Which of the following is NOT one of the five families of drugs?

• A. Narcotic
• B. Antibiotic
• C. Stimulant
• D. Hallucinogen

Answer: (B)

Drugs are grouped into broad families to describe how they affect people and what law enforcement typically encounters. The five commonly taught groups are narcotics, stimulants, depressants, hallucinogens, and cannabis. Antibiotics are medicines used to treat bacterial infections; they’re not a category of abused or controlled substances and aren’t part of this five-family framework. That’s why antibiotics is the correct choice for NOT belonging to the five drug families. The other options—narcotics, stimulants, and hallucinogens—fit squarely within the established categories.
