is a classical psychedelic that primarily affects serotonin receptors in the brain, particularly the 5-HT2A receptor. This interaction leads to altered sensory perception, changes in thought patterns, and heightened emotional awareness. LSD is non-addictive and is not associated with physical dependence, though its psychological effects can be intense.
Historically, LSD was studied in the 1950s and 1960s for its potential use in psychotherapy, creativity research, and consciousness studies. Today, modern research continues to explore the therapeutic potential of psychedelics, although LSD remains illegal in most countries and is classified as a Schedule I substance in the United States
