Which form of drug abuse involves most risk of infection with the HIV (AIDS) virus ?
- A. Cigarette smoking
- B. Using alcholo
- C. Injection of heroine

Injecting heroin carries a high HIV risk when contaminated needles or syringes are shared, because infected blood enters the bloodstream directly. Smoking, alcohol and aspirin do not normally transmit HIV in this way.
