Ketamine and PCP are examples of which category of drugs?

• A. General Depressants
• B. Hallucinogens
• C. Dissociative Anesthetics
• D. Analgesics

Answer: (C)

Ketamine and PCP create a distinct type of psychoactive state known as dissociation, which is why they’re best categorized as dissociative anesthetics. These drugs block NMDA receptors, reducing glutamate signaling in the brain, which leads to a separation between the mind and body—people feel detached from their surroundings and may experience dream-like or out-of-body sensations. At the same time, they produce anesthesia and analgesia, which is why they’ve been used medically for anesthesia. While they can cause perceptual distortions like classic hallucinogens, the defining feature that sets them apart is this dissociated, anesthetic state, making dissociative anesthetics the most accurate category. General depressants slow overall CNS activity, analgesics focus on pain relief, and hallucinogens is too broad a label that doesn’t capture the key dissociative/anaesthetic effects.
