The target of the poison (I assume you are referring to nicotine) is nerve cells in animal -- specifically, those with "nicotinic" receptors.

As the tobacco plant does not have nerves, it is unaffected.

They are toxic to humans, not tobacco plants.

For the same reason you cannot give yourself a disease.
