Does marijuana help with alzheimers?

i've read studies that show it is more effective than the leading pharma meds. interesting...no medical value?? DEA what are you smoking? i don't want whatever it is because apearantly it makes you ignore millions of testimonies and put good people where they don't belong. 2/3 of their "work" goes to erradicating a plant. basically an involuntary pest control agency. they come whether you call them or not. how is that fair?
