Mumbai: With the Narcotics Control Bureau (NCB) cracking down on courier companies delivering parcels without checking, drug peddlers and dealers have begun to turn to the postal service to send the contraband.

"Of late, a trend has emerged that the peddlers and dealers send their contraband through post offices. To evade the law enforcement agencies dealers bring huge quantity of contraband to Mumbai and send them to other places through EMS speed post," a senior NCB official said, requesting anonymity.
