In March 1992, the Child Welfare League of America releases a survey linking the drug epidemic (crack-cocaine) to the 50 percent increase in foster care over the previous five years. The survey of several states and agencies found that of 305,716 children served in the previous year, 36.8 percent were from families in which there was an alcohol- or drug-abusing caregiver or were themselves alcohol or drug abusers. Private agencies and CPS workers indicated an even higher percentage.
