King County leaders are set to decide on whether to remove barriers to expanded research into psychedelic substances and reduce law enforcement around their personal use. The Metropolitan King County Council is set to consider a motion supporting “entheogen-related activities,” including substances such as psilocybin mushrooms, ayahuasca, and mescaline. The proposal would make investigation, arrest, and prosecution of adults using these substances among the county's lowest priorities. The resolution formalizes the council's support for entheogens as an alternative treatment option and calls on state and federal governments to allow expanded research. Supporters argue that expanding access to alternative treatments could be particularly beneficial for veterans and people struggling with addiction. Most entheogen remain classified as Schedule I controlled substances under federal law.
