Which illegal drug is associated with the greatest number of deaths?

• A. Heroin
• B. Cocaine
• C. Methamphetamine
• D. Marijuana

Answer: (A)

The main idea here is comparing how dangerous different illegal drugs are in terms of deaths, not just how people feel or how addictive they are. Heroin, an opioid, has a high fatal-overdose risk because even small increases in dose can severely depress breathing. In illicit markets, potency varies and contamination with potent substances like fentanyl makes overdoses much more likely, pushing the death toll higher. This combination of high per-use lethality and a large user base historically leads heroin to be associated with more deaths than other illegal drugs. Cocaine and methamphetamine can kill, mainly through heart-related problems or overheating, but their overall death counts are generally lower. Marijuana, by contrast, has a very low fatal overdose risk, so it contributes far fewer deaths.
