A 17-year-old drug smuggler was busted Tuesday when she tried to cross into Arizona with a load in her undies.

The Nogales, Sonora, teen was arrested as she tried to walk across the boarder with more than a pound of methamphetamine in her underwear, a Customs and Border Protection official said in a news release.

“During inspection, officers discovered a package of meth in her crotch area,” the official said.

The drugs were worth nearly $18,000.
