The number of international parcels that contain drugs increased to 316 during the first half of this year from 176 over the same period last year. “People can now directly purchase drugs online,” the Korea Customs Service said in a statement. “That affected the increasing number of international parcels that are used to smuggle illegal drugs,” it said. Methamphetamine took up the highest portion at 60.1 kilograms. The customs office says that the amount of meth seized could have been used by 2 million people. The office said the type of narcotics brought into Korea was diversifying, with marijuana and cocaine growing in popularity. The Korea Customs Service vowed to strengthen infrastructure to increase detection of smuggled drugs from different channels. It will especially focus on parcels that come from locations where drugs that are illegal in Korea are legalized.
