Patients not taking meds--
--as prescribed can = not taking their meds period. If they don't take meds they won't take the placebo with the device in it either. I suppose not getting any feedback from the device will let whomever know that they aren't taking their meds.
-- don't always have the money to take them on a regular basis so they do every other day or so. If they don't have the money to purchase their meds how can they afford $77/month for another "medication". Just a question. also if they don't have $$ for meds they may not be spending money for cell phone either.
---are sometimes those with mental problems or the homeless/wanderers who aren't always in a place (mentally or physically) to refill prescriptions or sell them or ----- these are the folks that are hard to monitor cause ya can't find them. most don't have cell phones either cause they don't have a billing address.
While I think the idea is a good one - the people who could most benefit by the proposed plan (besides the manufacturers/sellers/advertisers/insurance co...) can't or won't have access to the device.
