I'm hoping that since medical marijuana is now legal in many states, my question will be considered socially acceptable. Marijuana has proven useful for other types of pain and for nausea as well, so it doesn't seem a far jump to try it for migraines.
It is legal in my state but unavailable due to some stupid glitch, and migraine is not one of the approved diagnoses.
I just keep thinking how great it would be if the only side effect of a great abortive was a bad case of the munchies.
