It’s no secret that taking magic mushrooms brings about a number of interesting effects on those who consume them.

But just how long do shrooms last? And what can you expect when the high begins to wear off?

This post will explore the various stages of a magic mushroom trip and answer some common questions about magic mushroom duration.

By the end, you’ll know exactly what to expect from your next journey into the psychedelic world of magic mushrooms!

How Long Does It Take Shrooms To Kick In?

The average onset time for shrooms is between 30 minutes to an hour after consumption. 

However, this time can vary greatly depending on a variety of factors like:

  • Potency of the dose: The potency of the dose plays a significant role in the onset time of shrooms. Higher potency doses tend to have a quicker onset time compared to lower potency doses.
  • Method of consumption: Ingesting shrooms in the form of capsules, powder, or tea can result in a faster onset time compared to eating dried shrooms.
  • Individual metabolism: The rate at which shrooms are metabolized and absorbed can vary greatly between individuals and can impact the onset time.

It’s essential to be patient and give shrooms enough time to take effect. 

Ingesting more shrooms before the effects of the first dose kick in is not recommended, as it can lead to an unpredictable and potentially dangerous experience.

If you want to speed up your shroom trip, you can soak dried mushrooms in lemon juice. This is a common technique called lemon tekking.

How Long Do Shrooms Last?

The โ€œhighโ€ from a magic mushroom trip lasts between four to eight hours. However, some people may experience a shroom high for longer or shorter periods of time.

Dosage (grams)Approximate Trip Time
1g4 hours
2g5 hours
3g6 hours
4g7 hours
5g8 hours

In some cases, the effects of shrooms can last for up to 12 hours. It’s important to be aware of the duration of shrooms, as this can help you plan for a safe and enjoyable experience.

The duration of effects caused by a psychedelic compound like psilocybin mushrooms depends on a number of factors, including dosage, setting, and individual physiology.

Some people may feel the effects for longer than 6 hours, while others may not feel them at all.

Itโ€™s also worth noting that the intensity of the effects can vary significantly from person to person during a mushroom trip.

Some users report feeling an โ€œafter glowโ€ for days following a magic mushroom trip.

How Long Do Magic Mushrooms Stay Potent?

Magic mushrooms can last for a few months to a year if stored properly in a cool and dry environment, such as in an airtight container. However, their potency can decline over time and may be affected by storage conditions, age, and method of consumption.

The potency of magic mushrooms refers to the strength of the active compounds in shrooms, such as psilocybin. It’s important to understand how shroom potency can change over time, as this can affect the quality and intensity of your experience.

Factors Affecting Shroom Potency:

  • Age: Magic mushrooms can lose potency over time, especially if they are stored in an environment that is too hot, humid, or exposed to light. The older the shrooms, the lower their potency.
  • Storage conditions: Proper storage conditions, such as a cool and dry environment, can help preserve shroom potency. Improper storage, on the other hand, can quickly degrade the potency of shrooms.
  • Method of consumption: The method of consumption can also affect shroom potency. For example, cooking or boiling shrooms can reduce their potency compared to eating them raw.

Best Practices for Preserving Shroom Potency:

To preserve shroom potency, it’s recommended to store them in an airtight container in a cool and dry environment, such as a refrigerator. 

Avoid exposing shrooms to light, as this can quickly degrade their potency. 

Additionally, it’s best to consume shrooms raw or in a dried form, as cooking or boiling can reduce their potency.

How Long Do Shrooms Stay In Your System?

Typically, psilocybin and its metabolites are detectable in the urine for 2-3 days after ingestion.

The amount of time it takes for the metabolites to leave your system varies from person to person.

It can take anywhere from a few days to a couple of weeks, so plan accordingly for any routine drug tests.

Shrooms are metabolized and eliminated from your body over time. 

Understanding the factors that affect the elimination of shrooms can give you an idea of how long they will stay in your system.

On average, shrooms can stay in your system for up to 72 hours after ingestion. 

However, this time can vary greatly depending on the dose, metabolism, and method of consumption.

Do Shrooms Show Up On A Drug Test?

It is possible that trace amounts of magic mushrooms will show up on a drug test, but it depends upon the type of drug test being used.

The most common drug tests used to detect magic mushrooms are tests that look for the presence of psilocybin and/or psilocin.

However, newer tests that can also detect metabolites such as 4-HO-DMT may be more likely to find shrooms.

There are several things that can affect how long shrooms stay in your system and how likely it is for shrooms to show up on a drug test.

These include the dose of shrooms taken, body composition, the time since ingestion, and the sensitivity of the particular drug test being used.

Additionally, certain prescription medications (such as antidepressants) can cause false positive results for mushrooms.

Types of Drug Tests For Shroom Detection:

  • Urine Tests: Urine tests are the most common type of drug test used to detect shrooms. Shrooms can be detected in urine for up to 72 hours after consumption.
  • Blood Tests: Blood tests are less commonly used to detect shrooms, as they are typically used to detect drugs with a shorter half-life. Blood tests can detect shrooms for a shorter period of time compared to urine tests.
  • Hair Tests: Hair tests can detect shrooms for a longer period of time compared to other types of drug tests, as they can detect drug use up to 90 days after consumption.

Shrooms can show up on a drug test if the test is specifically designed to detect them. 

The type of drug test and the length of time shrooms can be detected will vary depending on the type of test and the individual.

Do Magic Mushrooms Go Bad?

Just like any other perishable food item, magic mushrooms can go bad over time. The freshness of shrooms is influenced by a variety of factors, including temperature, humidity, and light exposure.

Dried mushrooms tend to last up to 10 days, but you can prolong shrooms by storing them in Tupperware or mason jars to prevent the breakdown of psilocybin.

Factors affecting shroom freshness:

  • Temperature: High temperatures can cause shrooms to dry out, reducing their potency and causing them to go bad.
  • Humidity: High humidity levels can cause shrooms to spoil, as they provide an environment for mold and bacteria to grow.
  • Light Exposure: Exposure to light can cause shrooms to lose potency over time.

To preserve shroom freshness, it is best to store them in a cool, dry place, away from light. 

Keeping shrooms in a airtight container or wrapping them in foil can also help to maintain their freshness. 

Additionally, itโ€™s recommended to consume shrooms as soon as possible after purchasing them as their potency will decline over time.

Whatโ€™s The Best Way To Store Magic Mushrooms?

Proper storage of magic mushrooms is crucial for preserving their potency and freshness. 

In order to get the most out of your shrooms, it’s important to store them in a manner that minimizes exposure to light, temperature fluctuations, and humidity.

The best practices for storing mushrooms are as follows:

  • Keep them in a paper bag: Placing mushrooms in a paper bag and leaving them in the refrigerator can help to preserve their freshness. The paper bag allows for some air circulation, which can prevent the mushrooms from becoming too moist, while the refrigerator helps to slow down the spoilage process.
  • Avoid plastic bags: Unlike paper bags, plastic bags can trap moisture and encourage the growth of bacteria and mold, which can spoil the mushrooms.
  • Store in a cool, dry place: Keeping mushrooms in a cool and dry environment can help to slow down the spoilage process and prevent them from becoming too moist.
  • Avoid exposure to light: Exposure to light can cause mushrooms to break down and become less flavorful and nutrient-dense. Store mushrooms in a dark place or wrap them in foil to minimize light exposure.
  • Use airtight containers: Using airtight containers, such as glass jars or vacuum-sealed bags, can help to preserve mushroom freshness by preventing exposure to air and humidity.

By following these best practices for storing mushrooms, you can help to ensure that your mushrooms remain fresh and flavorful for as long as possible. 

It’s important to use the mushrooms within a few days of purchasing them for best results, as their freshness and potency can decrease over time.


In conclusion, magic mushrooms can take anywhere from 20 minutes to a few hours to kick in and their effects can last anywhere from 3 to 8 hours, depending on the potency of the dose and individual factors such as body weight and tolerance. 

To preserve their potency, shrooms should be stored in a cool and dark place, away from direct light and heat. 

When it comes to elimination, shrooms can stay in the system for an average of 24 hours, but this can vary based on individual factors. 

Finally, shrooms can show up on drug tests for a limited time, depending on the type of test and individual factors such as metabolism. 

To preserve shroom freshness, it’s best to store them in a cool and dark place, in an airtight container, and to consume them within a few days of purchase. 

With this information in mind, it’s important to proceed with caution and research the effects and risks associated with consuming magic mushrooms.
