Encyclopedia > Dissociative drug

A dissociative is a drug which reduces (or blocks) signals to the conscious mind from other parts of the brain, typically, but not necessarily, or limited to the physical senses. Such a state of sensory deprivation and dissociation can facilitate self exploration, hallucinations, and dreamlike states of mind which may resemble some psychedelic mindstates. Essentially similar states of mind can be reached via contrasting paths—psychedelic or dissociative. That said, the entire experience, risks and benefits are markedly different. Senses are the physiological methods of perception. ...

The primary dissociatives are similar in action to phencyclidine (PCP), and include ketamine and dextromethorphan. Also included are nitrous oxide (laughing gas), salvia divinorum, and muscimol from the amanita muscaria (fly agaric) mushroom.

Amanita muscaria constituents

These four groups of dissociatives have slightly different effects but also share similarities separating them from other classes of hallucinogens. They are markedly different from psychedelics such as LSD, where alert and fully conscious users experience cognitive distortion while simultaneously interacting with the "real world". Hallucinations from these dissociatives are generally only experienced in dark rooms or with eyes closed, unless at very high doses above what is normally consumed recreationally. Nitrous oxide has very different effects however, and even at low doses includes auditory distortions. Unlike with many other psychedelic chemicals, salvia users are generally not ambulatory and the experience is frequently dissociative. Often a very brief trance is entered, where the user experiences an intense and very realistic dream state. On the other hand, the effect of salvia on emotion has been reported to be less marked than that of true psychedelics. Binomial name Amanita muscaria (Linnaeus) Hook. ... Muscimol (agarin, pantherine) is the psychoactive compound present in Amanita muscaria and Amanita Pantherina. ... The GABA-a pentameric receptor The GABAA receptor is one of the three ligand-gated ion channels responsible for mediating the effects of Gamma-AminoButyric Acid (GABA), the major inhibitory neurotransmitter in the human body. ... Categories: Stub | Amino acids ... Muscarine, L-(+)-muscarine, or muscarin is a natural product found in certain mushrooms, particularly in Inocybe and Clitocybe species. ... Muscarinic receptors are those membrane-bound acetylcholine receptors that are more sensitive to muscarine than to nicotine. ... To meet Wikipedias quality standards, this article or section may require cleanup. ... For other uses, see LSD (disambiguation). ... It has been suggested that Feeling be merged into this article or section. ...


Although muscimol does not usually cause normal hallucinations, it has a tendency to put the user to sleep, during which the user is able to have very vivid dreams with good dream recall.
