Lysergic Acid Diethylamide (LSD), a powerful member of the "classical hallucinogens" family, is known for its ability to deeply alter consciousness. This psychedelic compound closely resembles serotonin, a neurotransmitter that plays a key role in mood and perception. When LSD binds to serotonin receptors in the brain, it creates a range of effects including visual hallucinations, euphoria, synesthesia (the blending of the senses), and a profound sense of connection with others or the universe itself.
