Since jerks and spasms are one of my big problems, I might be interested in marijuana, if I can't control these with magnesium, as I do now. I need at least 1000 mg of magnesium, however, nothing less will do. I do not know know if MJ would affect Porphyria, one of my other diseases, which make me react with an attack to many substances, but not all. I don't think MJ is on any safe/unsafe drug list for porphyria that I know of. I don't know if anyone on the Porph list takes it other than a dear friend in Australia, who does love the brownies, and they are one of the only things she can take, so possibly I COULD take it, if she can. I am probably not in an area where it would be as easy to find as in Phoenix (i am in Los Alamos, a scientific community in the Jemez Mountains of New Mexico). Anyway, magnesium is working for me for now.
