Lysergic acid diethylamide, better known as LSD, is a hallucinogenic psychedelic drug. As the Australian NGO explains Alcohol and Drug Foundation (ADF), this means that in small doses, the person who consumes it will be subject to slight changes in perception, mood or thought. Instead, “larger doses can cause visual hallucinations and distortions of space and time, ”And even provoke particularly violent behavior. In some cases (the famous bad trips), these hallucinations can lead the consumer to panic, paranoia, or provoke dangerous behaviors … even push to suicide: thinking that you can fly and jump from the top of a roof, crossing a street without seeing passing cars. If some hallucinations can be pleasant, others cause real panic, deep anguish, along with intense paranoia (for example, having the impression of being chased by a horde of vile and hungry creatures).
