Focus suppression (also known as distractability) is medically recognized as a decreased ability to selectively concentrate on an aspect of the environment while ignoring other things. It can be best characterized by feelings of intense distractability which can prevent one from focusing on and performing basic tasks that would usually be relatively easy to not get distracted from. This effect will often synergize with other coinciding effects such as motivation suppression, thought deceleration, and sedation.
Focus suppression is often accompanied by other coinciding effects such as sedation, motivation suppression, and creativity suppression. It is most commonly induced under the influence of moderate or heavy dosages of antipsychotics, benzodiazepines, cannabinoids, and hallucinogens. However, it is worth noting that stimulant compounds which primarily induce focus enhancement at light to moderate dosages will also often lead into focus suppression at their heavier dosages.
