This is something else we have failed at and need to rethink in a major way.
From the piece:
The direct monetary cost to American taxpayers of the war on drugs includes spending on police, the court personnel used to try drug users and traffickers, and the guards and other resources spent on imprisoning and punishing those convicted of drug offenses. Total current spending is estimated at over $40 billion a year.
These costs don't include many other harmful effects of the war on drugs that are difficult to quantify. For example, over the past 40 years the fraction of students who have dropped out of American high schools has remained large, at about 25%. Dropout rates are not high for middle-class white children, but they are very high for black and Hispanic children living in poor neighborhoods. Many factors explain the high dropout rates, especially bad schools and weak family support. But another important factor in inner-city neighborhoods is the temptation to drop out of school in order to profit from the drug trade.
