Magic mushrooms are famous for bending time and space, but when it comes to how long they actually last, things get surprisingly practical. Whether you’re wondering how long the effects hang around or how many doses you can get from a single batch, the answer depends on a few key factors: the strain, the dose, and how your body handles psilocybin.
The Short Answer
A single shroom trip usually lasts 4 to 6 hours, with the most intense part hitting around the 2-hour mark. The “afterglow” can stretch another few hours, leaving you thoughtful, peaceful, or just a little spaced out.
But what about how many doses are in a single batch? That’s where things get interesting, and a little mathematical.
How Many Doses in One Batch?
Most people measure shrooms by weight, not count, because each mushroom can vary wildly in size and potency. A small, skinny one might have half the psilocybin of a dense, thick stem. So when we talk about “how many doses,” we’re really asking how many grams your batch contains.
If you have, say, 10 grams of dried Psilocybe cubensis, that’s roughly 5 moderate trips (about 2 grams each) or 30–50 microdoses (0.1–0.3 grams each).
If the mushrooms are fresh, remember they contain about 90% water, so they weigh much more. Ten grams of fresh shrooms equals about 1 gram dried, a small dose.

The Timeline: From Takeoff to Landing
Here’s how a typical trip unfolds, based on findings from HealingMaps, Trap University, and Wikipedia studies on psilocybin duration.
Onset (0–60 minutes):
You start to feel something, a shift in perception, maybe a little laughter, a tingle behind the eyes. The come-up depends on whether you ate them on an empty stomach or brewed them as tea. Empty stomachs hit faster, around 20–30 minutes.
Peak (1–3 hours):
This is where visuals, emotions, and insight start to bloom. You might see colors breathe, walls shimmer, and your thoughts wander to strange but beautiful places.
Plateau (3–5 hours):
You’re coasting now, still very much in it, but more comfortable. Music sounds better, emotions are deeper, and time might feel slippery.
Come-down (5–7 hours):
Things start fading. The world slowly returns to normal, though your mind might still feel open and reflective.
Afterglow (8–12 hours):
Not tripping anymore, but still glowing a bit. You might feel unusually calm, creative, or introspective for the rest of the day, or even into the next morning.
Factors That Change How Long Shrooms Last
Even though 4 to 6 hours is the average, the trip can stretch shorter or longer depending on a few key things:
1. Dosage
The obvious one. A microdose (0.1 g) won’t make time wobble, it’ll just make you feel lightly focused or positive for a few hours. But a 3.5 g “eighth” can send you on a full odyssey. More psilocybin equals more time traveling.
2. Your Body
Your metabolism, weight, and what’s in your stomach all affect how fast psilocybin breaks down. Faster metabolisms and empty stomachs mean shorter, sharper trips. Slower digestion can stretch it out.
3. Mushroom Potency
Different species hit differently. Psilocybe cubensis is the standard reference point, but Psilocybe azurescens and P. cyanescens are much stronger. That means smaller amounts can last longer and feel more intense.
4. Tolerance
Take shrooms too often, and your brain gets less responsive to psilocybin. That means shorter trips with duller effects. Wait at least a week between doses to reset your tolerance fully.
5. How You Take Them
Eating dried shrooms hits slower but lasts longer. Tea hits faster and clears out sooner. Lemon tekking (soaking ground mushrooms in lemon juice before drinking) speeds up both onset and intensity, shorter but stronger.
How to Think About Doses and Time Together
A lot of people treat shroom trips like they have a set runtime, but it’s better to think of them as waves. Each wave lasts a little longer the more you take. Small doses lift you up gently, while big doses can feel like you’re surfing through parallel dimensions.
If you’re trying to stretch one batch across multiple sessions, start by weighing each dose precisely with a digital scale. It’s easy to underestimate potency, and you don’t want to accidentally eat three trips’ worth in one sitting.
When the Effects Fade (and When to Redose)
Once the peak passes, psilocybin breaks down fairly quickly. Most of it’s out of your system within 24 hours, though you may still feel emotionally sensitive or thoughtful.
Redosing the same day doesn’t work well because your serotonin receptors are temporarily “tired.” The second dose will feel weaker and shorter. For the full experience, wait at least a week before tripping again.
Direct Answer: How Long Do Shrooms Last?
In most cases, 4 to 6 hours from start to finish. The effects ramp up within an hour, peak for two, and fade over the next few. One gram of dried shrooms is roughly one light trip. One ounce (28 grams) can hold anywhere from 10 to 20 solid doses, depending on how strong they are and what you call “a trip.”
So one batch of shrooms can take you on many journeys, it just depends how far you plan to go each time.
Final Thoughts
Time moves weird on shrooms. What feels like hours might be minutes, and what feels like a lifetime might be the length of a song. But outside of the experience, most trips land squarely in that 4–6 hour window.
As for how many doses one batch holds, it’s less about numbers and more about intention. Each trip is its own adventure, and every gram is just a ticket. The real journey happens in your mind, not your scale.
