No city or town in Colorado is allowed to prohibit natural medicine healing centers from opening and offering supervised consumption of mushrooms and other psychedelics to adults — that much was plain in an initiative passed by the state’s voters two years ago. But local governments have enough tools in their regulatory toolbox to make the process of establishing such facilities nothing short of a bad trip, as recent rule-making in Parker, and discussions to do the same in Castle Rock, have shown. Using time, place and manner powers, municipalities can curtail hours of operation and limit the locations of healing centers to a point where players in the nascent industry may feel it’s not worth giving it a go. “It’s way too restrictive and unrealistic,” said Beth Jauquet, a psychedelic counselor and registered dietician who last week pleaded with elected leaders in Castle Rock to dial back plans to rein in an industry that voters approved in a statewide vote in 2022. Her business, Primalized Health Consultants, which offers acupuncture, nutrition counseling and massage, also provides guided psychedelic journeys that are permitted under the new state law’s provision that allows adults 21 and older to share the substances.
