People use LSD recreationally for social events, to relieve boredom, for spiritual visions, artistic inspiration, or to cope with mental health issues. Physical effects include dilated pupils, changes in body temperature, sweating, dry mouth, and visual hallucinations. Mental effects involve delusions, distorted senses, panic attacks, flashbacks, and depression. LSD goes by street names like Acid, Blotter, and Window Pane.
