Hallucinogens/psychedelics include which of the following groups of drugs?

Hallucinogens produce altered perception, mood, and cognition. LSD and mescaline are classic psychedelics that largely modulate serotonin receptors, especially 5-HT2A, leading to vivid visual changes and altered thought. Ketamine and PCP are dissociatives that distort sensory integration and create a sense of detachment, yet they produce strong perceptual effects and are included in the broader hallucinogen category. The other groups are mainly stimulants or depressants and do not produce the characteristic psychedelic-type perceptual experiences.
