How Long Do Shrooms Last in Your System? Comprehensive Guide 2024

Psilocybin mushrooms, commonly known as “shrooms,” have been used for centuries in various cultures for their psychedelic properties. As recreational and therapeutic use of these fungi continues to gain popularity, individuals often seek information about the duration of shrooms in their system. Understanding how long shrooms last in your system is crucial for those who want to plan their experiences responsibly and navigate potential drug tests. In this comprehensive guide for 2024, we will delve into the factors influencing the duration of shrooms in your system, the effects of psilocybin, and the potential implications for drug testing.

  1. The Basics of Psilocybin Metabolism:

Psilocybin, the psychoactive compound in shrooms, is converted into psilocin in the body. Psilocin is responsible for the hallucinogenic effects experienced during a shroom trip. The metabolism of psilocybin occurs primarily in the liver, where it is broken down by enzymes. Once converted to psilocin, it interacts with serotonin receptors in the brain, leading to altered perceptions and heightened sensory experiences.

  1. Duration of Shrooms Effects:

Before delving into how long shrooms last in your system, it’s crucial to understand the duration of their psychoactive effects. A typical shroom trip can last anywhere from 4 to 6 hours, with the peak effects occurring around 2 to 3 hours after ingestion. Factors such as dosage, individual tolerance, and the setting can influence the duration and intensity of the experience.

  1. Elimination Half-Life of Psilocin:

The elimination half-life of a substance refers to the time it takes for the body to eliminate half of the ingested dose. While psilocybin itself has a short half-life, around 50 minutes, its metabolite, psilocin, has a longer half-life. On average, psilocin has an elimination half-life of 2 to 3 hours. This means that it takes the body 2 to 3 hours to eliminate half of the psilocin present in the system.

  1. Factors Affecting Duration in the System:

Several factors influence how long shrooms last in your system:

a. Metabolism: Individual differences in metabolism play a significant role. Those with faster metabolisms may eliminate psilocin more quickly than individuals with slower metabolisms.

b. Dosage: Higher doses of shrooms will result in more psilocin circulating in the system, potentially extending the duration it can be detected.

c. Frequency of Use: Regular users may build up a tolerance, affecting how quickly their bodies process psilocin.

d. Age: Metabolic rates tend to slow down with age, which may impact the duration of shrooms in the system for older individuals.

e. Health and Liver Function: Individuals with liver conditions may experience variations in the metabolism of psilocybin, potentially prolonging its presence in the system.

  1. Detection Windows in Drug Tests:

While shrooms are not commonly included in standard drug tests, some specialized tests can detect psilocin and psilocybin. These tests typically analyze urine, blood, or hair samples. The detection windows vary:

a. Urine: Psilocin can be detected in urine for up to 24 hours after ingestion, although this window may extend to 1-3 days in some cases.

b. Blood: Blood tests can detect psilocin for a shorter duration, typically up to 24 hours after ingestion.

c. Hair: Hair tests have the longest detection window, potentially revealing psilocin use for up to 90 days or more, depending on hair growth.

  1. Responsible Use and Legal Considerations:

As with any substance, responsible use of shrooms is crucial. Understanding the duration of shrooms in your system is just one aspect of harm reduction. It’s essential to be aware of the legal status of psilocybin mushrooms in your region, as regulations vary widely. Some places permit recreational or therapeutic use, while others strictly prohibit possession and use.


In 2024, as interest in psychedelics continues to grow, it’s important to stay informed about the substances one chooses to ingest. Understanding how long shrooms last in your system is crucial for planning experiences, especially in contexts where drug testing may be a concern. While psilocybin mushrooms have shown promise in therapeutic settings, responsible use and adherence to legal guidelines should always be a priority for those exploring the psychedelic realm.
