What are the three main categories of drugs?

• A. Antibiotics, Antivirals, Vaccines
• B. Depressants, Stimulants, Hallucinogens
• C. Vitamins, Minerals, Proteins
• D. Hormones, Enzymes, Carbohydrates

Answer: (B)

Drugs are commonly grouped by how they affect the nervous system. Depressants slow brain activity, which can make you feel relaxed or sleepy and can lessen coordination. Stimulants increase brain activity, boosting alertness and energy and sometimes raising heart rate. Hallucinogens alter perception, mood, and thoughts, often producing unusual sensory experiences or distortions of reality. Together, these three types cover the primary ways drugs influence the body and behavior, which is why they’re taught as the main categories in health education. Other options aren’t the standard drug categories. Antibiotics, antivirals, and vaccines are medicines used to treat or prevent infections, not a broad classification of drugs by their effects. Vitamins, minerals, and proteins are nutrients essential for health, not drugs. Hormones, enzymes, and carbohydrates are biological substances or nutrients, not the common three-way drug category used in this context.
