This state of mind is commonly referred to as a "blackout", an experience that can be divided into 2 formal categories, "fragmentary" blackouts and "en bloc" blackouts.<ref>Fragmentary and en bloc blackouts: similarity and distinction among episodes of alcohol-induced memory loss | https://www.ncbi.nlm.nih.gov/pubmed/12921196</ref> Fragmentary blackouts, sometimes known as "brownouts", are characterized by having the ability to recall specific events from an intoxicated period but remaining unaware that certain memories are missing until reminded of the existence of those 'gaps' in memory. Studies suggest that fragmentary blackouts are far more common than "en bloc" blackouts.<ref>Experiential aspects of alcohol-induced blackouts among college students. | https://www.ncbi.nlm.nih.gov/pubmed/15083562</ref> In comparison, En bloc blackouts are characterized by a complete inability to later recall any memories from an intoxicated period, even when prompted. It is usually difficult to determine the point at which this type of blackout has ended as sleep typically occurs before this happens.<ref>Alcoholic "blackouts": a review and clinical study of 100 alcoholics | https://www.ncbi.nlm.nih.gov/pubmed/5804804</ref> | This state of mind is commonly referred to as a "blackout", an experience that can be divided into 2 formal categories, "fragmentary" blackouts and "en bloc" blackouts.<ref>Fragmentary and en bloc blackouts: similarity and distinction among episodes of alcohol-induced memory loss | https://www.ncbi.nlm.nih.gov/pubmed/12921196</ref> Fragmentary blackouts, sometimes known as "brownouts", are characterized by having the ability to recall specific events from an intoxicated period but remaining unaware that certain memories are missing until reminded of the existence of those 'gaps' in memory.

It is most commonly induced under the influence of [[dosage#heavy|heavy]] [[dosage|dosages]] of [[GABAergic]] [[depressant]] compounds, such as [[alcohol]], [[benzodiazepines]], [[GHB]], and [[zolpidem]]. However, it can also occur to a much lesser extent under the influence of very heavy dosages of [[hallucinogen|hallucinogenic]] compounds such as [[psychedelic|psychedelics]], [[dissociative|dissociatives]], [[Salvia divinorum]], and [[deliriant|deliriants]]. | ||
