Question

Quizplus · Accepted Answer

Psychoactive drugs act on brain chemistry, particularly on neurotransmitters and their receptors, altering mood, perception, and behavior. They can affect various neurological pathways and systems in the brain. A drug that affects the heart, for example, would be categorized as a cardiovascular drug, not a psychoactive drug. Likewise, a drug that targets the spinal cord would be categorized as a muscle relaxant or pain reliever, not a psychoactive drug. Liver function may be affected by drug metabolism and elimination, but it is not the primary site of drug action for psychoactive drugs.
