How Long Do Shrooms Stay in Your System?

Magic shrooms are enjoyed all over the world for the high they produce. The active psychoactive compounds, particularly psilocybin, create an effect that is similar to LSD without the “rough edges.” Magic shroom users, also known as psychonauts, have created various ways to enjoy them. Some are eaten in salads, pizzas, and even risotto. As fun and safe as they are, people often ask, “How long do shrooms stay in your system?”

The answer isn’t as simple as you think. The length of time shrooms remain in the body depends on several factors.

The Body’s Ability to Metabolize Psilocybin

People’s bodies are different. When two people take the same amount of psilocybin, one of them is sure to metabolize the drug earlier than the other. Differences in metabolism and excretion rates are just the tip of the iceberg. They depend on other characteristics such as age, body mass, genetics, and organ health. Depending on the combination of such attributes, the body’s capability to clear itself of magic mushrooms will differ.

Age – Metabolizing magic shrooms depends on your age. Younger people tend to remove psilocybin from their systems faster than older people. Individuals past the age of 65 also have reduced blood flow to their kidneys and liver, thus delaying psilocybin’s clearance from the body.

Body Mass – Body mass refers to the combined weight and height of an individual. A person with greater body mass excretes psilocybin faster than a lightweight individual who took the same amount. Additionally, people with more body fat can excrete drugs much faster.

Liver and Kidney Function – Psilocybin is broken down by the body because of liver enzymes and certain variations in genes can facilitate the speed at which these enzymes can function. Afterwards, they are released from the body through the kidneys. People with liver and kidney disease need more time to pass psilocybin through their systems.

Food and Water Intake – Eating magic shrooms on a full stomach absorb psilocybin slower. And because psilocybin is excreted through urine, increasing water intake will decrease the time the drug stays in your system.

Metabolic Rate – Metabolic rate is influenced by genetics, age, diet, exercise, and certain drugs. A faster metabolic rate means faster psilocybin clearance from the body.

Magic Mushroom Species

The type of magic mushrooms can also affect how long psilocybin stays in the body. Greater doses will take longer for the body to excrete. Lower doses mean quicker clearance rates.

There are over 180 magic mushroom species and they all have different doses of psilocybin. Below is a list of the top 12 strongest magic mushroom species and their psilocybin content.

Psilocybe liniformans – This magic mushrooms species is found in rich pastures and grasslands across Washington, Oregon, and Michigan. Its psilocybin content is 0.16%.

Psilocybe cyanofibrillosaA native of the Northern Californian and Canadian coasts, these mushrooms make their home in soil with plenty of deciduous wood debris. It’s 0.21% psilocybin.

Psilocybe stuntziiCommonly found in well-kept lawns in the Pacific Northwest, this species has 0.36% psilocybin.

Psilocybe hoogshagenii – A more exotic variety, the P. hoogshagenii can only be seen in Mexico where it grows in small groups in humus or in muddy clay soils of coffee plantations. With 0.60% psilocybin content, no wonder it’s used in Mixtec rituals.

Psilocybe weiliiThis variety is one of the rarest magic mushrooms with the red clay soils in northern Georgia, USA as its only habitat. It has 0.61% psilocybin.

Psilocybe cubensisThe most popular magic mushroom isn’t the most potent. Aside from the USA, it’s also found in Argentina, Australia, Cambodia, Colombia, Ecuador, India, Peru, Thailand and Venezuela. Its psilocybin percentage is not too shabby at 0.63%.

Psilocybe tampanensis – Originally found in Tampa, Florida, they were never seen again until much later in Mississippi. Its body is 0.68% psilocybin.

Psilocybe cyanescensScattered across the Pacific Northwest, Western and Central Europe, parts of Australia and West Asia, the P. cyanescens is among the most common magic mushrooms with a decent amount of psilocybin clocking in at 0.85%.

Psilocybe baeocystisA solitary mushroom that grows on pastures and decaying conifer in the Pacific Northwest, this species also has an average psilocybin content of 0.85%.

Psilocybe semilanceataNative in grassland habitats and wetter areas, this magic mushroom species feeds off decaying grass roots in Canada, North America, Switzerland, Poland, Russia, and the Netherlands. It almost breaks the decimal barrier with it 0.98% psilocybin content.

Psilocybe bohemica – This species has been reported in five distinct localities in the Czech Republic. Its 1.34% psilocybin.

Psilocybe azurescensThe strongest variety of hallucinogenic mushrooms can be found in a small area of the West Coast of the United States with some feral specimens being reported in Germany. With a psilocybin content of 1.78%, this isn’t the type of magic mushrooms to be taken lightly.

Method of Taking Psilocybin

The way you take magic mushrooms can also have an impact on how long psilocybin stays in the body. Although ingestion of magic mushrooms is the most popular, psilocybin can also be extracted from magic mushrooms and injected directly into the blood stream.

Oral ingestion – Magic mushrooms which are ingested orally can be cleared from the body within 15 hours.

Intravenous injection – The drug has a more rapid metabolism when injected into the blood stream and can be cleared from the system in 6 to 7 hours.

Types of Drug Tests for Psilocybin

There are many ways to get tested for psilocybin and each method of testing has a certain window period to detect the presence of psilocybin in the body.

Urine Tests – The least invasive and the most popular testing method, urine tests involve collecting urine sample from an individual for analysis. The detection time for psilocybin in urine is 24 hours but can be as much as 48 hours in chronic magic mushroom users.

Blood Tests – Blood tests check for the presence of psilocin. They remain detectable between 3-5 hours after ingesting magic mushrooms. However, this method is usually used for scientific research.

Hair Sample Tests – A hair test for psilocybin involves collecting 20-50 hair follicles and testing the amount of psilocybin per follicle. Psilocybin can remain up to 4 weeks in a person’s hair.

Although psilocybin’s duration in the body depends on many factors, there are some “universal rules” that may apply. The hallucinogenic effect starts within an hour after ingesting magic mushrooms and you stay under their influence for 3-6 hours. It also reaches its highest peak in about 90-120 minutes.

Knowing your body and its limits is important when taking magic mushrooms. With the right research, pacing, and enlisting the help of a trip sitter, you will enjoy your psychedelic experience.
