You can also check the ASA website - ASA.:.Advancing Legal Medical Marijuana Therapeutics and Research - for more info. They have a great Legal section and all sorts of info on MMJ.

If you can afford to join (I think $35 annually) it is a great cause since they organize legal response and other important MMJ initiatives. I am a member and receive their weekly newsletters to keep informed on my rights and what is happening at a state and federal level.
