Drug DUIs: The effects of LSD on the DUI driver

Lysergic Acid Diethylamide (LSD) Lysergic acid diethylamide, otherwise known as LSD, LSD-25, or simply acid, is a semisynthetic psychedelic drug of the ergoline family. Its unusual psychological effects which include visuals of colored patterns behind the eyes in the mind, a sense of time distorting, and crawling geometric patterns have made it one of the most widely known psychedelic drugs. It has been used mainly as a recreational drug, and as a tool to supplement various practices for transcendence, meditation, psychonautics, art projects, and illicit (formerly legal) psychedelic therapy. The effects after consuming LSD are unpredictable and will depend on the dose ingested, the user's personality and mood, expectations and the surroundings. However, the effects typically include hallucinations, increased color perception, altered mental state, thought disorders, temporary psychosis, delusions, body image changes, and impaired depth, time and space perceptions. Users may feel several emotions at once or swing rapidly from one emotion to another. "Bad trips" may consist of severe, terrifying thoughts and feelings, fear of losing control, and despair. In the DUI context as it relates to field sobriety testing, horizontal gaze nystagmus, vertical gaze nystagmus, and lack of convergence are not present. Pupil size is dilated and the reaction to light is normal. Pulse rate, blood pressure, and body temperature are elevated.
