A completely fictional creature 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.
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.
