I still have a bottle of a pain med that has 150 little white pills (not sure what it is but I am pretty certain that it is an opioid) that the doctor gave to me when I had back issues. I always wondered if the pharmacy or doctor had made a mistake. One hundred and fifty pills is a huge quantity.
Don't know why I never toss the old meds but I joke with my wife (sadly) that we could open up a pharmacy. We should clean out the closet.
Side question/comment: many people dump old meds into the toilet and flush them. I read that medications are not filtered at the water treatment plant so any meds end up in the city water supply.
Please, no! It pollutes the water. Take them and deliver them in person unmarked to local PD for disposal. They burn them.
I’ve always just tossed mine out in the garbage. The landfills are lined with concrete, so I don’t worry about seepage. If there is a leak, there are more problems than a couple of my old prescriptions.
Do NOT flush old meds, even in septic system. They will end up in the water coming from your tap !
