Santa cruz County Supervisors are set to consider an ordinance this week, which would extend a moratorium, and establish new restrictions on medical marijuana dispensaries in the county. The ordinance would force dispensaries to comply with a series of rules, designed to ensure safety and establish more regulation. They include making sure the dispensaries operate as non-profit Co-operatives, meaning those that operate them are supposed to grow and share the marijuana themselves. Advertising medical marijuana would be prohibited, and zoning laws would prevent collectives from opening within 6-hundred feet of a school. The Board of Supervisors is set to debate those, and several other provisions in the ordinance, at their meeting scheduled for Tuesday.
