Subjective and Physical Effects of Psilocybin Mushrooms


Psilocybin mushrooms are known for inducing a variety of subjective and physical effects, some of which are unique to this psychedelic substance. This article provides an in-depth look at the effects of psilocybin, focusing on the headspace it induces, the various bodily sensations, and the physiological changes it can cause. It also covers potential therapeutic benefits and side effects that users may experience.

Subjective Effects


Headspace and Mental Effects


Psilocybin mushrooms are often described as inducing a relaxing, profound, and stoning headspace. The mental state produced by psilocybin is generally less stimulating than other psychedelics like LSD or 2C-B. The experience is usually characterized by a deep sense of calm and introspection, which contrasts with the more energetic or "clear-headed" states induced by other substances. Many users find themselves absorbed in introspective or spiritual thoughts, with some reporting a heightened sense of connection to their surroundings or the universe.


Comparisons with Other Psychedelics


Compared to other commonly used tryptamines like 4-AcO-DMT, DMT, and ayahuasca, psilocybin is typically seen as less clear-headed. The effect may be due to the presence of other alkaloids, such as norbaeocystin, which contribute to the unique quality of the psilocybin experience. This reduction in mental clarity may result in a more emotionally charged and physically grounded experience.



Physical Effects


The physical effects of psilocybin mushrooms are diverse and can be quite pronounced, ranging from intense bodily sensations to minor physiological changes. These effects can vary depending on the individual, the dose, and the setting of the experience.


Neurogenesis


Psilocybin has been shown to promote neurogenesis, or the growth of new neurons. This potential ability to stimulate brain cell growth may explain some of its therapeutic applications, particularly in the treatment of depression, anxiety, and PTSD. Research suggests that psilocybin’s ability to increase brain plasticity could lead to long-term positive changes in brain function.


Sedation


One of the most common physical effects is sedation. Psilocybin mushrooms are reported to have a relaxing, stoning, and mildly sedating effect. Users often feel physically and mentally at ease, and this sensation is frequently accompanied by excessive yawning, a hallmark of the experience.


Spontaneous Bodily Sensations


Many users report experiencing a body high characterized by a pleasurable, soft, and all-encompassing tingling sensation or a glow. This sensation builds up gradually, intensifying as the trip progresses, and reaches its peak at the height of the experience. Depending on the dosage, this sensation can feel euphoric and tranquil or, in some cases, heavy and immobilizing.


Perception of Bodily Heaviness


Along with the overall sense of sedation and relaxation, users may experience a bodily heaviness. This effect typically occurs during the earlier phases of the trip and discourages movement. The heaviness is often described as soothing, but can be somewhat immobilizing. This particular effect is more commonly reported in “woodlover” species of mushrooms, such as Psilocybe azurescens.


Tactile Enhancement


Psilocybin can lead to tactile enhancement, though this effect is less pronounced compared to other psychedelics such as LSD or 2C-B. When present, tactile enhancement often feels primitive in nature, with users reporting sensations like slight itchiness or ticklishness in the small hairs of their arms or legs. The heightened sensitivity to touch can feel both strange and pleasant.


Changes in Felt Bodily Form


Around the peak of the psilocybin experience, users often report changes in their perceived bodily form. This can involve a sensation of unity or merging with surrounding objects, contributing to a sense of warmth and connectedness. These experiences are typically described as peaceful and comfortable, and they contribute to the overall feeling of oneness that is characteristic of the psilocybin experience.


Pain Relief


Psilocybin may offer some degree of pain relief, though it is generally less intense compared to other psychedelics like LSD. This effect is thought to be due to reductions in inflammation and distortions in sensory perception. While pain relief is a common effect, it is not guaranteed and, in some cases, users may experience an increase in pain perception rather than relief.


Nausea


Nausea is a common physical side effect of psilocybin, especially during the onset of the experience. However, it can be reduced or avoided by ensuring that the stomach is empty before ingestion. It is often recommended that individuals fast for 6 to 8 hours prior to consuming psilocybin or have a light meal 3 to 4 hours before ingestion if they are feeling physically fatigued.


Changes in Felt Gravity


Users may also experience changes in their perception of gravity. This can lead to sensations of lightness or heaviness, depending on the individual’s mindset and environment. The altered sense of gravity can contribute to feelings of floating or feeling “anchored” to the ground.


Excessive Yawning and Watery Eyes


Excessive yawning and watery eyes are distinctive effects often reported with psilocybin use. Yawning is notably more common with psilocybin and related tryptamines compared to other psychedelics, like LSD. This effect typically occurs alongside watery eyes and is part of the overall sedative and relaxing experience.



Other Physical Effects


While not as commonly discussed, psilocybin mushrooms can cause a variety of other physical effects, including:


  • Frequent urination: Users may find themselves needing to urinate more frequently during the experience.
  • Muscle contractions: Some individuals may experience muscle spasms or contractions, particularly in the limbs.
  • Olfactory hallucinations: Though rare, some users report experiencing smells that are not actually present during the trip.
  • Pupil dilation: Like most psychedelics, psilocybin causes noticeable pupil dilation, which can lead to visual distortions and sensitivity to light.
  • Runny nose: A runny nose can occur during a psilocybin trip, though it is not a universal effect.
  • Increased salivation: Increased saliva production can cause a sensation of excessive moisture in the mouth, contributing to slight discomfort.
  • Brain zaps: A rare phenomenon, brain zaps are described as sudden, sharp sensations in the head, though they are much less common and intense than those associated with serotonin-releasing drugs like MDMA.
  • Seizures: Though extremely rare, some individuals predisposed to seizures may experience them during psilocybin trips, especially in physically taxing conditions such as dehydration, exhaustion, or being overheated.



In conclusion, the effects of psilocybin mushrooms are complex and multifaceted, involving a combination of mental, emotional, and physical changes. While many of these effects are beneficial or neutral, they can also present challenges for those unprepared for the intensity of the experience. Psilocybin remains a substance with potential therapeutic benefits, but like any psychedelic, it should be approached with care and respect.
