I think the gp just doesn't like this liberal usage of the word "poison". Most medication is "poison" to people who are otherwise healthy. NSAIDs are bad for the stomach, pills for insomnia will make you fat, narcotics will make you fall asleep, epinephrine can stop your heart. We take them because their ill effects aren't as bad as the good they produce. Cancer chemotherapy is mostly unique because it produces a lot of suffering to someone who appears to be quite healthy. There are other medicines with horrible side effects, but you'll usually have to be obviously sick with something like malaria in order to be treated with one of those.
