Researchers from the Department of Psychiatry, Psychotherapy and Psychosomatics at Zurich University recently discovered that LSD changes a person’s sense of meaning. Under the spell of Lysergic acid diethylamide, significance can be involuntarily added to events. This change in meaning takes place due to the stimulation of certain serotonin receptors not only during an acid trip, but after — in-other-words, with LSD, personal change may be permanent.
