The good news: The crackdown on methamphetamine in the U.S. is working.

The bad news: Mexican drug cartels are fulfilling the demand by pumping out cheap, potent meth from so-called “superlabs,” the Associated Press reports.

“These are sophisticated, high-tech operations in Mexico that are operating with extreme precision,” said Jim Shroba, a DEA agent in St. Louis. “They’re moving it out the door as fast as they can manufacture it.”

Meth coming from Mexico now accounts for 80% of the drug being sold in the U.S., according to the DEA.

And it’s more enticing then ever – purer, faster, strong and longer-lasting.
