Hallucinogens are a group of drugs that alter sensory and perception processors in the brain. They have been used for centuries, most often in religious rituals. They cause the user to hallucinate and certain types can create out of control or disconnected feelings. Some common hallucinogens are LSD, peyote, DXM, ketamine, PCP, and salvia. Hallucinogens can be used in a wide variety of ways, from smoking to being brewed in tea. Short-term general effects are increased heart rate, nausea, panic, and a loss of time. Long-term effects of certain hallucinogens include speech problems, depression, anxiety, and poor memory. There is evidence to indicate that hallucinogens are addictive, but the greatest danger is that they can produce tolerance to other drugs and lead to uncontrolled drug seeking behavior¹.
