'''Deliriants''' are a | '''Deliriants''' are a subclass of [[hallucinogens]]. They display a unique property in that they easily produce solid hallucinations which integrate seamlessly into waking consciousness, similar to fully formed dreams or delusions. In contrast, classical [[psychedelics]] and [[dissociatives]] have progressive levels of multiple all-encompassing sensory effects before reaching the level of concrete hallucination. | ||
The term deliriant was introduced by David F. Duncan and Robert S. Gold to distinguish these substances from [[psychedelics]] and [[dissociatives]], due to their primary effect of causing delirium (as opposed to the more lucid states produced by other types of [[hallucinogens]]).<ref>{{cite book | vauthors=((Duncan, D.)), ((Gold, R.)) | date= 1982 | title=Drugs and the Whole Person | publisher=John Wiley and Sons | url=http://archive.org/details/drugswholeperson00dunc | isbn=9780471041207}} | |||
</ref> The term is generally used to refer to anticholinergic drugs. | |||
Despite the fully legal status of several common deliriant plants and substances, they are not popular as recreational substances due to the severe and unpleasant nature of the hallucinations they produce.<ref>{{cite book | vauthors=((Grinspoon, L.)), ((Bakalar, J. B.)) | date= 1997 | title=Psychedelic Drugs Reconsidered | publisher=Lindesmith Center | isbn=9780964156852}}</ref> | |||
In addition to their potentially dangerous mental effects (accidents during deliriant experiences are common),<ref>Datura Items | http://www.lycaeum.org/mv/mu/datura.html</ref> certain deliriants are poisonous and can cause death due to tachycardia-induced heart failure and hyperthermia even in small doses.<ref>{{cite journal | vauthors=((Beaver, K.

Use and experimentation with deliriants is generally discouraged due to their questionable safety profile. It is highly advised to use [[harm reduction practices]] if using these substances. | |||

Deliriants work via anticholinergic activity and their [[antagonist|antagonistic]] action on [[acetylcholine]] receptors. Inhibition through this mechanism leads to decreased levels of acetylcholine, causing delirium, sedation, tachycardia and intensely realistic hallucinations. However, the precise role of these interactions and how they result in the deliriant experience continues to remain elusive. | Deliriants work via anticholinergic activity and their [[antagonist|antagonistic]] action on [[acetylcholine]] receptors.

In contrast, [[cannabis]] and [[caffeine]] have a reverse effect by inhibiting acetylcholinesterase, an enzyme responsible for the breakdown of acetylcholine. This leads to increased levels of acetylcholine, and, in turn, improved cognition and stimulation; as a result, both [[cannabis]] and [[caffeine]] have an inhibitory effect on deliriants. | In contrast, [[cannabis]] and [[caffeine]] have a reverse effect by inhibiting acetylcholinesterase, an enzyme responsible for the breakdown of acetylcholine.
