I have constant migraines and lower back pain and i smoke marijuana that i get from a friend. but i would like to do it legally. My primary care doctor doesnt believe in medical marijuana. He told me to find another doctor who believes in the benefits of it. I cant take viks, or percs, or oxy's they dont help. my lower back pain is caused from me falling from a ladder and my lowerback hitting a rock. and i found out the alot of the doctors in rhode island wont prescribe medical marijuana. I'm trying to find a doctor that will but its hard can someone give me some advice?
