The drugs were found in a house in Pedro Juan Caballero, a city bordering Brazil, Xinhua cited from a report by the Paraguay’s National Anti-Drug Secretariat.
Authorities said Thursday the house was used as a warehouse before the drugs were sent to Brazil.
Police also confiscated 1.1 kg of cocaine. Although no one was in the house at the time of the operation, police found evidence that could lead to those responsible, said the report.
Pedro Juan Caballero, located 536 km northeast of Asuncion, is the capital city of Paraguay’s department of Amambay, bordering the Brazilian city of Ponta Pora.
Paraguay is the world’s second largest producer of marijuana, according to official figures.
