Riedel shuttered his former location in Fallbrook because it would not have qualified for an operating permit.

The county’s year-old restrictions limit collectives to industrial areas and prohibit them from operating within 1,000 feet of places such as parks, churches, homes, schools, libraries and other medical marijuana facilities. Supervisors later approved an $11,000 annual fee for collective operators.

On Monday, more than 50 people joined the co-operative, which lists its hours of operation as 10 a.m. to 8 p.m. Monday through Saturday and closed Sunday.

About 90 percent of those who signed up were over the age of 45, Riedel said. Medical marijuana dispensaries have historically drawn the ire of neighbors who argue that many members are young and appear to be healthy.
