well, most of these cases of counties Instituting their OWN rules are illegal. one you are protected by FEDERAL HIPPA LAWS, which is your right as a Patient or Care Giver to be protected by Medical Information Protection via the Dr/Pt confidentiality proponants of the HIPPA laws.
So by saying you have to be on a LIST of PTs/Cg in the county your in, is a violation of the HIPPA laws, and illegal for them to do.
also, if they are going to look at your grow, then they have to have the same type of inspections on ALL grows, regardless of what veggitation is grown, including but not limited to, Annual and Perenial Flowers, Home Gardens where edible vegitation is grow like Tomoatoes, corn, squash, cucumbers ect.... anyone using any non natural form of grow equipment.
i wouldnt worry about it, but if your making money, put a lawyer on retainer. I suggest Matt Able there in the Detroit area, or Micheal Komorn out of GrandRapids. both are MMJ Specific lawyers and know the LAWs here in Mi.
