Avery Albino Magic Mushrooms

What effects will different doses of psilocybin have?

For each level of effects, we’ll estimate the psilocybin content and describe potential effects, from what experienced psychedelic consumers report and also results published in human clinical trials.

Low dose

Amount: 1 gram

One gram of magic mushrooms is commonly considered a low dose that still produces noticeable effects. These usually aren’t full-blown psychedelic effects with overt visuals or a break from consensus reality; you’re more likely to report euphoria and an enhancement of the senses, such as seeing more vibrant colors.

At 1% psilocybin content, this would be 10 milligrams (mg) psilocybin. Note: This should not be considered a microdose; it is a low, noticeable dose.

Medium dose

Amount: 1.75 grams

If you have an eighth-ounce of magic mushrooms—a common quantity—and consume half of it, that would be 1.75 grams, or about 17.5 mg total psilocybin.

You will likely experience some psychedelic effects, including open- and closed-eye visuals, synesthesia (blending of the senses), and a heavier euphoria. However, you may not experience a complete dissolution of your normal sense of self, or the truly mind-blowing effects people report from higher doses.

High dose

Amount: 3.5 grams (an eighth-ounce)

An eighth-ounce, or 3.5 grams of dried mushrooms, will have around 35 mg psilocybin content.

Ready or not, you’re going to have a full-blown psychedelic experience that will include heavy perceptual and cognitive distortions. You may or may not be able to hold a conversation or accurately perceive your surroundings, especially at the peaks, which often come in waves.

No two trips are exactly alike, but you’re pretty much guaranteed to look back on this as a stand-out experience of your life. It is not advisable to take a high dose unless you have a safe, supervised setting to take them in.

Ultra-high dose

Amount: 5 grams

The late Terrence McKenna famously described the “heroic dose,” his preferred way of diving into the full depth of the mushroom experience: Five dried grams of mushrooms in silent darkness. At 1% psilocybin content, five grams will contain about 50 mg of psilocybin.

At this dose, there’s not much you can do but lay down somewhere comfortable and let the experience wash over you. “You” won’t really be there once it hits. It will most likely be overwhelming, perhaps bizarre, and indescribable.

Taking a dose this large is rare. Few people, even experienced psychonauts, ever take this much. It is not advisable to take even close to this dose without significant experience and an ultra-safe, comfortable setting.
