• B. Antibiotics, Antivirals, Antifungals, Vaccines
• C. Vitamins, Minerals, Enzymes, Hormones
• D. Analgesics, Antidepressants, Sedatives, Hormones

Answer: (A)

Psychoactive drugs are substances that change brain function to affect mood, perception, or behavior. The four major categories commonly taught are stimulants, depressants, opiates, and hallucinogens. Stimulants increase alertness and energy; examples include caffeine, nicotine, cocaine, and amphetamines. Depressants slow brain activity and can impair coordination and judgment; examples include alcohol and sedatives like benzodiazepines or barbiturates. Opiates relieve pain and often produce drowsiness; examples include morphine, heroin, codeine, and oxycodone. Hallucinogens distort perception and thought, leading to altered sensory experiences; examples include LSD, psilocybin mushrooms, and mescaline. The other options mix in substances that aren’t typically grouped as the four psychoactive categories, such as antibiotics, antivirals, and vaccines, or treat conditions with drugs that aren’t part of this standard framework, or list nutrients or non-psychoactive substances.
