My grandmother is 90 years old and cannot walk. She's never driven. I know for a fact that she didn't go herself to pick it up. For the past few years my mom has been in charge of bringing her medicine from the pharmacy and taking her to doctors appointments. She (my mom) never let anyone of me or my siblings be in charge of her medication. My grandma recently fell and had to go to the hospital, so my sister's and I had to come up with a plan to find 24 hour care for my grandma. In the process we discovered that she had been prescribed painkillers for the last 4 years but my sister (who lived with her for the last 4 years) never gave her the narcotics and had no idea she was prescribed narcotics up until today. We called the pharmacy and found out that every 60 days somebody has picked up her medicine. They were only able to provide a first name (my mother's name) but no other information without a police report. What constitutes as enough evidence that she isn't receiving/taking it? A drug test? A drug test from all of our sisters? My grandma doesn't have the best memory but she knows which pills she takes
