The amount of fentanyl seized by U.S. border agents has skyrocketed in recent years, from two pounds in fiscal year 2013 to approximately 1,485 pounds from Oct. 1, 2016, to Sept. 30, 2017, according to federal data published Tuesday.

Customs and Border Protection reported finding 2.14 million pounds of drugs — including 5,760 pounds of heroin, 66,617 pounds of methamphetamine, and 273,580 pounds of cocaine. Officers also seized 1.59 million pounds of marijuana, the report stated.

The Department of Homeland Security agency did not put an estimated value of the narcotics found on individuals and their property.

The majority of illicit drug smuggling took place on the Southwest border between the U.S. and Mexico. CBP officials said they are seeing a growing number of synthetic, or designer, drugs being smuggled into the country through international mail and express consignment carriers.

The agency also seized more than $96.8 million in unreported currency, 2,302 firearms, and 305,414 rounds of ammunition.
