I read the article and while the potential applications for such a device are far-reaching, I also would be concerned about malfunctions. Under-dosing can be as bad as over-dosing and what happens if the containment pouch (whatever) for the medication leaked somehow? Breast implants leak all the time and granted, I don’t expect them to be made out of silicone, it’s an example.
I wonder how much something like this would cost?
For those with dementia, bipolar, epilepsy, those wanting contraception but with the ability for it to stop, it would be a brilliant idea. Chemical castration, as I believe was alluded to. Very good.
