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.    This is usually manifested through recklessness, poor risk assessment, and a disregard for social conventions.
At its lower levels of intensity, disinhibition can allow one to overcome emotional apprehension and suppressed social skills in a manner that is moderated and controllable for the average person. This can often prove useful for those who suffer from social anxiety or a general lack of self-confidence.
However, at its higher levels of intensity, the disinhibited individual may be completely unable to maintain any semblance of self-restraint, at the expense of politeness, sensitivity, or social appropriateness. This lack of constraint can be negative, neutral, or positive depending on the individual and their current environment.
Disinhibition is often accompanied by other coinciding effects such as amnesia and anxiety suppression in a manner which can further decrease the person's observance of and regard for social norms. It is most commonly induced under the influence of moderate dosages of GABAergic depressants, such as alcohol  , benzodiazepines  , phenibut, and GHB. However, it may also occur under the influence of certain stimulants  , entactogens  , and dissociatives  .
