Psychedelic Mushrooms: Do They Show On Drug Tests?

Psychoactive mushrooms, also known as magic mushrooms or shrooms, do not show up on standard drug tests such as 5, 8, 10, or 12-panel urine tests. These tests typically screen for more commonly abused substances like THC, cocaine, amphetamines, opioids, and PCP. However, specialized tests designed specifically to detect psilocybin or its metabolite psilocin in urine, saliva, blood, or hair follicles can identify mushroom use. The detection window for these specialized tests varies depending on the testing method and the individual's metabolism, with urine tests detecting mushroom use for up to 24 hours and blood tests for up to 12 hours. While less common, hair tests can detect mushroom use for up to 90 days after consumption.

Standard urine tests

Standard drug tests primarily screen for more commonly abused substances, such as THC (marijuana), cocaine, amphetamines, opiates, and PCP. For example, the 5-panel urine test, which is commonly used by employers and in clinical settings, does not include the ability to detect psilocybin or psilocin. These compounds are also not included in the more comprehensive 10-panel test, which is usually reserved for specific situations, such as in forensic or legal settings.

While standard urine tests do not screen for psilocybin or psilocin, specialised tests can detect their presence. These tests are less commonly administered and often reserved for specific situations. For example, in legal scenarios, such as child custody disputes or public intoxication cases, a court-ordered test might be requested to detect psilocybin or psilocin in urine samples. However, due to the short detection window of these compounds in urine, typically no more than 24 hours after consumption, such testing must be performed as soon as possible.

It is important to note that false positives for psilocybin are rare but can occur, particularly with less specific tests, due to potential cross-reactivity with other substances. Additionally, the detection window for psilocybin and psilocin in urine can vary depending on individual factors, such as body weight, metabolism, and frequency of mushroom use.

Specialised urine tests

Standard urine tests do not screen for psilocybin or psilocin, the active compounds in psychoactive mushrooms. However, specialised urine tests can detect these substances. These specialised tests are rarely administered due to their high cost and the short detection window. Urine tests can detect shrooms in your system for up to 24 hours after the last use, and the results are usually available within a day. The detection window may be extended to 1-3 days in the case of a chronic user, but this is rare.

The detection window for psychoactive mushrooms in urine tests is shorter than that of hair or fingernail tests, which can detect psilocybin for up to 90 days and six months, respectively. However, these tests are even less common than specialised urine tests due to their higher cost and more specialised nature.

While standard urine tests do not typically detect shrooms, they may show up on standard tests if the mushrooms are contaminated with other drugs. There have been reports of mushrooms being laced with other drugs, including PCP, which is detected by most standard panel tests.

Blood tests

Psilocybin, the psychedelic compound in mushrooms, is not psychoactive. Instead, it is a prodrug that the body converts into psilocin, the compound responsible for the hallucinogenic effects. Psilocybin is rapidly metabolized into psilocin, which is then cleared from the body within hours. This rapid elimination makes it difficult to detect unless testing occurs soon after ingestion. The half-life of psilocin has been estimated to be 3 hours, which means it takes about 15 hours for it to be completely eliminated from the body.

Standardized drug tests don't test for psilocybin or psilocin. A standard 5-panel drug test detects popular drugs of abuse, such as cocaine, marijuana, and opioids. Nine-panel tests include additional drugs, such as benzodiazepines and barbiturates. Magic mushrooms aren't included in either panel. It's unclear how long blood tests can detect psilocybin or psilocin, but since psilocybin almost completely leaves a person's blood after 13 hours, it's unlikely that a blood test will detect the drug after one day. Blood tests are not commonly used to detect shrooms because they provide a shorter window of detection, even when using a specialized panel. With that being said, blood tests can find psilocin in your system for up to 12 hours after you last consumed it.

There are specialized drug panels that specifically look for psilocybin in your blood. The ability to detect psilocybin depends on several individual factors, including dosage, frequency of use, metabolism, body fat and weight, hydration and nutrition, and liver and kidney function. No two people will metabolize psilocybin in exactly the same way. In summary, shrooms do not show up on standard drug tests, and even when they do, the window for detection is quite short—typically just 1–2 days.

Hair tests

Standard drug tests, such as 5-panel or 10-panel tests, do not typically screen for psychoactive mushrooms or psilocybin. These tests usually focus on more common substances, such as amphetamines, cocaine, marijuana (THC), opioids, and phencyclidine (PCP). However, specialised tests can detect psilocybin or its metabolite, psilocin, in urine, saliva, blood, or hair follicles.

Hair sample drug tests are an effective method for detecting recent and ongoing magic mushroom use. While it may take up to 2-3 weeks for metabolites to reach the hair, once they are present, the detection window is as long as the hair sample. Each 1 cm of hair represents about one month of drug use. For example, if psilocybin is found in a 3 cm hair sample, it can be assumed that consumption occurred over a period of 3 months.

Psilocybin is rapidly metabolised into psilocin, which is then quickly cleared from the body within hours. This rapid elimination makes detection difficult unless testing occurs soon after ingestion. The half-life of psilocin is approximately 3 hours, and it is typically eliminated from the body within 15 hours.

There is a specialised hair follicle test for psilocin, the compound formed when the body breaks down psilocybin. Standard drug tests, even 12-panel ones, do not typically test for psilocybin or psilocin. However, advanced techniques like Liquid Chromatography coupled with Mass Spectrometry (LC-MS/MS) can detect psilocybin in hair samples if specifically targeted. Initial testing with authentic hair samples has shown inconsistent results, but more advanced techniques have confirmed its detectability.

Saliva tests

Psychoactive mushrooms, also known as shrooms, magic mushrooms, or hallucinogenic mushrooms, contain the psychoactive compounds psilocybin and psilocin. Psilocybin is rapidly metabolized into psilocin, which is then cleared from the body within hours. This rapid elimination makes it difficult to detect unless testing occurs soon after ingestion.

Standard drug tests primarily screen for common substances like amphetamines, cocaine, marijuana (THC), opioids, and phencyclidine (PCP). Shrooms do not typically show up on standard 5-panel or 10-panel drug tests. However, specialized tests specifically designed to detect psilocin in saliva, among other bodily fluids, can determine whether an individual has used psilocybin mushrooms. These specialized saliva tests can detect shrooms in the system for up to 24 hours, and they can detect psilocin as soon as 30 minutes after ingestion. However, saliva tests for psilocin typically only last for a few hours after ingestion, making them less common for detecting shrooms.

It is important to note that the detection window for psilocybin and psilocin can vary depending on several factors, including the type and potency of the mushroom, the dose, and the individual's body type and tolerance level. Additionally, there is a risk of mushroom contamination with other detectable drugs, which could be picked up by standard drug tests.

Overall, while it is possible for psychoactive mushrooms to be detected in saliva tests, it is not a common method of testing, and the detection window is relatively short.
