Mexican troops seized 15 tons of methamphetamine in a western state of Mexico, the Associated Press reported Thursday, which if sold in the U.S. would be worth $4 billion.

That is a lot of meth! The AP says, in fact, this is likely the biggest meth seizure ever made. After receiving anonymous tips, the troops found barrels of pure meth powder on a ranch in the state of Jalisco. (You can see them above.) They found no one there and made no arrests, but a U.S. official says it probably belonged to the Sinaloa cartel, a powerful group in the region. Sources said that the amount seized was so large that the U.S. could expect a real disruption in its supply, so it'll be interesting to hear if shortages do in fact crop up.
