WHAT IS IT?
Hallucinogens are drugs which cause altered perception and feeling. Hallucinogens have powerful mind-altering effects and can change how the brain perceives time, everyday reality, and the surrounding environment. They affect regions of the brain that are responsible for coordination, thought processes, hearing, and sight. They can cause people to hear voices, see things, and feel sensations that do not exist.
LONG TERM EFFECTS
Most of the risks associated with hallucinogen use are associated with the risk for personal injury and life-threatening accidents. Some examples include: depression, anxiety, increased risk of developing schizophrenia or psychotic episodes, fatal liver damage (if the wrong mushroom is ingested) and flashbacks.
