Shrooms is the street name for mushrooms containing psilocin or psilocybin. This is a psychedelic compound that induces hallucinations, where you sense things that are not present in your environment. For example, you see vivid colors, shapes, and patterns. While shrooms can lead to pleasant effects like a good trip, they can also lead to bad trips and other unwanted effects.

In this blog, we are going to explore shroom effects on your mind and body, the risks and side effects, and how long do shrooms stay in your system for drug tests.

How Long Do (Psilocybin) Mushrooms Stay in Your System?

If you are wondering how long do shrooms stay in your system, then we must really focus on how long does psilocybin stay in your system.

Psilocybin stays in your system for up to 24 hours, but depending on the drug test, it can be detected for even longer.

Factors That Affect How Long Shrooms Stay in Your Body

Shrooms typically stay in your system for 24 hours. However, everybody metabolizes shrooms at different rates, so it depends on the following factors as well:

  • Dosage and Frequency: Greater dosage and frequency of shrooms lead to longer retention times.
  • Age: As increasing age leads to slower metabolism rates, older persons can metabolize psilocybin at slower rates than younger persons. Maintaining a nutritious diet, good hydration levels, and physical activity is crucial.
  • Body Composition: Higher body weight can lead to slower metabolism rates.
  • Liver and Kidney Functioning: The liver and kidneys are the main organs responsible for metabolism and excretion. So, pre-existing liver and kidney conditions can slow down the psilocybin elimination rate.

How Are Shrooms Detected in Drug Tests?

Shrooms are detected by different drug tests, such as the following:

  • Urine Tests: Urine tests are the most commonly used drug testing methods for detecting the presence of shrooms. It can be detected in the urine for up to 24 hours.
  • Hair Tests: Hair tests have the longest detection window for shrooms. They detect the presence for up to 90 days.
  • Saliva and Blood Tests: Shrooms are metabolized very quickly to be detected either by saliva or blood tests. However, it has been estimated that shrooms can be detected by blood tests for up to 24 hours.

Effects of Shrooms and How Long They Last?

The effects of shrooms can kick in within 20 minutes after ingestion and last up to 6 hours after intake. After this, the effects begin to subside. The residual effects may linger for a day, after which your body returns to its normal condition.

A shroom trip can begin as mild, where you feel relaxed and even drowsy. At higher doses, you experience hallucinations and a distortion of time and reality. You can even experience anxiety and paranoia. In fact, shrooms can lead to the following unwanted effects:

  • Bad trips
  • Anxiety
  • Psychosis
  • Seizures
  • Coma
  • Overdose (rare).

Tips for Detoxing and Clearing Shrooms From Your System

Shrooms do not lead to physical or psychological dependence, so detoxification (detox) from shrooms involves dealing with the mental and emotional aftereffects we mentioned earlier. Typically, shrooms have a very short half-life in that they are metabolized quickly, and their unpleasant effects subside in some time.

When you are detoxing from shrooms, remove all alcohol or drugs from your vicinity. Create a relaxed environment. Drink lots of water, as water can act as your body’s natural detoxification system that flushes out toxins from the body. Call family or friends over whom you can rely if the aftereffects become overwhelming.

Risks and Precautions When Using Shrooms

We understand that staying away from shrooms completely can be challenging. So, it is your safety first. As there are risks of a bad trip and extreme feelings of paranoia, psychosis, coma, and overdose when using shrooms, here is how you can engage in harm-reduction strategies:

  • Stick to lower doses.
  • Do not mix shrooms with alcohol, prescription medication, stimulants, and other psychedelics.
  • Use shrooms only in safe and controlled settings and with trusted persons who can ensure your safety.
  • Maintain a nutritious diet.
  • Drink plenty of water.
  • Establish a consistent sleep pattern of 7-9 hours at night.
