I live in CA, and I'm renewing my card later this week. The doctor that I went to last year closed, and the one that I'm planning on going to says that they need the name, address, phone and fax number of my primary healthcare provider. They also said that if your bringing any prescription bottles (which I am) that they need to have the contact info of the prescribing physican on them. I don't want them to contact my primary physican just in case they have opposing views of using medicinal marijuana. Are they just keeping the contact info for their records or do medical marijuana doctors usually call your physican?
