The castor bean still used to make castor oil (a natural laxative) is also used to make a chemical called ricin. is castor oil (the laxative) poisonous?
The LD50 of sugar is 30g/kg of body mass whereas the LD50 of table salt is 3g/kg of body mass; clearly salt is more poisonous that sugar.
Water is safe to drink, bathe in, cook with, etc. It's LD50 is 90ml/kg of body mass in rats and probably very close in humans meaning it can kill you too. Is water poisonous?
As I mentioned, the poison is in the dose and duration not simply what the name of the drug happens to be.
From the father of the study of toxicology:
All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing poison.
