The illicit uses of anti- anxiety drugs both stem from a basic anxiety and simultaneously exist outside of it. Anti- anxiety drugs are drugs that significantly slow down the effects of the nervous system. The need to reduce tension, enable consciousness to be "more bearable," and to placate a perceived or not understood weakness within the individual are all a part of the illicit use of the drugs. Illicit use of the anti- anxiety drug gamma hydroxybutyrate or GHB has been seen through the use of anabolic steroids and those driven by an ideal of fitness or of physical stature. Flunitrazepam or Rohypnol has become the "date rape" drug as a result of its inducing of amnesia by those who conceive it. Its illicit use has been perpetrated by sexual crime offenders as it enables perpetrators to sexually violate their victims while those who are victimized by it have no memory of what happened. The illicit uses of Ketamine are to achieve a high or hallucinatory effect in the user. Finally, an overall illicit use of anti-anxiety drugs is the mixing of these depressants with stimulants to create a heightened effect in the user.
