Hallucinogens can be broadly categorized into two main types: classic hallucinogens and dissociative hallucinogens. Classic hallucinogens, such as LSD, psilocybin (magic mushrooms), and mescaline, primarily affect serotonin receptors, leading to altered perceptions and sensory experiences. Dissociative hallucinogens, like PCP and ketamine, produce feelings of detachment from reality and can affect glutamate receptors. Both types can lead to profound changes in thought, emotion, and perception.
