Psychedelics Tolerance: Lsd And Mushroom Cross-Tolerance

Mushrooms and LSD are two of the most well-known psychedelics, with both similarities and differences in the experiences they produce. While mushrooms tend to produce a more whole-body experience, an LSD trip is more cerebral. In addition, the duration of the trips varies, with mushroom trips usually lasting around 6 hours and LSD trips lasting up to 10 hours. Despite these differences, there is evidence to suggest that there is a cross-tolerance between the two substances. This means that repeated use of one substance may lead to a decrease in responsiveness to the other. Several studies have explored the development of direct and cross tolerance between LSD and psilocybin, the active compound in mushrooms, with varying results. While some individuals have reported experiencing cross-tolerance, others have claimed to have dosed back-to-back without noticing any tolerance issues.

Does LSD affect mushroom tolerance?

LSD and shrooms have a cross tolerance

LSD and shrooms (mushrooms) are the two most well-known psychedelics. While they have similarities, they can also produce very different experiences. Both substances can cause temporary physical and psychological complications, such as paranoia or fear, and have been associated with a rare condition called hallucinogen-persisting perception disorder (HPPD), which causes recurring hallucinations or "flashbacks" after the trip.

There is a consensus that combining mushrooms and LSD increases the intensity of each, which can be dangerous. Taking them together can also increase the risk of serotonin syndrome. It is recommended that, when experimenting with this combination, one should start with low doses of each substance and monitor their effects.

There is evidence of a "cross-tolerance" between LSD and psilocybin (the active compound in shrooms). In other words, if an individual is tolerant to LSD, they will also be tolerant to psilocybin, and vice versa. This was demonstrated in two experiments where patients who had developed a tolerance to LSD after receiving increasing doses over 6-7 or 13 days were then administered psilocybin. The patients displayed tolerance to psilocybin, and vice versa.

The development of cross-tolerance between LSD and psilocybin suggests that these two drugs may cause psychic disturbances by acting on some common mechanism. This is further supported by the fact that both LSD and psilocybin are serotonergic drugs, and their hallucinogenic properties are mediated by the serotonin 2A receptor (5-HT2AR).

Tolerance is a decrease in responsiveness to a drug

In the case of LSD and psilocybin ("magic mushrooms"), there is a high degree of "direct" tolerance to LSD, as shown by statistically significant reductions in six out of seven parameters of response in experiments. This means that with repeated use, individuals may need higher doses of LSD to achieve the same effects. On the other hand, the development of "direct" tolerance to psilocybin was less pronounced, with statistically significant reductions occurring in fewer parameters of response.

Cross-tolerance between LSD and psilocybin has also been observed. This means that individuals who are tolerant to LSD may also be tolerant to psilocybin, and vice versa. However, the degree of cross-tolerance may vary, and some individuals may still experience effects from both substances despite the development of tolerance.

It is important to note that while mushrooms and LSD have some similarities, they can produce very different experiences. Mushrooms tend to produce more of a whole-body experience, while an LSD trip is largely cerebral. Additionally, the onset time and duration of the trip differ between the two substances. Therefore, the specific effects and tolerance development may vary between individuals based on their unique physiological and psychological factors.

While LSD and mushrooms are not considered highly addictive substances, repeated use can lead to tolerance and potential psychological and physical complications. It is always important to approach these substances with caution and be aware of the potential risks involved.

The development of direct tolerance to LSD

LSD, or lysergic acid diethylamide, is a potent hallucinogenic drug that can cause altered perceptions, behaviours, and moods in humans. Repeated use of LSD can lead to psychological and physical consequences such as dependence and tolerance.

Tolerance is defined as a decrease in responsiveness to a drug after repeated administration. The development of "direct" tolerance to LSD was observed in two experiments using a cross-over design. In these experiments, 9-10 volunteers were given increasing doses of LSD over the course of 6-13 days. The volunteers developed a high degree of "direct" tolerance to LSD, as shown by significant reductions in their responses.

Direct tolerance to LSD was also observed in rats. In one study, rats were injected with LSD or saline daily for 5 days. The rats injected with LSD showed a significant reduction in their responsiveness to LSD, indicating the development of tolerance.

Cross-tolerance between LSD and psilocybin (magic mushrooms) has also been observed. Volunteers who were directly tolerant to LSD after chronic administration were also cross-tolerant to psilocybin. Similarly, those who developed direct tolerance to psilocybin were also cross-tolerant to LSD. This suggests that LSD and psilocybin may act through a common mechanism to produce their effects.

In summary, direct tolerance to LSD can develop after repeated administration, leading to a decrease in responsiveness to the drug. Cross-tolerance between LSD and psilocybin has also been observed, indicating that they may share some similarities in their mechanisms of action.

Cross tolerance to LSD and shrooms

LSD and shrooms (mushrooms) are two of the most well-known psychedelics. While they have similar effects, they can produce very different experiences. Mushrooms produce more of a whole-body experience, whereas an LSD trip is largely cerebral. An LSD trip can continue for up to 10 hours, while a mushroom trip usually ends within 6 hours.

Both substances present few major risks, but there are some potential physical and psychological complications to be aware of. There is a risk of an unpleasant trip involving paranoia or fear, and some people experience lingering distress. In rare cases, psychedelics have been associated with hallucinogen-persisting perception disorder (HPPD), where people experience recurring hallucinations or "flashbacks" long after a psychedelic experience. Combining mushrooms and LSD increases the intensity of each, which can also increase the risk for serotonin syndrome.

There is evidence of cross-tolerance between LSD and psilocybin, the active compound in psychedelic mushrooms. In one study, patients who had developed a high degree of "direct" tolerance to LSD after taking increasing doses over the course of 6-7 or 13 days were found to be "cross-tolerant" to psilocybin. Similarly, patients chronically treated with psilocybin were also found to be "cross-tolerant" to LSD.

Another study in mice found that repeated administration of the psychedelic 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) induced a progressive decrease in head twitch response (HTR) behavior, indicating the development of tolerance. Cross-tolerance became apparent between DOI and LSD, as well as between other psychedelics such as DOI, psilocybin, N,N-dimethyltryptamine (DMT), and LSD.

It is recommended to wait at least two weeks between taking LSD and mushrooms to allow for the tolerance to reset. However, some people have reported taking both substances within a few days and still experiencing the effects of both.

Cross tolerance is evaluated by challenging patients

Cross-tolerance occurs when developing a tolerance for one substance leads to tolerance of another. It is the process by which one drug reduces the body's sensitivity to another drug that acts on the same brain receptors. Cross-tolerance is evaluated by challenging patients with a new substance after they have received another chronically. For example, in one study, patients were administered LSD in increasing doses over the course of 6-7 days or 13 days. After this, the same patients were challenged with psilocybin, another psychedelic substance, in increasing doses over a similar period. The development of "cross" tolerance to psilocybin was then measured.

The concept of cross-tolerance is important in the medical field as it can complicate treatment plans for patients. For instance, a person with a high tolerance for alcohol may not respond effectively to sedatives or anti-anxiety medications. This makes treating mental health conditions more challenging as the central nervous system has adapted to the effects of both substances.

Incomplete cross-tolerance is when the effects of medications are diminished but not completely removed. On the other hand, complete cross-tolerance occurs when neither drug has any effect at its current dosage, which is the most severe form as it has the highest risk for dependence and addiction. Cross-tolerance can also lead to an increased risk of overdose.

To avoid cross-tolerance, it is recommended to look at the class of each substance being used. It is advised to avoid taking more than one substance from the same class unless suggested by a doctor.
