In HSC 481.125, what term is used to describe the act of introducing a controlled substance into the body?

The correct answer encompasses all the actions listed: ingesting, injecting, and inhaling. In the context of HSC 481.125, the term used refers to any method by which a controlled substance can be introduced into the body.

Ingesting involves taking a substance orally, which allows it to enter the bloodstream through the digestive system. Injecting directly introduces the substance into the bloodstream via a syringe, leading to immediate effects. Inhaling means bringing the substance into the lungs, where it can rapidly enter the bloodstream through the alveoli.

Since all these methods effectively describe different ways a controlled substance can be introduced into the body, it is appropriate to categorize them under a single comprehensive term. Therefore, the answer encapsulates a full understanding of the various methods of administering controlled substances as defined in the health and safety context.
