How Long Do The Effects Of Shrooms Last?

“Shrooms” or “magic mushrooms” are slang terms for psilocybin mushrooms, a type of dried mushroom that has psychedelic properties similar to lysergic acid diethylamide (LSD).

While the duration of a drug’s effects can vary based on the individual, the psychedelic effects of psilocybin mushrooms typically last up to six hours with varying levels of intensity over time. Effects typically begin after 30 minutes. Keep reading to learn more about what a trip feels like, how long the effects last, and detection windows for shrooms.

How Long Do The Effects Of Shrooms Last?

After ingestion, psilocybin is converted to psilocin, which is the psychedelic compound that causes the effects of this mushroom species. The effects of shrooms usually begin roughly 30 minutes after ingestion, and they often reach their peak effects in an hour. The psychedelic experience can then last for up to six hours.

However, like all hallucinogenic drugs, the effects of mushrooms can distort a person’s perception of time. Some people describe an “afterglow” after using shrooms, or a sense of happiness and well-being that may last for several days after ingestion.

Factors That Affect How Long Shrooms Last

The length of a mushroom trip isn’t the same for everyone. While the average trip lasts around 4 to 6 hours, some people experience effects for much longer or shorter periods. Many different factors influence how long psilocybin stays active in your system and how intense the effects feel.

Key factors that affect trip length include:

• Dosage Amount: Higher doses of psilocybin produce longer-lasting and more intense effects. A microdose might only last 2-3 hours, while a large dose can cause effects for 8 hours or more.
• Method of Consumption: Eating dried mushrooms whole takes longer to digest than drinking mushroom tea or taking them in lemon juice (lemon tek), which speeds up absorption and can shorten the overall trip length.
• Body Weight and Metabolism: People with faster metabolisms process psilocybin more quickly, leading to shorter trips. Body weight also affects how concentrated the dose is in your system.
• Stomach Contents: Taking shrooms on an empty stomach causes faster absorption and quicker onset, but the trip may also end sooner. Taking them with food slows absorption and can extend the duration.
• Mushroom Potency: Different species and growing conditions create mushrooms with varying psilocybin levels. More potent mushrooms produce longer, stronger effects even at lower doses.
• Tolerance Levels: People who use shrooms frequently build tolerance quickly. Higher tolerance means shorter, weaker effects even with the same dose.
• Individual Brain Chemistry: Each person’s brain responds differently to psilocybin based on genetics, mental health, medications, and natural neurotransmitter levels.
• Set and Setting: Your mental state and environment don’t change the chemical duration, but they affect how you perceive time, which can make a trip feel much longer or shorter than it actually is.

Because so many variables affect trip length, it’s nearly impossible to predict exactly how long the effects will last for any individual person. The best approach is to clear your schedule for at least 8-10 hours when taking shrooms, even if you expect a shorter experience. Never drive or operate machinery during this time, and make sure you’re in a safe, comfortable environment with people you trust. The unpredictability of trip duration is one more reason why having a sober trip sitter present is so important for safety.

What Does A Shroom Trip Feel Like?

The hallucinogenic experience created by consuming magic mushrooms is colloquially known as a “trip,” which may be pleasant or unpleasant depending on the individual and their environment. During a typical trip, a person may experience physical relaxation, happiness, and empathy. They may also experience sensory distortions that include intense colors, lights, and moving objects.

On the other hand, a bad trip may cause intense anxiety, reveal disturbing images, or lead to a dangerous psychosis. Both situations can cause physical side effects such as muscle weakness, nausea, and vomiting with the potential for hospitalization if larger doses are consumed.

How Long Do Shrooms Last In The Body?

Psilocin has a short half-life. Researchers studying the mental health applications of psilocybin mushrooms found that the half-life was about three hours with a standard deviation of 1.1 hours. As a result, the average person is likely to have psilocin in their system for 12 to 24 hours.

However, there are several factors that may influence how long shrooms last, including metabolism and frequency of use. Researchers did not find that weight played a significant role.

How Long Can Mushrooms Be Detected By Drug Tests?

Most types of drug tests do not look for psychedelic mushrooms. The standard five-panel drug test that many employers use is meant to detect cannabis, opioids, amphetamines, and other commonly abused substances.

However, certain specialized tests may be able to detect metabolites from shrooms, especially when they are used in higher doses over a longer period of time.

Tests that specifically detect shrooms have the following detection times:

Hallucinogen Persisting Perception Disorder

Some people develop hallucinogen persisting perception disorder (HPPD) after using shrooms or other psychedelic drugs. HPPD can cause lingering effects, often called “flashbacks” after mushroom use. HPPD episodes do not cause intense trips, but some people notice occasional visual distortions for months or even years after using psychedelics.

Much like a trip, these distortions may be pleasant or unsettling, depending on the individual.

Find Treatment For Substance Use

If you or a loved one are ready to begin recovering from drug use, contact the Substance Abuse and Mental Health Services Administration (SAMHSA) or browse our directory.

For some people, mushroom use is combined with other types of drug abuse, causing a disorder called polysubstance abuse. Whether a person is using multiple drugs or mushrooms alone, various types of addiction treatment are available.
