Introduction: Why More Americans Are Asking “How Long Do Shrooms Last?”
With renewed interest in psychedelics sweeping across the U.S., more people than ever are exploring the effects of psilocybin mushrooms—commonly referred to as “shrooms.” Whether for therapeutic potential, microdosing, or recreational use, one of the most commonly asked questions is: how long do shrooms last?
In this guide, we’ll break down the typical duration of a shroom trip, what factors influence how long it lasts, and what to expect during the experience. We’ll also look at current trends, scientific research, and legal changes surrounding psilocybin in 2024–2025.
What Are Shrooms?
“Shrooms” typically refer to psilocybin mushrooms, a group of fungi that contain the hallucinogenic compounds psilocybin and psilocin. When ingested, these compounds affect serotonin receptors in the brain, altering mood, perception, and cognition.
There are over 180 known species of psilocybin-containing mushrooms. The most common include:
- Psilocybe cubensis
- Psilocybe semilanceata (Liberty Caps)
- Psilocybe azurescens
While historically used in spiritual and religious ceremonies, psilocybin has gained scientific interest for its potential in mental health therapy, including treatment-resistant depression and PTSD.

How Long Do Shrooms Last?
Average Duration of Effects
The effects of shrooms typically last 4 to 6 hours, though this can vary widely depending on several factors.
Here’s a breakdown of the general timeline:
| Phase | Duration | What to Expect |
| Onset | 20–60 minutes | Light visuals, body sensations |
| Peak | 2–3 hours | Strong visuals, altered thinking, euphoria |
| Come-down | 1–2 hours | Effects taper off, fatigue may follow |
| Afterglow | 6–24 hours | Mild clarity or introspection, sleepiness |
While the acute psychedelic effects usually fade within 6 hours, the aftereffects—including emotional shifts or fatigue—can linger for another day or so.
How Long Do Shrooms Stay in Your System?
Even after the visible effects subside, psilocybin and its metabolite psilocin can remain detectable in your system for varying amounts of time:
- Urine: Up to 24 hours (occasionally 1–3 days in heavy use)
- Blood: 6–12 hours
- Hair: Up to 90 days (though rare in drug testing)
That said, standard drug tests in the U.S. do not typically screen for psilocybin unless specifically requested.
For more detailed testing data, see the Substance Abuse and Mental Health Services Administration (SAMHSA).
Factors That Influence How Long Shrooms Last
Everyone’s experience with shrooms is different. Several variables influence the intensity and duration of a trip:
1. Dosage
- Microdose (0.1–0.3g): Subtle effects, little to no visuals
- Low dose (0.5–1.5g): Mild to moderate experience
- Moderate dose (2–3.5g): Strong visuals and deep introspection
- High dose (4g+): Intense trip, possible ego dissolution
Higher doses last longer and peak more intensely.
2. Mushroom Species and Potency
Psilocybe azurescens, for example, is significantly more potent than Psilocybe cubensis, meaning effects could be longer and stronger.
3. Your Body and Metabolism
Factors like body weight, gut health, liver function, and previous psychedelic experience can all affect absorption and processing speed.
4. Consumption Method
- Raw or dried mushrooms: Slower onset
- Shroom tea or lemon tek: Faster and more intense onset, possibly shorter duration
- Capsules or edibles: Variable absorption depending on contents and stomach contents
5. Food Intake
Taking shrooms on a full stomach can delay onset and reduce peak intensity. On an empty stomach, effects hit faster and harder.
What Does a Shroom Trip Feel Like?
Here’s what many users report during a typical psilocybin experience:
- Visual distortions (patterns, colors, movement)
- Heightened emotions
- Time distortion (minutes may feel like hours)
- Deep thoughts or insights
- Enhanced connection to nature or others
- Occasional anxiety or confusion, especially at higher doses
The Come-Down and Aftereffects
After the peak, many users feel:
- Fatigue or sleepiness
- Slight disorientation
- Emotional openness or introspection
- Decreased appetite
Legal Status of Shrooms in the U.S. (2024–2025)
As of 2025, psilocybin remains federally illegal and classified as a Schedule I substance under the Controlled Substances Act.
However, several U.S. jurisdictions have decriminalized or legalized psilocybin for medical or personal use:
Legal or Decriminalized States/Cities (as of 2025):
- Oregon: Legalized psilocybin therapy (via licensed facilitators)
- Colorado: Legal for personal use and therapeutic settings (under Proposition 122)
- Oakland, CA; Seattle, WA; and others: Decriminalized personal possession
Track evolving laws through the Drug Policy Alliance or your state’s department of health website.
Can You Shorten or Extend a Shroom Trip?
While you can’t fully control the duration, some practices may moderate the intensity:
To Soften or Shorten a Trip:
- Eat before or during the experience
- Stay in a calm, familiar environment
- Take a lower dose
- Use lemon balm tea or CBD to relax the body
To Maximize the Experience:
- Fast beforehand
- Try “lemon tekking” (soaking shrooms in lemon juice to convert psilocybin into psilocin faster)
- Practice breathwork or meditation to deepen the experience
Important: Combining shrooms with other substances (including alcohol or cannabis) is not recommended, as it can increase risks of adverse effects or anxiety.
Microdosing and Duration
Microdosing psilocybin involves taking very small doses (usually 1/10th of a full dose) on a set schedule, often every three days.
- Effects last 2–6 hours but are subtle—boosting mood, focus, or creativity without hallucinations.
- Microdosing remains legally restricted in most U.S. states.
Recent studies, like those published by Johns Hopkins University, suggest potential mental health benefits, though more research is needed. View their research center on psychedelics.
Safety Tips for First-Time Users
If you’re considering trying shrooms, take the following precautions:
- Start low and go slow
- Have a trusted trip-sitter (especially for higher doses)
- Choose a safe, familiar setting
- Avoid if you have a history of psychosis, schizophrenia, or bipolar disorder
- Stay hydrated and rest afterward
Conclusion: Respect the Journey
So, how long do shrooms last? While the peak effects may wear off after 6 hours, the mental and emotional impact can linger much longer. Whether you’re exploring psilocybin for curiosity or therapeutic potential, it’s crucial to understand the duration, context, and legality of your journey.
Thinking about trying psilocybin mushrooms? Make sure you understand how long shrooms last, how they affect your mind and body, and what laws apply in your state. For those curious about microdosing or psychedelic therapy, consult with a medical professional or therapist trained in psychedelic integration.
