Hallucinogen persisting perception disorder
What is it?
Hallucinogen persisting perception disorder (HPPD) refers to a continuation of sensations after using hallucinogenic drugs. Hallucinogenic drugs include LSD, MDMA (ecstasy) and magic mushrooms. While using them, the person’s sensory perception is altered causing what we call a trip. Some people may experience flashbacks that are the effect of the hallucinogens days, weeks, or even years after using these drugs. These flashbacks could be pleasant and enjoyable, or appear as visual effects only such as halos, distorted sizes or colors and bright lights.
