I asked a question earllier related to whether my idea of an inhalant was correct or not. Someone mentions something about vehicle. my question is: vehicle?

Vehicle in this context means a way of getting something from one place to another. An inhalant is a means (vehicle) for getting a substance into the human body through the nose or mouth.
