Medical marijuana became legal in the city of Caro with the start of the New Year. After years of passing six-month moratoriums against developing ordinances regarding medical marijuana, the Caro city council took action in December to allow such businesses. Council passed a medical marijuana ordinance after a year of study that governs the growing, processing, sale, safety standards and secure transport within the city. The new ordinance outlines three kinds of marijuana growers: a Class A facility cannot grow more than 500 plants, a Class B facility cannot grow more than 1,000 plants, and a Class C facility cannot grow more than 1,500 plants. Marijuana facilities can be no closer than 1,000 feet from a pre-existing public or private grade K-12 school or within 500 feet of a house of worship. Fees to operate such a business within the city is $5,000 a year, to help defray administrative and enforcement costs.
