Completely fictional creatures invented in the 1980's by the
Church of Voodoo Pharmacology. The allegation was that crack cocaine smoked by pregnant women essentially caused
fetal alcohol syndrome, when in fact (as many doctors have
testified), the often-freakish babies born to crack addicts were the victims of serious malnutrition (as their mothers were often very poor and/or retarded) and of course fetal alcohol syndrome.
For absurd definitions see crack baby.
Interviewer: Tell us about the crack baby
plague which is sweeping the nation.
Doctor: Actually, on examining these "crack babies," I find that their mothers were almost always alcholics and chain-smokers who were seriously
malnourished during pregnancy. Any fetus would be extremely lucky to end up normal in that situation, with or without cocaine.
Interviewer: No, you're not getting the concept. We want to know about the *plague* of *crack babies*. If you won't
cooperate we'll just interview someone else.
