While there is no definitive proof that ingesting mushrooms can change human DNA, some studies have shown that psychedelics can alter brain network connectivity and influence gene expression changes. For example, psilocybin, the active compound in magic mushrooms, has been shown to improve depressive, anxiolytic, and addictive symptoms in patients. Additionally, LSD has been found to induce rewiring of gene co-expression networks in rats, with prolonged exposure leading to long-term effects on epigenetic machinery. Furthermore, certain alkaloids like caffeine can intercalate DNA, altering the way genes are expressed structurally. However, these changes do not affect the sequence of nucleotides but rather the accessibility of polymerase enzymes to various genes. While it is known that mushrooms share approximately 50% of their DNA with humans, there is limited evidence to suggest that ingesting mushrooms can directly change human DNA.

Magic mushrooms contain psilocybin, which quickly turns into psilocin after ingestion
While there is no definitive proof that ingesting mushrooms can change human DNA, there is evidence that experiences can alter DNA. It is also known that certain alkaloids like caffeine can intercalate DNA, changing the way it is packed or coiled, and affecting the expression of genes.
Magic mushrooms contain psilocybin, a prodrug that turns into psilocin after ingestion. Psilocybin is the key ingredient in magic mushrooms, and it is this substance that is converted in the body to psilocin, the chemical with psychoactive properties. Psilocybin is found in specific fungi such as psilocybe cubensis, the most popular species. Psilocybin levels appear to be highest in P. cyanescens and/or P. azurescens.
Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are a polyphyletic informal group of fungi that contain psilocybin. They are hallucinogenic and have been used for thousands of years, including in religious rituals. The use of magic mushrooms rarely results in life-threatening symptoms, but negative effects can include a 'bad trip', delayed headaches, and flashbacks.
Psilocybin is converted by the body into psilocin, which is chemically near-identical to serotonin. Psilocin attaches to and activates serotonin receptors, primarily the 5-hydroxytryptamine 2A (5HT2a) receptor. This activation affects how the brain works and how brain regions communicate with each other, resulting in altered patterns of brain activity and a profound change in consciousness. Some regions increase in activity and connectedness while others decrease.
The dosage of psilocybin-containing mushrooms depends on the psilocybin and psilocin content, which varies significantly between and within species. Recreational doses of psilocybin mushrooms are typically between 1.0 and 3.5–5.0 g of dry mushrooms and 10 to 50 g of fresh mushrooms.

Psilocin is chemically near-identical to serotonin
While there is no definitive proof that ingesting mushrooms can change one's DNA, there is speculation that it can alter it epigenetically. Some studies have shown that certain compounds can intercalate DNA, affecting how it is packed or coiled, but not the sequence of nucleotides.
Psilocybin, the main active agent in "magic mushrooms", is rapidly converted by the body into psilocin, which is chemically near-identical to serotonin. Psilocybin was first isolated from Psilocybe mexicana, a mushroom from Central America, by Albert Hofmann in 1957, and then produced synthetically in 1958. Psilocybin is a prodrug, which means it is biologically inactive until it is converted into psilocin by dephosphorylation. This process can occur in a variety of tissues, but high activity has been observed in the kidneys and livers of rodents, as well as in human plasma.
Psilocin is a close analogue of serotonin, a monoamine neurotransmitter, and acts as a non-selective agonist of serotonin receptors, including the serotonin 5-HT2A receptor, which is responsible for the hallucinogenic effects of psilocin and other serotonergic psychedelics. Psilocin exhibits functional selectivity, activating phospholipase A2 instead of phospholipase C, as serotonin does. It also has a higher affinity for the serotonin 5-HT2A receptor in humans than in rats due to species differences.
The structural similarity between psilocin and serotonin allows psilocin to stimulate serotonin receptors in the CNS, producing physiological effects. Activation of the 5-HT2A receptor leads to increased cortical activity, while activation of the 5-HT1A receptor results in the inhibition of pyramidal cell activity. Psilocin may also have peripheral effects involving serotonergic receptors, such as increased heart rate, blood pressure, and body temperature. These effects are similar to those produced by LSD and are observed within 20-30 minutes of ingestion.

Psilocybin has been shown to improve depressive, anxiolytic, and addictive symptoms
Psilocybin, a compound found in "magic mushrooms", has been shown to improve depressive, anxiolytic, and addictive symptoms. Research has demonstrated that psilocybin produces perceptual changes, altering a person's awareness of their surroundings, thoughts, and feelings.
In a study conducted by Johns Hopkins Medicine researchers, psilocybin-assisted therapy, when combined with supportive psychotherapy, provided substantial relief from major depressive disorder symptoms in adults for up to a year. The treatment produced large decreases in depression, and the severity remained low even after one year. The average pretreatment score of 22.8 decreased to 8.7 at one week, 8.9 at four weeks, 9.3 at three months, 7 at six months, and 7.7 at 12 months.
Another study recruited 27 participants with a long-term history of depression, with most experiencing symptoms for about two years. The results showed an 88% response rate and a 58% remission at 12 months. These findings suggest that psilocybin may be a uniquely useful treatment for depression due to its immediate effects and long duration.
The therapeutic potential of psilocybin is attributed to its ability to induce brain neuroplasticity and increase BDNF levels. BDNF (Brain-Derived Neurotrophic Factor) is involved in neuroplasticity processes such as synaptic modulation, adult neurogenesis, and dendritic growth. By enhancing these processes, psilocybin helps alleviate depressive, anxiolytic, and addictive symptoms.
While psilocybin has shown promising results in treating depressive and anxiolytic symptoms, it is important to note that the understanding of its mechanism is still evolving. Some researchers suggest that the 5-HT2A receptor, while crucial for the hallucinatory effects of psychedelics, may not be solely responsible for their antidepressant effects. Further research is needed to fully comprehend the complex interactions between psilocybin and the brain.

A 2021 study showed LSD-induced rewiring of gene co-expression networks in rats
While there is no definitive proof that ingesting mushrooms can change one's DNA, there is ongoing research into the effects of psychedelics on human DNA. A 2021 study by Charles Nichols showed that LSD induces rewiring of gene co-expression networks in rats. The study analysed RNA-seq data and found that genes related to neuroplasticity and transmission were upregulated, including BDNF. The data also revealed that prolonged LSD exposure has long-term effects on epigenetic machinery, with certain genes highly enriched. These genes are involved in processes such as "covalent chromatin modification" and "histone modification". Computational analysis was used to construct gene-coexpression networks, allowing researchers to investigate regulatory relationships between genes before and after LSD treatment. This study adds to the growing interest in the therapeutic potential of psychedelics for treating psychiatric conditions.
The 2021 study by Nichols builds upon previous research that has explored the impact of psychedelics on gene expression. For instance, a 1993 study observed increased c-Fos expression in the brains of rats following DOI administration, and this change was mediated via the 5-HT2A receptor. Subsequent studies reaffirmed these findings and demonstrated a dose-response relationship. Furthermore, LSD was found to induce c-Fos expression and increase mRNA levels in rats, similar to the effects of DOI. These discoveries highlight the complex interactions between psychedelics and gene expression.
The 5-HT2A receptor has been identified as a critical target for psychedelics, and it plays a role in their hallucinatory effects. However, the 5-HT2A receptor may not be solely responsible for the antidepressant effects of these drugs. The serotonin (5-HT2A) receptor is the key receptor that psychedelics bind to, and psilocin, the active compound in "magic mushrooms," is chemically similar to serotonin. Gene variants coding for different variants of this receptor have been identified, and they may influence the potency of psychedelics.
While the 2021 study by Nichols provides valuable insights into the effects of LSD on gene expression in rats, it is important to note that the interpretation of RNA-seq data can be complex. Single-cell RNA-seq experiments and additional time-course studies are needed to fully understand the dynamics of gene expression responses to LSD. Furthermore, the indirect activation of neuronal cell types by LSD has been observed, but the specific responses of different cell populations remain to be elucidated.
In conclusion, the 2021 study by Charles Nichols contributes to our understanding of the molecular mechanisms underlying the effects of psychedelics. While the study focused on LSD-induced rewiring of gene co-expression networks in rats, further research is needed to translate these findings to human subjects. The therapeutic potential of psychedelics in psychiatry is an emerging field, and ongoing studies aim to clarify the role of gene expression and DNA interactions in the complex responses to these drugs.

Experiences can alter our DNA, so it's speculated that the psychedelic experience can alter DNA
While there is no definitive proof that ingesting mushrooms or other psychedelics can change human DNA, there is ongoing research into the effects of these substances on gene expression and brain network connectivity. Some studies have shown that psychedelics like LSD, ayahuasca, and psilocybin, found in "magic mushrooms", can have positive effects on depressive, anxiolytic, and addictive symptoms in patients, with the effects lasting several weeks to almost 6 months after just one or two doses.
The active metabolite in magic mushrooms, psilocin, is chemically near-identical to serotonin and binds to the 5-HT2A receptor in the brain, which is responsible for the hallucinogenic effects of these substances. Research has shown that psilocybin can significantly alter brain network connectivity, facilitating hyperconnectivity between brain regions that do not usually communicate. These changes in molecular processes can influence gene expression and synaptic plasticity, potentially leading to more long-term changes in brain neurochemistry.
A 2021 RNA-seq study by Charles Nichols found that LSD induced the rewiring of gene co-expression networks in rats. The analysis showed that genes related to neuroplasticity and transmission were upregulated, and that prolonged LSD exposure had a long-term effect on epigenetic machinery. However, it is important to note that these studies were conducted on rats, and the effects of LSD on human DNA may differ.
While there is no direct evidence that ingesting mushrooms can change human DNA, some people speculate that the psychedelic experience can alter DNA in a similar way to how experiences can lead to epigenetic changes in gene expression. Caffeine, for example, is known to intercalate DNA, affecting how it is packed or coiled without changing the sequence of nucleotides. These structural alterations can impact which genes are expressed by affecting polymerase enzyme access. While psychedelics may have similar intercalating effects, there is currently no proof that they can epigenetically affect the human transcriptome.
