yes, every state with legalized med use requires a dr's signature. so that means you have to have a legal need for the recommendation AND live in an enlightened state. most people licensed by whatever state jealously guard the state with this and the status of those seeking a card only to avoid conflicts with the government and the anti-med use crowd. too many times one person has ruined a good thing for the masses and we're determined to keep things running by the rules (in nevada at least) to keep this legislation on the books and show the public in general cannabis use can be handled responsibly so there's hope for future legalization regarding recreational use...and fraudulant use only hurts us all. underage use in general hurts the cause and every site allowing them to post clearly show the hazards of teenage use. i don't think anyone can argue that...a legitimate arguement anyway.
