Meth crisis moves to Mexico

Steve Suo of The Oregonian investigates America's methamphetamine crisis, now rooted in Mexico, where drug cartels are illicitly obtaining tons of pseudoephedrine, the key ingredient needed to make the potent stimulant. "Mexico's imports of the cold medicine have vaulted from 66 tons to 224 tons in the past five years, customs records show. That's roughly double what the country needs to meet the legitimate demands of cold and allergy sufferers," an analysis by The Oregonian found. This story follows a five-part special investigation by The Oregonian titled Unnecessary Epidemic that ran in October.
