Answer: The answer is B: Legal issues
Legal issue is a possible consequence of abusing intravenous drugs such as heroin.

Injecting intravenous drugs into the body allows it to enter the bloodstream immediately, which increases the speed of delivery to the brain. The effect is felt immediately after injecting the drug.
