I think the easiest way to get around this is if you get arrested just subpoena the original doctor who signed the MMJ authorization into court. Thats what was done to Dr Orvald in Pt. Orchrad. He didn't want to show up for a court case where one of his patients was being charged so he was subpoena'd. Regular doctors here in Washington just don't seem to want to get involved in this. I know of a couple but they have been persecuted because of it.
