Amnesia is a global impairment in the ability to acquire new memories regardless of sensory modality, and a loss of some memories, especially recent ones, from the period before amnesia began. 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.

Cognitive euphoria (semantically the opposite of cognitive dysphoria) is medically recognized as a cognitive and emotional state in which a person experiences intense feelings of well-being, elation, happiness, excitement, and joy. It is most commonly induced under the influence of moderate dosages of opioids, entactogens, stimulants, and GABAergic depressants. However, it can also occur to a lesser extent under the influence of hallucinogenic compounds such as psychedelics, dissociatives, and cannabinoids.

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.

Confusion is an impairment of abstract thinking demonstrated by an inability to think with one’s customary clarity and coherence. It is most commonly induced under the influence of heavy dosages of hallucinogenic compounds, such as psychedelics, dissociatives, synthetic cannabinoids, and deliriants.

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.

Dream potentiation is an effect that increases the subjective intensity, vividness, and frequency of sleeping dream states. It is most commonly induced under the influence of moderate dosages of oneirogenic compounds, a class of hallucinogen that is used to specifically potentiate dreams when taken before sleep.

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.

Language suppression is the decreased ability to use and understand speech. It is most commonly induced under the influence of heavy dosages of antipsychotic compounds, such as quetiapine, haloperidol, and risperidone.

Memory suppression is an inhibition of a person's ability to maintain a functional short and long-term memory. It is most commonly induced under the influence of moderate dosages of hallucinogenic compounds, such as psychedelics, dissociatives, and deliriants.

Motivation suppression (also known as avolition or amotivation) is a decreased desire to initiate or persist in goal-directed behavior. It is most commonly induced under the influence of an acute dosage of an antipsychotic compound, such as quetiapine, haloperidol, and risperidone. However, it is worth noting that chronic treatment with any dose of antipsychotic medication does not cause this effect.

Thought deceleration is the process of thought being slowed down significantly in comparison to that of normal sobriety. It is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics, antipsychotics, and opioids.

Physical euphoria can be described as feelings of pleasure and comfort within and across one's body. This euphoria typically feels somewhat comparable to the endorphin rushes felt during states of excitement or love, the coziness of a comfortable bed, and the rush of an orgasm. It is most commonly induced under the influence of heavy dosages of a wide variety of compounds, such as opioids, stimulants, psychedelics, and GABAergics.

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.

Decreased heart rate or bradycardia can be described as a heart rate that is lower than the normal heart rate at rest. It is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics, and opioids.

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.

Perception of bodily heaviness can be described as feeling as if one's body has significantly increased in its weight. This can result in feelings of slowness and sluggishness due to the body seeming difficult, uncomfortable, or impossible to move. It is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics, opioids, and antipsychotics.

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.

Seizure suppression is an effect caused by drugs known as "anticonvulsants". These drugs prevent or reduce the severity and frequency of seizures in various types of epilepsy. It is most commonly induced under the influence of moderate dosages of certain GABAergic compounds and certain cannabinoids.
