Thornton staff recommends classifying psilocybin healing centers as medical clinics; council asks for local time/place/manner options

Thornton city development staff briefed council on Colorado’s regulatory framework for “natural medicine” (psilocybin and related substances), explained staff’s recommended land‑use interpretations and requested feedback on possible local time, place and manner regulations.

Ty Robbins, city development liaison, outlined the state framework created after Proposition 122 (2022) and Senate Bill 23‑290, which decriminalized natural medicine possession and then established a licensing/operational framework. Robbins emphasized a statutory distinction: the state’s rules do not permit retail sale of natural medicine to the general public — instead, the statute regulates licensed healing centers where licensed facilitators administer medicine in supervised sessions; other regulated categories include cultivation, manufacturing and testing facilities.

Staff’s recommendation was twofold: (1) maintain staff’s interpretation that healing centers are analogous to medical clinics in the current development code and therefore can be regulated under existing clinic standards; and (2) define cultivation, manufacturing and testing as distinct uses (most analogous to the code’s “industrial inside” use) and allow them in industrial/business park and employment center districts, similar to the approach taken for marijuana testing facilities.

Robbins described how healing‑center services operate under state law: participants (age 21+) go through a preparation session (screening, medical review), an administration session (medicinal administration under facilitator supervision) and an integration session (follow‑up). State rules require at least 1,000 feet separation from licensed daycares and schools, limits on the quantity of medicine stored on site, secure storage and certain security measures, and state inspection and licensure oversight. Robbins noted nothing in state law allows home‑rule municipalities to ban these uses outright; municipalities may regulate time, place and manner.

Council members asked operational and public‑safety questions: how long administration sessions last (staff said effects generally last three to five hours and participants are not permitted to leave until effects subside), whether participants can be transported off site while still under the influence (staff said state rules require a safe transportation plan and that facilitators submit operational plans to the state as part of licensure), and how cash/security will be handled (a councilor noted concerns about cash management and robbery risk if federal banking remains unavailable). Councilors asked whether hours of operation, lighting, facade and distance restrictions could be adopted locally; staff said some municipalities are imposing operating hours, lighting/security standards, distances between facilities and prohibitions in residential zones.

Council directed staff to return with a menu of specific local time/place/manner regulations for council consideration — examples to include operating hours, exterior lighting and security requirements, façade and siting standards, prohibitions on residential locations, and distance buffers beyond the state‑required 1,000 feet from licensed daycares and schools. Staff also noted they could interpret manufacturing/cultivation/testing as industrial uses for zoning purposes and bring draft language for business licensing and zoning regulations. No formal zoning action was taken at the session; staff will return with draft regulatory language for council consideration and suggested next steps for a public‑engagement timeline.
