well in california, you can get a card for any condition marijuana helps with. thats whats written right into the law
any doctor that can prescribe medication can write a reccomendation, but most are afraid to, even though their rights to reccomment medical marijuana (reccomend not prescribe) is protected by the first amendment
with most doctors that do reccomendations, thats one of the few, if not the only thing they do, basically yu contact them, make an appointment, bring your relevant info (a note from your real doctor is pretty much a gurantee) pay your fee, and depending if the doctor thinks your bullshitting or if they care, youll get a note saying that you can have medical marijuana
at that point you walk into a despensary, they verify your reccomendation, and they let you in and you get to gawk at their ounces and opunces of weed on the shelves
you can also grow your own, its a good idea to have a copy of your reccommendation over your grow area, and you need to carry your reccommendation anytime youre holdingjust incase leos decide to hassle you, there is a law that limits the amount of plants to 6 mature 12 immature but depending on where you live it will be more.... i dont even plan on following those limits because they were designed for regular strains and ill be growing autoflowers which are much smaller and yeild about 1/2-1 oz each, as long as im not growing pounds and pounds and distributing it it wont be a problem
now recently there is a bill that has passed through the house and the senate here in cali that will prevent employers from discriminating against med marijuana patients because they fail the drug screening for thc, that bill is currently waiting to be signed by the governer, and hes being really lazy about it.... it would make life so much easier for those who choose natural medicine over the pharmeceuticals
