When we talk about mushrooms and drug tests, we're of course talking about the many varieties that contain the psychedelic compounds psilocybin and psilocin. These may have been used in religious and spiritual rituals for thousands of years, but they can still land you in hot water during a drug test.
Before going to a drug test, it's important to answer a few questions: When might you be tested for mushrooms? Exactly how long do mushrooms stay in urine for a drug test? What can you do to help pass a drug test?
When do mushrooms show up on a drug test?
First the good news: Mushrooms (i.e., psilocybin and psilocin) are not a targeted substance on NIDA-approved 5-panel drug tests. These tests normally look for the presence of marijuana, coke, opiates, amphetamines (including ecstasy), and PCP, although some other substances can trigger false positives. If you are absolutely sure that you only need to take one of these 5-panel tests, there is no need to worry about failing because of mushrooms.
Now for the bad news: The 5-panel drug tests are being seen as increasingly irrelevant to modern drug use. They ignore many prescription medications that can be abused, such as synthetic opioids and benzos, but they also fail to detect some other drugs like mushrooms.
This has resulted in testing labs offering extended drug tests that target a much wider range of substances. Unlike with 5-panel drug tests, there is no standard for which drugs to include, so it can vary from lab to lab. Some of these look for the presence of psilocybin and psilocin from mushrooms, while others do not. If you can get hold of the information, see if your lab is one of them.
In the absence of any solid evidence, it's best to assume you will be tested.
How long do mushrooms stay in urine for a drug test?
The metabolites from mushrooms can usually be detected in urine for 1-3 days after use, although there are suggestions it could be as many as five days for some people.
Taking a drug test after three days of abstinence should see you pass, but you may want to make this five days to be absolutely sure of passing.
How can you pass a drug test for mushrooms?
You can pass a drug test for mushrooms in much the same way as you would for other more common drugs, namely by using a detox drink or some detox pills.
When you use one of these detox drinks, it has two effects. Firstly, it gets you to pee more and flush your bladder clean, which will reduce the concentration of psilocybin and psilocin metabolites in your drug testing sample. Secondly, it contains ingredients aimed at preserving your urine's natural characteristics (e.g., color and specific gravity), so you can still pass the adulterant test.
It's important to remember that these effects are temporary, so be sure to follow your product's directions closely, especially with regards to timing and the right amount of water to drink.
