Not long ago my mom had a miny stroke type thing, and i noticed she wasnt doin so good along with her other surgerys and she couldnt be put on any pain meds cause shes an old addict but anyway, she lcouldnt move her left arm/hand and her doctor said it would be ATLEAST A YEAR. she was really depressed, in pain and just not her self so i told her 'yo im gonna help you out' and smoked her out and got her some bud for the next month or so (she recently quit which is good) BUT! after just a over a month, she had almost full recovery in her hand and none of her recovery really showed untill she started using cannabis. its a fucking miracle worker!
