How long do shrooms take to kick in?

Magic Shrooms: Onset to Aftermath

There are many ways to describe the experience of using magic mushrooms. Mind-altering. Spiritual. Psychedelic. Visual. Reality-bending. Before you reach this point of nirvana, how long do you wait for magic shrooms to kick in?

It depends on the dosage.

One dose of magic shrooms is equal to 1 gram but may be more for experienced users. When you take magic mushrooms on an empty stomach, it will take 10-60 minutes to onset. The onset is the phase where you are “coming up.” By this time, the drug’s effects are starting to grow and you’re slowly succumbing to it.

Around 60-80 minutes, you will peak. This is the highest point you’re going to get. You will remain steady at the peak for 2-6 hours before “coming down.” This is when the drug’s effects are wearing off. Sometimes, you will experience after-effects for up to eight hours.

A usual side effect after going on a trip is extreme dry mouth so remember to keep a water supply close. Some shrooms can also leave an aftertaste that can last up to 24 hours.

The desired effect of psilocybin mushrooms will depend on your dosage. Although people’s tolerance to magic mushrooms vary, this general guideline applies to most people (this guide uses dried Psilocybe cubensis as reference).


A threshold dose is equal to 0.25g. This will not create a dramatic effect. Changes in sensation include feeling cold and seeing more vivid colors.


A light dose is between 0.26-1g and it creates a noticeable effect with milder symptoms. Some of the first symptoms are the appearance of stronger colors, peripheral hallucinations, and fleeting distortions. Intense lights will start shimmering like stars. There will be slight changes when you look at walls, ceilings, or even paintings. They will appear to “breathe.” Your pupils will dilate and your hands will feel cold and clammy. Your thoughts will also exhibit some subtle changes. If this is your first time to take magic shrooms, you may experience some nausea especially if you have a delicate stomach.


A common dose would be between 1.1-2.5g. This would lead to more intense hallucinations which are harder to ignore. You’ll see patterns even when you close your eyes. There’s another effect called “crossover of sense,” where you will see music and hear colors. You can expect your moods to fluctuate. On the lighter end of the spectrum, you will feel ecstatic and enlightened. But these feelings can give way to restlessness and even depression. However, these feelings will depend on your mindset before you take the shrooms.


A strong dose starts from 2.6g upwards. A dose this high is can give you intense visual distortions and an amazing feeling but it can also send you spiraling down. Other effects include distortions of time and space, intense personal and spiritual awareness, and different perspectives of the world. Anything is possible but it may still be better to start lower if you aren’t comfortable with psychedelics yet.

If you’re taking shrooms for the first time, you may feel nauseous, paranoid and confused at the beginning of your trip. This is not a pleasant experience but these feelings will pass as you become more comfortable in the duration. If it doesn’t, just sit by yourself or with a trusted trip sitter.

      Hi Elizabeth, How unfortunate, maybe the truffles got too hot during shipping and lost their potency.

    I usually take around 4 dry grams per trip. Sometimes I have feelings of euphoria and joy, while other trips have been harder and given me panic attacks in waves. Mood, set and setting are very important. It’s best to take shrooms after fasting for 6-12hrs or the effects are diminished greatly IME. I love psilocyben cubensis mushrooms. They are the passion of my life for the past 3 and a half years now.

    A crucial thing that you touched on: YOUR MINDSET before you take shrooms is so important. I even do a little five min meditation on what my intentions for my “trip” are, including deep breaths like breathe “in with positivity” and “out wth negativity/fear”
    This has been really cool and helpful for a better experience for a lot of people. I’m no expert, just my .02 cents. Thanks for this cool site, friends!

    Nice and simple info! Thank you for this! These seem to be spot on….however, the feelings of “getting it”….like personal awareness and the connectivity of…well, the world around us…is also very strong during and also long after a dose of about 1.5-2+grams is a good thing to emphasize for some people.

    The AFTER effects (like days/weeks/even months) are documented by many scientific/academic places like John Hopkins – feelings of compassion, positivity and self-awareness are really common for 80% of study participants even 6-8 months after a SINGLE 2 gram dose!! You can check out these studies online, of course. Many participants in the clinical studies say that it was a positive life changing experience after ONE dose! I’ve had the same experience!

    Incredible these little nature made mushies! Thank you for your site!
