Mushrooms In Drug Tests: What You Need To Know

Magic mushrooms, commonly known as shrooms, are classified as a controlled substance in many regions. While they are unlikely to show up on standard drug tests, specialized tests can identify their use in certain circumstances. The detection window for magic mushrooms depends on the type of test and varies from up to 24 hours for urine and saliva tests to 3-6 months for fingernail tests. Hair tests can detect magic mushroom use for up to 90 days, but they are rarely administered due to their cost.

Standard drug tests

The 5-panel test typically detects substances like THC, opioids, and amphetamines. The 10-panel test, though less common, is also used by many employers. Other standard panel tests, such as 8- and 12-panel tests, are also unlikely to detect mushrooms.

While standard urine tests do not screen for psilocybin or psilocin, specialized urine tests can detect these compounds. The detection window for psilocin in urine is generally up to 24 hours after ingestion, though it can extend to 48 or even 72 hours depending on factors such as the dose taken and the individual's metabolism.

Blood tests are less common for detecting mushroom use due to their invasive nature and the short detection window, typically no more than 24 hours after consumption.

Standard hair tests rarely screen for psilocybin, but specialized methods like Liquid chromatography coupled with mass spectrometry (LC-MS/MS) can detect it if specifically targeted. Hair tests can reveal past mushroom use, with a detection window of up to 90 days. However, these tests are not very common due to the cost involved.

Fingernail tests also have a long detection window of 3 to 6 months, but they can take longer to show results and are rarely administered due to their specialized nature.

Specialized tests

Standard drug tests, such as the commonly used 5-panel urine test, typically screen for substances like THC, opioids, and amphetamines. Psilocybin and psilocin, the active compounds in magic mushrooms, are not usually included in these routine tests. Therefore, shrooms are unlikely to be detected unless a specific test for these substances is requested.

Hair tests can detect psilocybin for up to 90 days after use, but standard hair tests rarely screen for this substance. Fingernail tests can also detect psilocybin for up to six months, but they are rarely administered due to their specialized nature. These tests are more expensive and less common than urine tests.

Detection times

The detection times for magic mushrooms depend on the type of test used and individual factors. Here are the typical detection times for various testing methods:

Urine Tests

Urine tests are the most common type of drug test. Standard urine tests typically do not include psilocybin or psilocin in their panels, so they will not detect magic mushroom use. However, specialised urine tests can detect these substances. The detection window for psilocybin in urine is usually within 1 to 3 days after use, although it can vary from 24 hours to 72 hours, depending on factors such as the dose, individual metabolism, and kidney function.

Blood Tests

Blood tests are less common due to their invasive nature and shorter detection window. Psilocybin or psilocin are detectable in blood for a short period, typically up to 15 hours, but it can be as short as a few hours. Blood tests are most useful when recent use is suspected.

Hair Tests

Hair follicle tests are less common but can provide a long-term perspective, detecting drug use for up to three months. They are often used by legal authorities and healthcare providers due to their comprehensiveness. Hair tests can indicate a history of usage and provide a snapshot of drug use over time.

Saliva Tests

Saliva tests have a short detection window, typically lasting only a few hours after ingestion. They are not commonly used to detect magic mushrooms and are generally employed in specific circumstances.

Fingernail Tests

Fingernail tests have a long detection window of 3 to 6 months, but they can take longer to show positive results (up to 2 weeks). Drugs like psilocybin become incorporated into the keratin fibres as the nail grows.

It is important to note that the detection times can vary depending on individual factors such as dosage, potency of the mushrooms, type of mushroom, personal tolerance level, and metabolism. Additionally, magic mushrooms may not be included in standard drug test panels, so they may require specialised tests for detection.

False positives

Standard drug tests, such as the commonly used 5-panel urine test, typically screen for common substances like THC, opioids, cocaine, amphetamines, and PCP. Psilocybin and psilocin, the active compounds in magic mushrooms, are not usually included in these routine tests, meaning that shrooms are unlikely to be detected unless a specific test for these substances is requested. False positives for psilocybin are rare but can occur, especially with less specific tests, due to the potential cross-reactivity with other substances.

Standard 5, 8, 10, or 12-panel urine tests do not include psilocybin or its metabolite psilocin. However, specialized tests can be requested in legal scenarios like child custody disputes. These tests specifically look for psilocybin in urine, saliva, blood, or hair follicles to detect if someone has used psilocybin mushrooms.

Hair sample drug tests are the most effective method of detecting recent and ongoing magic mushroom misuse. Although it might take up to 2/3 weeks for the metabolites to reach the keratin fibres of the hair, once they do, each 1 cm of hair represents one month of drug misuse. If psilocybin is detectable in 3 cm of hair, legal professionals can assume consumption was ongoing for 3 months.

Fingernail tests are another way to detect psilocybin use. The metabolite psilocin travels out of the capillaries in the fingernails, becoming trapped in the keratin fibres, giving a detection window of roughly 3-6 months. This method takes longer to show results and is rarely administered due to its specialized nature.

Legal consequences

The legal consequences of possessing, consuming, cultivating, or distributing psilocybin mushrooms vary by region. In most places, including the United States, psilocybin is considered a Schedule I controlled substance, indicating a high potential for abuse and no accepted medical use.

In the United States, the Misuse of Drugs Act 1971 classifies magic mushrooms as a Class A drug, carrying the most severe penalties. Possession of magic mushrooms can result in up to seven years of imprisonment, an unlimited fine, or both. Producing and supplying them can lead to life imprisonment, an unlimited fine, or both.

While some regions have decriminalized or deprioritized enforcement, legal consequences can still apply. For example, in certain states, possession of psilocybin mushrooms can result in substantial fines or even jail time.

Legal professionals may request a court-ordered psilocybin test in various legal scenarios, including public intoxication, assault, road traffic accidents, and child custody disputes. A positive test result can have significant legal ramifications, impacting child custody arrangements and leading to criminal charges or civil penalties.
