Transferring Medical Marijuana card from Oregon

Has anyone with their Washington State medical marijuana cards been able to transfer from Oregon? Im thinking of moving to Washington, and was wondering, would I be able to transfer my medical recommendation from Oregon or do I have to go and visit a new doctor in the state of Washington and repeat the process?

Also, how many patients can one grower actually grow for?
Feel free to also leave doctor recommendations.

You go and visit a doctor....the state of WA doesn't have anything to do with MMJ you just need a doctors recomendation but have to be a WA resident

Much easier to obtain a reccomendation (card) in wa than in oregon
