Hi all: I have a question. My new neurologist has scheduled a daTscan two weeks from now. My old neurologist prescribed medical marijuana to allow me to sleep through night-time debilitating pain (I reacted badly to all the pain meds he prescribed). The new doctor has said that he doesn't think that my two inhalations of cannabis each night before bed will mess with the results of the daTscan, but I'm a bit concerned. Does anyone have any experience with this? I would be grateful for any replies. I would rather cut out the cannabis inhalations and go without sleep for a few nights than have a skewed result ofthe test.
