may impact this process. Additionally, individual sensitivity, the species and strain of mushroom, and other variables such as tolerance and stomach contents can influence the effects of psilocybin. While the relationship between BMI and psilocybin response is not well understood, psilocybin-assisted therapy is gaining traction in psychiatry.

What You'll Learn
Psilocybin is a neurochemical
Psilocybin is a prodrug of psilocin, which is its pharmacologically active metabolite. Psilocybin is rapidly converted by the body into psilocin, which acts as a non-selective agonist of serotonin receptors. Serotonin 2A (5-HT2A) receptor agonism is responsible for the psychological effects of psychedelics, and psilocin is about 1.4 times more potent than psilocybin due to differences in molecular weight.
The effects of psilocybin include euphoria, changes in perception, a distorted sense of time, and spiritual experiences. It can also cause adverse reactions such as nausea and panic attacks. Psilocybin's effects on the prefrontal cortex can impair an individual's ability to gauge time intervals and synchronize to inter-beat intervals. Users may experience a sense of connection to others, nature, and the universe, or they may have a ""bad trip" accompanied by fear and other unpleasant feelings.
Psilocybin has been used for centuries in spiritual and divinatory ceremonies, particularly in Mesoamerica. In modern times, it has been studied for its therapeutic potential in treating psychiatric disorders such as depression, substance use disorders, obsessive-compulsive disorder, and cluster headaches. Psilocybin-assisted therapy is making a resurgence in psychiatry, and it is in late-stage clinical trials for treatment-resistant depression.
While the therapeutic benefits of psilocybin are being explored, it is important to note that possession of psilocybin-containing mushrooms has been outlawed in most countries due to its potential for harm. Psilocybin has been classified as a Schedule I controlled substance under the United Nations Convention on Psychotropic Substances. Despite this, there is growing interest in researching psilocybin and other psychedelics for their potential therapeutic applications.

Body weight-adjusted dosing is common
Body weight-adjusted dosing is a common practice in pharmacological research, and this has been the case for studies on psilocybin as well. Psilocybin is one of the active constituents of 'magic mushrooms' and is known to induce psychedelic experiences. However, the impact of body weight on the intensity of these experiences has been a subject of debate.
Several individuals have shared their experiences with consuming mushrooms, with some stating that body weight does not matter. They attribute the varying intensity of the trip to factors such as the potency of the mushrooms, individual sensitivity, and the presence of other substances like weed. In contrast, others have suggested that weight plays a role similar to alcohol, where a higher body weight requires a higher dose for the same effect.
Research articles have addressed this debate by investigating the relationship between body mass index (BMI), psychedelic experiences, and long-term psychological outcomes. One study, in particular, assessed whether BMI predicted characteristics of the acute experience and changes in well-being two weeks later. However, the results indicated that body weight-adjusted dosing did not significantly influence the effects of psilocybin. This conclusion is supported by additional research, which found no evidence that body weight affected the subjective effects of psilocybin across a wide range of body weights.
While body weight-adjusted dosing is a common practice in research, the absence of a significant relationship between BMI and the effects of psilocybin suggests that other factors may play a more critical role in determining the intensity of psychedelic experiences. Further studies are needed to comprehensively understand the relationship between body weight and dosing, especially considering the financial and practical constraints imposed by weight-adjusted dosing on the scalability of psychedelic therapy.

Psilocybin emulates serotonin
Psilocybin is a naturally occurring psychedelic alkaloid found in over 200 species of mushrooms. It is also known as 4-phosphoryloxy-N,N-dimethyltryptamine (4-PO-DMT) and has hallucinogenic and serotonergic effects. Psilocybin is rapidly dephosphorylated to psilocin (4-hydroxy-N,N-dimethytryptamine), which is chemically related to serotonin and acts as a non-selective agonist of serotonin receptors.
Psilocybin's effects on the brain are not dependent on body weight or body mass index (BMI). This is because psilocybin is a neurochemical that emulates serotonin, and there is little variation in brain size and neurological systems based on weight. Therefore, the concentration of neuromass is relatively similar between people of different weights. While 5-HT2A receptor density has been linked to BMI, the impact of this on psilocybin's effects is unclear.
The psychedelic effects of psilocybin are believed to be caused by the stimulation of serotonin 2A receptors (5-HT2ARs) by psilocin. Studies have shown a correlation between the intensity of psychedelic effects and cerebral 5-HT2AR occupancy and plasma psilocin levels. Psilocybin has been found to increase mindfulness and produce substantial decreases in depression and anxiety in patients with life-threatening cancer. It has also been studied for the treatment of Alzheimer's disease and other mental disorders.
However, psilocybin use may also lead to adverse effects such as "bad trips" or panic reactions, characterised by anxiety, confusion, agitation, or disorientation. It can also cause transient increases in heart rate and blood pressure, and repeated use may lead to cardiac fibrosis and valvulopathy due to serotonin 5-HT2B receptor activation. Additionally, psilocybin has the potential to interact with other drugs, especially alcohol, increasing the risk of adverse events. Therefore, it is important to approach psilocybin with caution and be aware of potential risks and contraindications.

Individual sensitivity varies
While some people believe that body weight matters when it comes to the effects of psilocybin mushrooms, this is not the case. Psilocybin is a serotonin type 2A (5-HT2A) receptor agonist, and serotonin 2A receptor agonism is responsible for the psychological effects of psychedelics. The brain weighs roughly the same in all people, and there is not much difference in neurological systems depending on weight, so concentration in neuromass is similar across people of varying weights.
Body mass index (BMI) also does not seem to predict responses to psilocybin. While 5-HT2A receptor density has been linked to BMI, the impact of this on psilocybin therapy has not been explored. In a study where participants received a 25 mg dose of psilocybin, the results showed that the overall intensity of the psychedelic experience was not affected by differences in BMI.
However, individual sensitivity varies. Some people are hyper-sensitive and may experience a strong trip with a lower dose, while others may find that a higher dose is needed to achieve the same effects. The potency of the mushrooms, the species and strain, and individual brain chemistry all play a role in the effects felt. It is always recommended to start with a smaller dose and work your way up, as once the mushrooms are consumed, there is no going back.
Additionally, while BMI may not directly impact the effects of psilocybin, it can influence the dosing. Body weight-adjusted dosing is considered the "gold standard" in pharmacological research and has been used in some studies on psilocybin. However, this practice imposes financial and practical constraints on the scalability of psychedelic therapy.

The impact of BMI on psilocybin therapy is unclear
The impact of body mass index (BMI) on psilocybin therapy is unclear. While some evidence suggests that BMI does not affect the outcome of psilocybin-assisted therapy, there are still conflicting findings and a lack of comprehensive research on the relationship between BMI and the acute psychedelic experience.
Psilocybin is a naturally occurring psychedelic compound found in certain mushrooms, commonly known as "magic mushrooms." It has gained attention for its potential therapeutic benefits, particularly in psychiatry. Psilocybin acts as a serotonin type 2A (5-HT2A) receptor agonist, influencing serotonin receptors in the brain, primarily in the prefrontal cortex region. This interaction results in reduced energy requirements for the brain to transition between different activity states.
The impact of BMI on psilocybin's effects has been a subject of interest. A study by Meg J. Spriggs and colleagues, published in the Journal of Psychopharmacology, explored this relationship. They found that differences in BMI did not predict the overall intensity of the psychedelic experience or emotional breakthroughs. Additionally, when considering well-being, lower BMI was weakly associated with a greater "dread of ego dissolution," but this link disappeared when accounting for age and sex. These findings suggest that BMI may not be a significant factor in the context of psilocybin-assisted therapy.
However, it is important to acknowledge that the understanding of BMI's role is still evolving. Some sources indicate that 5-HT2A receptor density, which is associated with psilocybin's effects, may be linked to BMI. Additionally, body weight-adjusted dosing is a common practice in pharmacological research, including studies involving psilocybin. This approach, however, presents challenges for the scalability of psychedelic therapy in terms of practicality and cost.
The conflicting evidence and limited number of studies specifically examining the BMI-psilocybin relationship contribute to the uncertainty. While initial findings suggest that BMI may not be a critical factor, more comprehensive research is needed to definitively determine the impact of BMI on psilocybin therapy.
