Deliriant

The toxic berry of Atropa belladonna which contains the tropane deliriants scopolamine, atropine, and hyoscyamine.

Deliriants are a subclass of hallucinogen. The term was coined in the early 1980s to distinguish these drugs from psychedelics such as LSD and dissociatives such as ketamine, due to their primary effect of causing delirium, as opposed to the more lucid (i.e. rational thought is preserved better, including the skepticism about the hallucinations) and less disturbed states produced by other types of hallucinogens.[1] The term generally refers to anticholinergic drugs, which are substances that inhibit the function of the neurotransmitter acetylcholine.[1]

Common examples of deliriants include plants of the genera Datura and Brugmansia, both containing scopolamine, as well as higher than recommended dosages of diphenhydramine (Benadryl).[2][3] A number of plant deliriants such as that of the Solanaceae family, particularly in the Americas, have been used by some indigenous cultures to reach delirious and altered states of consciousness for traditions or rituals, such as rites of passage, divination or communicating with the ancestors.[4] Despite their long history of use, deliriants are the least-studied class of hallucinogens in terms of their behavioral and neurological effects.[5]
