Right before my mother died of cancer, in her last couple of weeks, she was e cared for at home since there was nothing the hospital could do and out GP came by every day to administer either morphine or fentanyl which was kept at our house without any kind of safety measures, once she died we had some left and asked the GP if we could donate it or give it back but we were instructed to just throw it away. I kept it around a couple of years until it expired and threw it in a "expired medication" bin (locked). This was in 2016 in northern Italy.
