The five families of drugs include narcotics, depressants, stimulants, hallucinogens, and what else?

• A. Anabolic steroids
• B. Antibiotics
• C. Vitamins
• D. Hormones

Answer: (A)

These categories describe drugs by how they affect the body. Among the commonly taught five families, narcotics, depressants, stimulants, and hallucinogens are paired with a fifth group: anabolic steroids. Anabolic steroids are synthetic variants of testosterone used to increase muscle mass and athletic performance. They’re treated as their own category because their effects, patterns of use, and legal status differ from the four other groups, which are defined by their primary effects on the central nervous system.

The other options don’t fit this framework. Antibiotics combat bacterial infections, not mind-altering or performance-enhancing effects. Vitamins are nutrients, not drugs in the abuse-category sense. Hormones regulate body processes but aren’t grouped as one of the five major drug families in this context.
