That's good news at least - you need to see a specialist before the online clinics will sign you forms at any rate - they need to document on the MMAR forms that a specialist has been consulted.
It's possible you'll get a specialist that's willing to sign them for you - which would be great and save you the money. However if they won't sign, your visit to them can still progress you further along your road to legality.
This is what I was told by the clinic I've been in communication with:
"You need to see a specialist. The specialist has to diagnose you. The specialist does not need to agree with the usage of medical marijuana, nor do they have to provide any special documentation in regards to it."
As I haven't yet been able to see my specialist, I don't know how the clinic will proceed with the next step. I assume the clinic will contact the specialist after my visit, to confirm the diagnosis. I'm sure there's people around here who can detail exactly how that part works

Good luck!
