LSD is categorized as which type of drug?

• A. Stimulants
• B. Opioids
• C. Hallucinogens
• D. Depressants

Answer: (C)

LSD changes how you perceive the world, which is the defining feature of a hallucinogen. Hallucinogens cause distortions in senses—like seeing or hearing things that aren’t there, along with altered sense of time and mood. Because LSD can drastically alter perception and judgment, it seriously impairs the ability to drive safely. You may misjudge distances, react slowly, or make unpredictable choices, all of which raise the risk of a crash.

It’s not a stimulant, which would mainly increase alertness and energy; it’s not an opioid, which would produce pain relief and sedation; and it’s not a depressant, which would slow brain activity. The distinctive effect of LSD is the perceptual distortion, fitting the hallucinogen category.
