Cocaine inside sharks. 12,000 gallons of ephedrine.

The scale (and the economics) of world recreational drug trade is underscored by two discoveries in Mexico:

The Mexican Navy says it has seized more than a tonne of cocaine hidden inside the carcasses of frozen sharks.

Armed officers found slabs of cocaine inside more than 20 sharks aboard a freight ship in the Gulf coast port of Progreso in Yucatan state...

In another development... two enormous sheds where investigators found 12,905 gallons (49,640 litres) of ephedrine, a chemical used to make methamphetamine.

Officials said it was enough to produce 40.2 tonnes of the drug, or about 309 million individual doses.
