Cost = $1 trillion and lots of lives

That's what the Associated Press has computed as the cost of our drug war over the past 40 years. What has been the result of that investment? Here's what AP says in its conclusion to what appears to be a fairly in-depth study of the issue:

_ $20 billion to fight the drug gangs in their home countries. In Colombia, for example, the United States spent more than $6 billion, while coca cultivation increased and trafficking moved to Mexico — and the violence along with it.

_ $33 billion in marketing "Just Say No"-style messages to America's youth and other prevention programs. High school students report the same rates of illegal drug use as they did in 1970, and the Centers for Disease Control and Prevention says drug overdoses have "risen steadily" since the early 1970s to more than 20,000 last year.

_ $49 billion for law enforcement along America's borders to cut off the flow of illegal drugs. This year, 25 million Americans will snort, swallow, inject and smoke illicit drugs, about 10 million more than in 1970, with the bulk of those drugs imported from Mexico.

_ $121 billion to arrest more than 37 million nonviolent drug offenders, about 10 million of them for possession of marijuana. Studies show that jail time tends to increase drug abuse.

_ $450 billion to lock those people up in federal prisons alone. Last year, half of all federal prisoners in the U.S. were serving sentences for drug offenses.

At the same time, drug abuse is costing the nation in other ways. The Justice Department estimates the consequences of drug abuse — "an overburdened justice system, a strained health care system, lost productivity, and environmental destruction" — cost the United States $215 billion a year.

Harvard University economist Jeffrey Miron says the only sure thing taxpayers get for more spending on police and soldiers is more homicides.

Yet despite what it says about the drug war, the administration continues to spend twice as much on the war as it spends on prevention.
