Can Cannabis Help Migraines?

I have been plagued with migraines for the last 20 years. I have tried everything and sometimes it helps, but most of the time it doesn’t. I’ve never tried cannabis and I’m a little bit afraid, but willing to put up with the high if it will ease my pain. I figure I can ’t function with the pain, so what does it matter if I get high? Thanks for your help.
