Homeless addicts, crack babies, drive-by-shootings, gangs, burglaries, robberies, muggings, black-on-black youth violence. Where did this scourge come from?

The twin centers of the crack cocaine industry are Los Angeles and Miami. The first time the MIAMI HERALD ever mentioned crack cocaine was April 20, 1986.[1] The first time the LOS ANGELES TIMES ever mentioned crack cocaine was two months later on June 30, 1986.[2] The news service Facts on File first mentioned crack on August 15, 1986, under the headline, "'Crack' Explosion Alarms Nation."[3] That story said crack had been around for "as long as 3 years, but its use was said to have exploded in the last months of 1985 and the first half of 1986." From these sources, we conclude that crack first appeared about 1983 and began spreading quickly; by mid-1986, it was a nationwide problem. What happened between 1983 and 1986?

Cocaine had been around as a sniffable white powder since the mid-1970s, but it cost $200 a gram ($5600 an ounce) providing recreation for the rich, not for working people. But by 1986 that had changed. The MIAMI HERALD wrote April 20, 1986, "Described until recently as a rich man's drug, cocaine has filtered down to blue-collar households and is finding an eager market among high school students who can ante up $10 or so to buy some 'crack,' cocaine in a highly purified form suitable for free-basing [smoking]."[1] The LOS ANGELES TIMES wrote September 21, 1986, "The economics of cocaine have changed so radically that it is no longer restricted to the well-to-do. The processing of crystallized cocaine as 'rock' or 'crack' has so lowered the price--and increased the availability--that junior high school students are pooling their lunch money... to buy cocaine from schoolyard dealers."[4] How did crack spread throughout urban neighborhoods during 1983-1986?
