Depends on the doc. Migraines are a condition that will qualify a person for medical marijuana. Try to find a doc that is known to be "medical marijuana friendly". Just tell him your situation, let him know the meds you already have work but that you don't particuarly like taking synthetic chemicals and prefer a natural remedy. I'm sure that wouldn't be a lie, would it? I don't know about Oregon but that would work down here in San Francisco.
