A usual effect range is not a guarantee
Poison-control guidance describes psilocybin effects lasting roughly four to six hours, with individual variation. Processed products can add uncertainty about ingredients and timing. Do not assume the contents or remaining effects from the package name alone. [1][2]
Food spoilage and chemical potency are different
A product can be unsafe because of storage or contamination regardless of whether a psychoactive compound remains active. Conversely, a normal appearance does not verify ingredient identity or strength. There is no universal expiry period for all mushroom chocolates, drinks and gummies. [3][2]
Use credible storage instructions and protect children
Keep products in their original labeled packaging and away from children and pets. Do not taste an uncertain product to test it. If the storage history or ingredients are unknown, a best-before guess is not a safety assessment. [1][4]
Do not redose according to an assumed clock
Imagine an edible seems slow to act and the person considers another piece. Unknown ingredients and variable effects make that an unsafe prediction. Seek advice for troubling symptoms rather than using a general duration range to manage additional exposure. [5][1]
| Question | Depends on |
|---|---|
| How long effects last | Compound, exposure and person |
| How long food keeps | Recipe, packaging and storage |
| Whether it is still potent | Not established by appearance |
| When driving is safe | Recovery, not a package estimate |
