Hair follicle tests are considered highly reliable for long-term drug use assessment. However, there are misconceptions about whether these tests can detect psychedelic mushrooms. Standard drug tests do not typically test for psilocybin, the compound found in magic mushrooms. However, there are specialized hair tests that can detect psilocin, the metabolite produced when the body breaks down psilocybin. These tests can detect psilocin in hair follicles for up to 90 days after use, but they are more costly and less common than other drug tests.

Hair follicle tests can detect drug metabolites for up to 90 days
Hair follicle tests are a common method of drug testing. Once a drug enters the bloodstream, it travels throughout the body, and as it is broken down, drug metabolites enter the hair through the hair follicle, sweat glands, and oil glands on the scalp. These drug metabolites remain in the hair as it grows, at a rate of about half an inch per month. Some metabolites attach to melanin, the part of the hair follicle that gives hair its colour. Hair follicle testing has a longer window of detection than other types of drug tests, typically around 90 days, but this can vary depending on the drug, the dose, the sensitivity of the test, and the matrix that is analysed.
The window of detection also depends on the amount of hair tested. A standard sample of hair from the scalp is 1.5 inches and provides information about approximately 90 days of past drug exposure. This is because head hair grows at an average of about half an inch per month. Longer samples of hair can be tested for drug exposure over a longer period, and hair samples taken from other parts of the body where hair grows more slowly may have a detection window of up to 12 months.
Hair follicle tests can detect a range of drugs, including marijuana, amphetamines, cocaine, PCP, and opioids. The tests can determine patterns of illicit drug use or prescription medication misuse over a certain period, typically up to three months for hair samples from the head. While hair follicle tests can identify regular, long-term drug use, they cannot detect current intoxication.
There is a specialised hair follicle test for Psilocin, the compound created by the body's breakdown of Psilocybin, which is found in magic mushrooms. However, this test is not standard, and most drug panels do not include Psilocybin. Interpretation of hair tests for Psilocin is difficult, and there are limitations to the testing method.

Psilocybin mushrooms are rarely included in standard drug screening panels
Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are not typically included in standard drug screening panels. While hair follicle testing can be used to detect these substances, it is not a common practice.
Standard drug tests typically screen for substances such as THC, cocaine, opiates, benzodiazepines, amphetamines, and opioids. These panels may range from 5 to 12 panels, but they do not routinely include psilocybin or psilocin, the active compounds in magic mushrooms. The absence of psilocybin from standard panels is likely due to the rapid metabolization of psilocybin into psilocin and the subsequent excretion of psilocin from the body within a relatively short time frame.
However, it is important to note that specialized tests can detect psilocybin and psilocin in hair follicles, urine, saliva, or blood. These specialized tests are designed specifically to identify psilocin, the metabolite of psilocybin. The detection window for these substances is relatively short, with psilocin typically excreted from the body within 3.5 hours and psilocybin within 6 hours. After 24 hours, the compounds are no longer detectable in urine.
Hair testing can provide a longer detection window, with each 1 cm of hair representing one month of drug misuse. However, hair sample preparation and interpretation are complex and require specialized techniques such as Liquid Chromatography coupled to Mass Spectrometry (LC-MS/MS). The interpretation of hair tests for psilocin is challenging due to its sensitivity to water, light, air, and temperature. Additionally, psilocybin was not observed in initial tests with authentic hair specimens, indicating that only psilocin may be identified in hair.
In conclusion, while psilocybin mushrooms can be detected in hair follicle tests, they are rarely included in standard drug screening panels due to the specialized nature of the tests and the short detection window for these substances.

Hair follicle tests are highly reliable for long-term drug use assessment
Hair follicle tests are widely used to assess long-term drug use and provide valuable insights into an individual's drug exposure history. This type of testing is favoured for its ability to detect drugs over an extended period, making it ideal for chronic drug use detection, understanding long-term patterns, and confirming periods of abstinence.
One key advantage of hair follicle testing is its longer window of detection compared to other drug tests. While drug traces may not appear in hair until 7 to 10 days after initial use, they can remain detectable for weeks, months, or even years. This feature makes hair follicle tests highly reliable for evaluating long-term drug use, as they provide a broader timeline of drug exposure.
The standard detection time for a head hair test is approximately 90 days. However, body hair, which has a longer growth cycle, can extend the detection window to 6-12 months. This variability allows for flexibility in testing, catering to different investigative needs. Additionally, hair testing can be segmented into 30-day intervals, offering a detailed month-by-month breakdown of drug use patterns.
Hair follicle tests are particularly useful in specific contexts, such as employment screening, forensic investigations, and drug rehabilitation programs. Employers may use these tests for pre-employment screening, random drug testing, or post-incident assessments. Forensic and legal professionals may employ hair follicle testing in criminal investigations and child protection cases. In drug rehabilitation, these tests help monitor chronic drug use, understand abstinence, and inform treatment plans.
While hair follicle tests offer advantages, it's important to acknowledge their limitations. Firstly, they cannot determine the amount or frequency of drug use, only providing an indication of use history. Secondly, external factors like hair treatments, colouring, and UV exposure can affect the concentration of drugs detected. Interpretation of results can be challenging due to the lack of standardised cutoff values, and certain drugs may be more easily detected in darker hair.

Interpretation of hair tests for psilocybin is difficult
Another challenge is the lability of psilocin, which requires that all analytical procedures be completed within a single working day. Additionally, psilocin is sensitive to water, light, air, and temperature, further complicating the interpretation of test results. Cold conditions during hair preparation and protection from light are crucial to avoid psilocin degradation.
The interpretation of hair tests for psilocin is further complicated by the limited and sometimes controversial data available. For example, Pichini et al. identified psilocybin in the hair of a Psilocybe consumer, while no psilocin was found, which contradicts other findings. Furthermore, there are various issues that require further research and discussion within the scientific community before definitive interpretations of positive or negative results can be made. These include distinguishing between passive exposure and active consumption, as well as determining the time, dosage, and frequency of use based on test results.
While hair tests can detect psilocin, the interpretation of these results is complex and requires specialized knowledge and techniques. The development of specific methods to identify psilocin in human hair is an ongoing area of research, and further advancements are needed to improve the accuracy and reliability of hair tests for psilocybin interpretation.

Standard drug tests do not test for psilocybin
Hair follicle testing, for example, can detect psilocybin for up to 90 days. However, these screenings are more costly and less common than urine tests. Hair testing can be performed on head hair or body hair, with head hair being segmented into different time frames, and body hair constantly growing and falling out at different rates. The standard detection time for head hair is approximately 90 days, while the standard detection time for body hair is approximately 6-12 months.
Psilocybin is rapidly metabolized into psilocin, which is the key analyte to document magic mushroom exposure. However, interpretation of hair tests for psilocin is very difficult. There are several issues that still require substantial research and discussion within the scientific community before a definitive interpretation of positive or negative results can be given.
Although standard drug tests do not test for psilocybin, specialized tests can detect the compound. These specialized tests may need to take place soon after ingestion, as psilocybin leaves the body relatively quickly.
