Lysergic acid diethylamide, known as LSD, is one of the most powerful hallucinogens out there. It is a drug of extreme unpredictability, and is banned for use in the United States, even though it was once used as a psychiatric drug, and has been used in secret government tests.
LSD is lysergic acid diethylamide. LSD was discovered in 1938. It is manufactured from ergot, a fungus that grows on rye. LSD dissolves in water and is odorless, colorless, and tasteless. A dose the size of a grain of salt can cause effects. LSD inhibits the movement of serotonin in the brain, which influences mood. LSD seems to work in the cerebral cortexof the brain, which is involved in mood, thought, and perception, and in the locus ceruleus of the brain, which coordinates sensory perceptions.
