Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
Stimulant psychosis is a mental disorder characterized by psychotic symptoms (such as hallucinations, paranoid ideation, delusions, disorganized thinking, grossly disorganized behaviour). It involves and typically occurs following an overdose or several day binge on psychostimulants , [ 1 ] although it can occur in the course of stimulant ...
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.
Psychoactive drugs operate by temporarily affecting a person's neurochemistry, which in turn causes changes in a person's mood, cognition, perception and behavior. There are many ways in which psychoactive drugs can affect the brain. Each drug has a specific action on one or more neurotransmitter or neuroreceptor in the brain.
That does have psychoactive properties but can also cause a “nasty” experience if processed improperly in the body, according to a Canadian company working on muscimol’s therapeutic potential.
Although serotonin itself is non-hallucinogenic, at very high concentrations achieved pharmacologically (e.g., injected into the brain or with massive doses of 5-HTP) it can produce psychedelic-like effects in animals by being metabolized by indolethylamine N-methyltransferase (INMT) into more lipophilic N-methylated tryptamines like N ...
The related lysergamide lysergic acid amide (LSA) that lacks the diethylamide moiety is far less hallucinogenic in comparison. [128] LSD, like other psychedelics, has been found to increase the expression of genes related to synaptic plasticity. [129] This is in part due to binding to brain-derived neurotrophic factor (BDNF) receptor TrkB. [130]
While there are many types of psychosis, the cause of substance-induced psychosis can be pinpointed to intake of specific chemicals. To properly diagnose Substance-Induced Psychotic Disorder, one must conclude that exhibited hallucinations or delusions began during intoxication, withdrawal, or within a month after use of the substance and the ...
