People, California already legalized medical MJ. You pretty much have a hangnail, you can get a card.
Of course you still have to go to California....
Interestingly, migraine headaches, which I've suffered from for about 12-14 years, were covered under the California statute last I looked. Washington State also has a medical MJ statute, but it's more restrictive, and it doesn't specifically cover migraines (doesn't necessarily rule them out, either).
Sadly, Seattle seems to be about the only place in the state that has clearly staked out a public position of being fairly understanding of people growing and using medical MJ.
But yeah...legalize it. Alcohol causes many more deaths, and it's fully legal if you're at least 21 years old. It's also more dangerous...when have you ever heard of a fight breaking out with a bunch of pot smokers? Bar fights are already a cliche'.
