Your mission, should you accept it, is to educate your girlfriend on the many many, benefits, in so many, many ways of mj. Get her to peruse some of the links Granny made that are in the Marijuana and Health section as a sticky. Find a copy and have her read "The Emperor Wears No Clothes" by Jack Herer (I can send you a copy to an IM or something). Be subtle but make sure she understands that "the truth is out there". Above all, keep your humor, man. Laughter is the best medicine.
