Hallucinogens
Hallucinogens are substances that alter our perception of reality. These drugs give us an imagined and unreal experience endangering us by creating fear, panic attacks, mood swings and paranoia.
Four common hallucinogens are LSD (D-lysergic acid diethylamide), PCP (Phencyclidine), Psilocybin (derived from some varieties of mushrooms), and Peyote (from which Mescaline is found).
