Police in Mexico have seized a record 15 tonnes of pure methamphetamine in the western state of Jalisco.
According to the UN, the record haul is twice the total amount of methamphetamine seized in Mexico in 2009.
The record seizures indicate the growing market for the deadly synthetic drug.
Mexican cartels already control the supply of marijuana, cocaine and heroine to the US and now they are vying to dominate the methamphetamine market.
But more than 80 per cent of all methamphetamine that enters the US comes from Mexico - as Mexican drug cartels increasingly use Central America as a base to traffic the drug.
