TL;DR:
Magic mushrooms typically remain detectable in the body for about 24 hours on specialized urine drug tests, though they’re rarely part of standard testing. Their psychoactive effects last about 3–6 hours, with possible mild aftereffects for up to 24 hours. Hair and fingernail tests can detect them for months, but are uncommon.
- Urine tests: detection window ~24 hours, not on standard panels
- Blood tests: detectable for ~24 hours
- Hair/fingernail tests: possible detection for months, rarely used
- Effects begin ~30 minutes after ingestion, lasting 3–6 hours
- Lingering mood or perceptual effects can last up to 24 hours
The question “How long do magic mushrooms stay in your system?” can be interpreted in two different ways:
The first is how long the metabolites your body creates after you consume them (and that can be detected on some drug tests) last. The short answer to that question for urine drug tests is about 24 hours, depending on the size of doses and frequency of use.
The second is how long the effects of magic mushrooms last. In this context, the short answer is that they last for roughly 3 to 6 hours.
Those short answers are helpful, but they only scratch the surface of each question. Let’s take a deeper dive into magic mushrooms to learn more about how long they last.
How Long Do Magic Mushrooms Usually Stay in Your System?
For Drug Tests, How Long Do Mushrooms Stay in Your System?
Mushrooms aren’t normally a result shown on standard drug tests, including urine drug tests. When urine drug tests include specialized mushroom testing, use can be detected for up to 24 hours, with about a 6-hour delay after ingestion until they can be detected, as drug testing company DNA Legal explains.
Our bodies quickly eliminate the metabolites that are formed as it processes psilocybin. Unlike cannabinoids, which can be detected for days and weeks after use with urine testing, psilocybin has a much shorter detection window.
Detection windows for other drugs include roughly 24 hours for blood tests, and several months for hair and fingernail drug tests. These tests are uncommon but are used in specific situations, such as assessing whether someone is currently under the effects of psilocybin in a medical setting or following an arrest.
For Noticeable Effects, How Long Do Psilocybin Mushrooms Stay in Your System?
Wondering how long psychedelic mushrooms stay in your system in terms of their noticeable effects or the overall length of the experience? Healthline explains that psilocybin, the active ingredient in magic mushrooms, leads to experiences that last roughly 3-6 hours.
Residual effects of the experience can last longer, up to 24 hours, for some users. The effects start about a half-hour after ingestion, less if the psilocybin is made more easily available to the body, for example, by making a mushroom tea.
The magic mushroom experience tends to gradually rise to a peak toward the middle of this 3-6 hour timeline, then gradually tapers off around the six-hour mark.
Remember that several factors can influence how intense the effects of shrooms are and how long they last, from metabolism and mental state to whether the mushrooms are taken on a full or empty stomach. Not every experience will fit neatly into the 3-6 hour window, although most do.
How Long Until Mushrooms Are Out of Your System?
Mushrooms, and more specifically psilocybin, will exit your system and become undetectable, besides the long-lasting remnants in hair and fingernail trimmings, after roughly 24 hours. The experience of using mushrooms, meanwhile, usually lasts about 3-6 hours, with some lingering effects felt up to 24 hours later.
