Psilocybin is one of the safest substances you can find, much safer than alcohol, especially when taken in micro doses. Microdosing is proven to be safe and non-threatening. We advise that you not exceed the recommended dosage and frequency. This is because you don’t want to extend beyond your limits and potentially experience some unwanted side effects, such as temporarily losing bodily function and/or muscle weakness. Keep in mind experiences like that are not common and will go away in a few hours. Follow the dosage instructions and you’re in the clear!
If by “safe” you mean “legal,” then the answer is yes, sort of. Psilocybin mushroom dispensaries operate in a bit of a grey area, just like medical marijuana dispensaries once did. But since mushrooms are a low schedule and we’re only talking about micro doses, you needn’t worry.
