Lysergic Acid Diethylamide (LSD)

LSD is a hallucinogenic drug that is also one of the strongest mood changing drugs.  It can be found in the form of tablets, capsules, liquid, or on absorbent paper.  LSD disrupts the interaction of nerve cells and serotonin which can lead to adverse physical and biological effects.[1]

The effects of LSD are dependent in part upon the [1]:

  • Amount taken
  • User’s personality, mood, and expectations
  • Surroundings in which the drug is used

The effects of LSD are first felt 30 to 90 minutes after taking it.  The physical effects can include [1]:

  • Dilated pupils
  • Higher body temperature
  • Increased heart rate and blood pressure
  • Sweating
  • Loss of  appetite
  • Sleeplessness
  • Dry mouth
  • Tremors

LSD can also produce rapid and intense mood swings.  When taken in large doses, it can produce delusions and visual hallucinations that typically last for 12 hours.  Most LSD users decrease or stop use over time.  LSD does not produce compulsive drug seeking behavior and therefore is not considered an addictive drug.[1]

Street names for LSD include acid, Bartman, Bart Simpson, microdots, gelatin chips, blotter, and paper.
