Which of the following drugs is considered a hallucinogenic?

LSD, or lysergic acid diethylamide, is classified as a hallucinogenic drug due to its profound effects on perception, mood, and cognitive processes. When ingested, LSD can cause hallucinations, altered states of consciousness, and an intensified experience of sensory stimuli. It acts primarily on serotonin receptors in the brain, which are responsible for mood and perception, leading to its characteristic effects of visual and auditory distortions.

Other drugs listed, such as cocaine, bath salts, and methamphetamines, primarily function as stimulants or have other effects but do not typically induce hallucinations at their common dosages or usage patterns. Understanding the specific pharmacological classifications of drugs is key to recognizing their effects on the human brain and behavior.
