13 pounds of date-rape drug seized at Washington Dulles International Airport

WASHINGTON (FOX 5 DC) - U.S. Customs and Border Protection officers seized five bottles of a date-rape drug Monday that arrived through international mail from China to Washington Dulles International Airport. 

A package with five white, unlabeled, plastic bottles full of gamma-butyrolactone (GBL) were discovered during an inspection, according to officers. 

They said the package, which weighed more than 13 pounds, was headed to an address in Los Angeles. 

GBL is an odorless, colorless, central nervous system depressant that has addictive properties and potentially severe health consequences, according to the Drug Enforcement Administration. Sexual predators have used the substance as a date-rape drug.
