The focus of the drug war in the United States has shifted significantly over the past decade from hard drugs to marijuana, which now accounts for nearly half of all drug arrests nationwide, according to an analysis of federal crime statistics released yesterday.
The study of FBI data by a Washington-based think tank, the Sentencing Project, found that the proportion of heroin and cocaine cases plummeted from 55 percent of all drug arrests in 1992 to less than 30 percent 10 years later. During the same period, marijuana arrests rose from 28 percent of the total to 45 percent.
Coming in the wake of the focus on crack cocaine in the late 1980s, the increasing emphasis on marijuana enforcement was accompanied by a dramatic rise in overall drug arrests, from fewer than 1.1 million in 1990 to more than 1.5 million a decade later. Eighty percent of that increase came from marijuana arrests, the study found.
The rapid increase has not had a significant impact on prisons, however, because just 6 percent of the arrests resulted in felony convictions, the study found. The most widely quoted household survey on the topic has shown relatively little change in the overall rate of marijuana use over the same time period, experts said.
