Psilocybin is an active compound found in a majority of magic mushroom varieties. When psilocybin enters the body, it is converted into psilocin within minutes. Psilocin is responsible for the hallucinogenic effects commonly associated with shrooms.

Shrooms can be taken for recreational, spiritual, or self-improvement reasons. The effects are intense and sometimes life-altering. If you are wondering how long psilocybin stays in your system, read on to find out.


How long does it take for the effects to present?

It takes 20 to 40 minutes for the psilocybin to be converted to psilocin. At this point, the consumer starts to experience the effects since the psilocin immediately starts to act on the brain’s serotonin receptors.

The trip is characterized by introspective thoughts, spiritual awakening, and acquiring a deeper understanding of things and people. The user may also experience nausea, increased heart rate, and elevated temperature and blood pressure levels.

How long does the psychedelic high last?

It takes one and a half to two hours after ingestion for the effects to reach their peak. The consumer will feel the strength of the shrooms for the first six hours before the kidneys begin to get rid of the metabolite psilocin in the bloodstream. The whole experience may take up to 6-8 hours.

Do psilocybin and psilocin show up in a drug test?

Most drug tests are done to detect the presence of substances like opioids, marijuana, and cocaine. Some may include the screening of drugs such as benzodiazepines and barbiturates. Magic mushrooms, to be specific, psilocybin/psilocin is not included in either test.

There are specialized tests that detect the presence of psilocybin in one’s system. However, psilocybin does not stay in the body for long periods. It has been established that it takes approximately 13 hours for the compound to leave the bloodstream. This makes it near impossible for any traces of psilocybin to show up in a blood test a day or more after ingestion since the test will most certainly turn negative.  

Conducting a urine test through tandem mass spectrometry and liquid chromatography may yield better results compared to a blood test. Metabolites of psilocin can be detected via this test 24 hours after magic mushroom consumption.

Tests conducted on hair samples are more accurate and can yield a positive result up to 90 days after ingestion. However, these types of tests are rare.

If you are worried about having a positive drug test after consuming magic mushrooms, worry no more. Most standardized tests do not look for the presence of psilocybin/psilocin.  


Factors affecting how long shrooms stay in one’s system

How long psilocybin stays in your system will depend on a number of factors, the most significant being genetics, the dosage, and how frequently one consumes magic mushrooms.

Genetics: some people are genetically capable of metabolizing substances like psilocybin faster and more effectively than others. With such people, the compound will last for a few hours in the system.

Dosage: when one takes a low dosage, it is easier for the body to metabolize and eliminate it. Higher doses require more time and energy; thus, psilocybin will stay longer in the system.

Frequency: if you take shrooms frequently, it means there are always traces of psilocybin in your blood or urine. Occasional consumption gives the body time to flush out the compound.

Other factors that might influence how long psilocybin stays in your system include;

  • Liver and kidney health
  • Weight
  • Other medical conditions
  • Medications one is taking
  • Method of ingestion
  • Height
  • Age
  • Activity levels
  • Hydration
