FRESNO, Calif. (KFSN) -- Medical marijuana dispensaries in Fresno County could be a thing of the past if Sheriff Margaret Mims gets her way. The county supervisors will discuss a proposal Tuesday aimed at eliminating most of these collectives.

Sheriff Mims put a 20 page report on the agenda for the Board of Sups meeting. Supporters say it will help the Sheriffs Office control the cultivation of medical marijuana in Fresno County while critics say the ordinance makes it nearly impossible for anyone qualify and grow the plant.

Under the new ordinance proposal -- medical marijuana collectives like the one at Tarpey Village will cease to exist. And anyone who wants to grow pot legally will have six months to do so in the industrial area of Fresno County, where they'll be at least a thousand feet away from schools, parks, and churches.

Supervisor Henry Perea says the ordinance will help stop illegitimate grows taking place all over the county. "Really what I think it's turned into is a lot of criminal activity that has taken advantage of a law that was intended to help people. And we're going to put a stop to that in Fresno County." said Perea.
