In the run-up to passage of 2020's Prop 207 legalizing adult-use recreational cannabis in Arizona, the City of Tucson began the process of reevaluating its zoning codes for what has become a billion dollar industry statewide, even before the advent of adult-use recreational sales. The process continues this month as the deadline for the Arizona Department of Health Services to finalize the rules has come and discussions continue in the chambers of Tucson city council. While the rules take shape, though, the marijuana business has quickly evolved into an economic powerhouse, creating jobs and generating revenue for the state and municipalities.
