Question: How long does it take for shrooms to kick in?
Answer: It depends on a number for factors that we will describe below.
Factors Impacting The Onset and Duration Of The Effects of Shrooms
The Type of Shroom You Ate
As we discussed in Understanding and Measuring Magic Mushroom Potency (Hint, read the article), there is a huge variability in the concentration of psychoactive substance between and within shroom genera, species and subspecies, but in general, you can assume the effects from a species like Psilocybe azurenscens will probably hit you stronger, faster and and stay with you longer than any of the Psilocybe cubensis subspecies will.
The Form of Ingestion
The form in which you consume shrooms impacts the onset of their effects. This is because after you’ve eaten the magic mushrooms, your body needs enzymatically converts the psilocybin is psilocin.
Psilocin is then absorbed from the gastro-intestinal tract, so anything that impacts this process, will alter the time of onset.
Old school dried magic mushrooms, at doses in the range of 1–5 grams hallucinogenic effects usually occur within 30 minutes of ingestion with a duration of effect of 4–6 hours.
If you are consuming fresh magic mushrooms, you need to ingest will be approximately 10 times more than you would with dried shooms in order to have a similar effect.
As we have written about previously in Magic Mushrooms: Tea vs. Eating, brewing a magic mushroom tea typically speeds up the absorption process as you do not need to digest the mushroom material to release the psychoactive ingredients.
Consuming such things as magic mushroom capsules, psilocybin gummies or psilocybin chocolate bars probably have an onset time in between that of dried mushrooms and tea as the processing of the magic mushrooms to make the product helps break down some of the mushroom material. This is balanced against a certain about of psychoactive chemical degradation that occurs when these products are produced as they typically involve some form of heat.
