Final answer:
Alcohol and caffeine are indeed both considered psychoactive drugs because they alter brain function and can change mood, perception, and behavior.
Step-by-step explanation:
The question asks whether alcohol and caffeine are both considered psychoactive drugs. The answer is True. Psychoactive drugs are substances that affect brain function, leading to changes in mood, perception, cognition, or behavior.
Caffeine, commonly found in coffee, is a central nervous system stimulant and is widely recognized as a psychoactive substance. Similarly, alcohol is classified as a depressant and is also a psychoactive drug. The effects of these substances are well-documented, with caffeine typically increasing alertness and alcohol having a sedative effect.
