Magic mushrooms are a type of fungus that contains a chemical called psilocybin. When someone eats these mushrooms, the psilocybin turns into another chemical called psilocin. Psilocin is what causes the “trippy” effects, like changes in how you see or feel things.
Some people use these mushrooms for personal exploration or research, but it’s important to know they are illegal in most places. In the United States and Canada, they are considered Schedule I drugs, which means the government says they are unsafe to use without strict medical approval.
One question that often comes up is whether these mushrooms show up on a drug test. The short answer that it doesn’t show up usually, but there are exceptions.
A lot of regular drug tests, like the ones used by jobs, schools, or hospitals, don’t check for psilocybin or psilocin. They usually look for things like marijuana (THC), cocaine, opioids, and amphetamines. These are part of what’s called a “5-panel” or “10-panel” test. Even more detailed tests, like a 12-panel, usually don’t include psilocybin.
The reason is simple: testing for psilocybin or psilocin is more expensive and not something most employers worry about. It’s also harder to detect because the chemicals leave your body quickly.
While most tests don’t look for psilocybin, there are special tests that can. These are called “specialized drug tests.” They are used in certain serious situations, like court cases, drug treatment programs, or if someone has a job that requires a high level of security.
These tests use advanced machines, like one called Liquid Chromatography-Mass Spectrometry (LC-MS), to find very small amounts of substances in the body. They’re rare and usually only done if there is a strong reason to believe someone used psilocybin.
How long psilocybin or psilocin stays in your body depends on how much was taken, your body type, and how your body processes it. But in most cases, it goes away fast. Here’s a quick breakdown:
In most cases, by the time someone takes a standard test, psilocin is already gone from the body.
A few things can make the psilocybin stay in your system longer or shorter:
A false positive is when a drug test says you used a drug, but you didn’t. With psilocybin, this is rare, but it is possible. Sometimes, certain medications or substances that are similar in structure, like LSD or some ergot-based compounds, could confuse a very basic test. However, this is extremely unlikely. If it happens, a more advanced test (like LC-MS) can be used to double-check the results and give a clear answer.
Even though magic mushrooms usually don’t show up on a drug test, it’s important to understand the risks. In many places, using psilocybin is still against the law. If someone is in a job, legal case, or program where drug testing is required, using psilocybin, even once, could create problems if a specialized test is used.
People in the military, federal jobs, or safety-sensitive roles (like pilots or certain medical workers) should be especially careful. These roles may include more advanced screening, even if most people don’t face those kinds of tests.
Even in states or cities where psilocybin has been decriminalized (like Oregon or Colorado), it is still illegal under federal law in the U.S. In Canada, it’s only legal in specific medical programs or clinical trials. Just because something is allowed in one area doesn’t mean it’s legal everywhere. In both countries, using or selling psilocybin without permission can carry serious penalties.
Knowing how psilocybin works in the body and how drug tests function helps people make safer, more informed decisions. This information is not meant to promote or encourage use. It’s important to always follow the laws in your country or state and to understand the consequences of any decisions you make.
