AB Drug  abuse  is  usually  taken  to  mean  the  use  of  an  illicit  drug  or  the  excessive  or  nonmedical  use  of  a  licit  drug.  It  also  denotes  the  deliberate  use  of  chemicals  that  generally  are  not  considered  drugs  by  the  lay  public  but  may  be  harmful  to  the  user.  A  primary  motivation  for  drug  abuse  appears  to  be  the  anticipated  feeling  of  pleasure  derived  from  the  CNS  effects  of  the  drug.  The  older  term  “physical  (physiologic)  dependence”  is  now  generally  denoted  as  dependence,  whereas  “psychological  dependence”  is  more  simply  called  addiction.
