Inversely, PCP can have more unpredictable effects and has often been classified as a stimulant and a depressant in some texts along with being as a dissociative.

While many have reported that they "feel no pain" while under the effects of PCP, DXM and Ketamine, this does not fall under the usual classification of anesthetics in recreational doses anesthetic doses of DXM may be dangerous.

Rather, true to their name, they process pain as a kind of "far away" sensation; pain, although present, becomes a disembodied experience and there is much less emotion associated with it. As for probably the most common dissociative, nitrous oxidethe principal risk seems to be due to oxygen deprivation.

Injury from falling is also a danger, as nitrous oxide may cause sudden loss of consciousness, an effect of oxygen deprivation. Because of the high level of physical activity and relative imperviousness to pain induced by PCP, some deaths have been reported due to the release of myoglobin from ruptured muscle cells.

High amounts of myoglobin can induce renal shutdown. This concern is partly due to William E.

The term was introduced by David F. Duncan and Robert S. Gold to distinguish these drugs from psychedelics and dissociativessuch as LSD and ketamine respectively, due to their primary effect of causing deliriumas opposed to the more lucid states produced by the other hallucinogens.

These are said to be anticholinergic. Many of these compounds are produced naturally in the nightshade plants, family Solanaceae. These tropane alkaloids are poisonous and can cause death due to tachycardia -induced heart failure and hyperthermia even in small doses.

Additionally, over-the-counter antihistamines such as diphenhydramine brand name Benadryl and dimenhydrinate brand name Dramamine also have an anticholinergic effect.

This may be explained by the familiarity of both A. Nutmeg has deliriant and hallucinogenic effects as well due to some of its psychoactive chemicals, such as myristicinwhich may be anticholinergic like the tropane alkaloids of the nightshade plants, or as suggested by Alexander Shulginpartially metabolized into the empathogen-entactogen MMDA.

In the context of religious practice, psychedelic drug use, as well as other substances such as tobacco hypnoticare referred to as entheogens.
