Current psilocybin laws and regulations in Arizona
Psilocybin is illegal under Arizona state law and federal law — possession, sale, and cultivation can carry criminal penalties, and no Arizona city has decriminalized entheogenic plants or fungi. Arizona has, however, become notable for funding psilocybin science: state lawmakers approved millions of dollars for clinical research into psilocybin-assisted therapy, signaling growing institutional interest even as personal use remains prohibited. There is no licensed or retail access pathway in the state as of 2026.
Arizona's budget allocated multimillion-dollar funding for clinical research into psilocybin-assisted therapy through state universities and research institutions.
State-funded psilocybin research efforts move forward while possession and sale remain illegal under Arizona law.
Psilocybin remains a controlled substance statewide; no Arizona city has decriminalized it and there is no licensed therapeutic or retail program.
