Last month, President Bush touted the results of a government-sponsored study by the University of Michigan called Monitoring the Future. It reported a broad decline in drug use among young people since 2001. This included a 24 percent drop in the overall use of illicit drugs. There was one exception he said: abuse of painkillers. But, one important metric that wasn’t mentioned, and that stubbornly resisted the downturn, was the use of cocaine.

According to data from the group that produced the report, the percentage of both black and white 12th graders who confessed to using cocaine in the past 30 days has essentially stayed flat since 2001. The major difference is that white usage outweighs black usage 4 to 1. (If you take a longer view back to 1991, when cocaine usage bottomed out following the outrageous ’80s, usage among white 12th graders since then has nearly doubled, while usage among black 12th graders has fallen a bit.)

While we turned our attention to pills being swiped from parents’ medicine cabinets, the number of youngsters snorting white lines continued virtually unabated, producing a striking consequence.
