A hallucinogen is a psychoactive agent which can cause hallucinations, perception anomalies, and other substantial subjective changes in thoughts, emotion, and consciousness .The common types of hallucinogens are psychedelics, dissociatives, or deliriants.y contrast, Stimulants, Opioids, and other psychoactive drugs are not explicitly hallucinogens because a 'hallucination' is visual terminology. The psychoactivity of opioids is devoid of visual anomalies, though the 'numbing' can be considered dissociation from pain.
Use of hallucinogenic drugs also produces tolerance to other drugs in this class, including psilocybin and peyote. Use of classic hallucinogens does not, however, produce tolerance to drugs that do not act directly on the same brain cell receptors.In other words, there is no cross-tolerance to drugs that act on other neurotransmitter systems, such as marijuana, amphetamines, or PCP, among others.ike LSD and psilocybin, DMT produces its effects through action at serotonin (5-HT) receptors in the brain (Strassman, 1996).
