Which type of drug is known to have both analgesic and hallucinogenic effects?

The correct answer is PCP. This drug is classified as a dissociative anesthetic, which means it can produce both analgesic (pain-relieving) and hallucinogenic effects. PCP interacts with the NMDA receptor in the brain, which contributes to its unique properties, including feelings of detachment from the body and the environment, as well as experiences of hallucinations.

Marijuana primarily acts as a psychoactive substance with effects that are more aligned with relaxation and altered perception rather than strong analgesic or hallucinogenic effects. LSD is well-known for its intense hallucinogenic effects but is not recognized for analgesic properties. Alcohol can cause sedation and mild pain relief but does not typically produce true hallucinogenic effects like PCP does.
