A pink holiday package with a Lego Ninjago toy box inside it seemed normal enough at first glance, but when authorities took a closer look they learned the package contained molly and ecstasy.

The drugs were just a small portion of nearly 45 kilos of molly — powdered MDMA — and ecstasy that have been seized at an international mail facility in Jersey City since October, federal authorities announced Wednesday morning.

Officials from U.S. Customs and Border Protection (CBP) and Homeland Security Investigations (HSI) told reporters the drugs that have been seized at the International Bulk Mail and Distribution Center in Jersey City off County Road have a street value of nearly $800,000. Authorities said the drugs were shipped into the United States primarily from Germany, Netherlands and Belgium, among other European countries, authorities said.

“If you’re going to import illegal narcotics into the United States through the port of New York and Newark, we’re going to find it, and we’re going to seize it,” Stephen Maloney, the CBP’s acting port director for the Port of New York/Newark, said.

CBP has seen a “significant uptick” in molly and ecstasy seizures, Maloney said, noting that the agency has already seized more drugs this fiscal year (since Oct. 1.) than it did during the entire previous fiscal year.

Maloney attributed the uptick in seizures to increased screening at international mail facilities and upcoming spring breaks, noting that these party drugs appeal mostly to teenagers and college students.

According to the National Survey on Drug Use and Health, more than 18 million people in the United States have tried MDMA at least once in their lifetime.

The drugs — which come in powder and pill forms — are typically sent to the U.S. from Europe in vacuum-sealed bags and are usually concealed within toys, candy and other food products, federal authorities said.

“Today’s teens and young adults get MDMA, but now it’s mixed with other chemicals. It’s adulterated with things such as fentanyl,” HSI Special Agent in Charge Brian Michael said.

“Young people are taking pills believing it’s MDMA, when in fact it not. That’s why the efforts we’re undertaking here are so vitally important."
