Enforcement Reality
Psilocybin is a Schedule I controlled substance in South Dakota, and possession is a felony. While a new law will allow for FDA-approved synthetic psilocybin, this does not change the illegal status of the naturally occurring substance.
A common mistake is to believe that the new law legalizes all forms of psilocybin. The law is a 'trigger law' that only applies to synthetic psilocybin if and when it is approved by the FDA.
Local Exceptions
None identified. State law applies uniformly across South Dakota. Local ordinances may still vary — check with your city or county government for any additional rules.
