As the failure of the drug war in Mexico becomes increasingly difficult to deny, we’re beginning to see a change in the tone of the drug policy discussion:

The architect of Mexico's offensive against drug traffickers, President Felipe Calderon, has sent a proposal to Congress that would decriminalize small amounts of drugs by giving those consumers the choice of treatment instead of jail time. Authorities hope the change would free up resources to go after higher-level criminals.

The speaker of Mexico City's legislative assembly has gone even further, saying he wants to turn the capital into another Amsterdam by legalizing small sales of marijuana, which he calls a "soft drug" currently controlled by criminals. [Chicago Tribune]

Can you even imagine how U.S. drug warriors would react if Mexico tried to legalize marijuana sales? Move over Cuban Missile Crisis, this would really be the greatest national security nightmare in American history. I’m not kidding, because these drug war cheerleaders really are more afraid of an 1/8 ounce of marijuana than the devil himself.

But as far as Mexico is concerned, regulated marijuana sales would be frickin’ ingenious. You could de-fund a major sector of the blackmarket economy, while cashing in on massive tourism income. It would be like Amsterdam, except with delicious tacos instead of the wretched crap that passes for food in the Red Light District.
