Just Say No to the War on Drugs

Ted Cruz recently asserted that the United States military needs to be sent to Mexico to attack the drug cartels head-on. This is a bad idea. But so is the drug war itself, both constitutionally and logically. Many who support the war do so with the best of intentions, but has it really helped? Or has it done more harm than good, like the Prohibition of the 1920s? Is this war even legal in the first place?

James Harrigan and Antony Davies discuss these questions in this week's Words and Numbers.
