I am helping clear an elderly person's flat. There is a lot of unopened precription medicine. It is in date but the person has died. I offered to take it to the pharmacy to dispose of it, but my friend (who is Greek) says that in her country they send medicines to Africa and we should try to find a charity to give it to. I know it's valuable to someone, but have no idea where to start. Does anyone take medicine? There's bags full of it.
