This effect is most commonly induced under the influence of moderate dosages of depressant and dissociative compounds, such as alcohol, quetiapine, ketamine, and DXM.

Respiratory depression can be described as a reduced urge to breathe that can be fatal depending on its intensity. It is most commonly induced under the influence of heavy dosages of depressant compounds, particularly opioids, such as heroin and fentanyl, or GABAergics, such as alcohol and GHB. However, it is worth noting that otherwise safe dosages of these compounds can become fatal when combined with even small amounts of other classes of depressant.

Dizziness can be described as the perception of a spinning or swaying motion which typically causes a difficulty in standing or walking. It is most commonly induced under the influence of heavy dosages of GABAergic depressant compounds, such as benzodiazepines, alcohol, and GHB.

Motor control loss can be described as feeling as if there has been a distinct decrease in a person's ability to control their physical body with precision, balance, coordination, and dexterity. Motor control loss is often accompanied by other coinciding effects such as sedation and disinhibition. It is most commonly induced under the influence of moderate dosages of GABAergic depressant compounds, such as, alcohol, benzodiazepines, GHB, and phenibut.

Muscle relaxation can be described as the experience of muscles losing their rigidity or tenseness while becoming relaxed and comfortable. It is most commonly induced under the influence of moderate dosages of depressant compounds, such as various benzodiazepines, GABAergics, and opioids.

Sedation can be described as a decrease in a person's physical energy levels which are interpreted as discouraging when it comes to wakefulness, movement, performing tasks, talkativeness, and general exercise. It is most commonly induced under the influence of moderate dosages of depressant compounds, such as opioids, GABAergics, and antipsychotics.

An auditory hallucination is the experience of hearing spontaneous and imaginary noises. They are most commonly induced under the influence of moderate dosages of hallucinogenic compounds, such as psychedelics, deliriants, and dissociatives.

It is most commonly induced under the influence of heavy dosages of GABAergic depressants, such as alcohol, benzodiazepines, GHB, and zolpidem.

Analysis suppression is a distinct decrease in a person's overall ability to process information and logically or creatively analyze concepts, ideas, and scenarios. It is most commonly induced under the influence of heavy dosages of antipsychotic compounds, and is associated with long term use of such drugs like quetiapine, haloperidol, and risperidone.

Anxiety suppression (also known as anxiolysis or minimal sedation) is medically recognized as a partial to complete suppression of a person’s ability to feel anxiety, general unease, and negative feelings of both psychological and physiological tension. It is most commonly induced under the influence of moderate dosages of anxiolytic compounds which primarily include GABAergic depressants, such as benzodiazepines, alcohol, GHB, and gabapentinoids.

Compulsive redosing is the experience of a powerful and difficult to resist urge to continuously redose a psychoactive substance in an effort to increase or maintain the subjective effects which it induces. It is most commonly induced under the influence of moderate dosages of a wide variety of compounds, such as opioids, stimulants, GABAergics, and entactogens.

Delirium (also known as acute confusion) is medically recognized as a physiological disturbance of awareness that is accompanied by a change in baseline cognition which cannot be better explained by a preexisting or evolving neurocognitive disorder. The disturbance in awareness is manifested by a reduced ability to direct, focus, sustain, and shift attention and the accompanying cognitive change in at least one other area may include memory and learning (particularly recent memory), disorientation (particularly to time and place), alteration in language, or perceptual distortions or a perceptual-motor disturbance. It is most commonly induced under the influence of heavy dosages of deliriant compounds, such as DPH, datura, and benzydamine.

A delusion is a false idea or belief that is held with strong conviction and subjective certainty and is inconsistent with an individual’s educational, cultural and social background. Delusions are most commonly induced under the influence of heavy dosages of hallucinogenic compounds, such as psychedelics, deliriants, and dissociatives.

Disinhibition is medically recognized as an orientation towards immediate gratification, leading to impulsive behavior driven by current thoughts, feelings, and external stimuli, without regard for past learning or consideration of future consequences. It is most commonly induced under the influence of moderate dosages of GABAergic depressants, such as alcohol, benzodiazepines, phenibut, and GHB.

Emotion suppression (also known as flat affect, apathy, or emotional blunting) is medically recognized as a flattening or decrease in the intensity of one's current emotional state below normal levels. It is most commonly induced under the influence of moderate dosages of antipsychotic compounds, such as quetiapine, haloperidol, and risperidone.

Irritability is medically recognized as the pervasive and sustained emotional state of being easily annoyed and provoked to anger. It is most commonly induced during the after effects of heavy dosages of stimulant compounds, such as cocaine, methamphetamine, and methylphenidate.
