The Canada Border Services Agency is revealing details of a drug seizure at the Port of Halifax months after it happened.

The CBSA says officers seized four kilograms of what it suspected was the anesthetic ketamine on February 11th.

The agency says it was found in a shipment from India containing natural health products.

“The suspected ketamine appeared to be dissolved in containers of liquid,” said a news relesae from CBSA. “Field tests conducted on bottles within the shipment indicated the presence of ketamine, which was later confirmed by the CBSA laboratory. ”

Ketamine is an anesthetic that’s used as a hallucinogenic street drug called “Special K.” Rapists have also been known to use it on victims to sedate them and stop them from resisting.

The goods were seized and turned over to the Ports Enforcement Team which includes RCMP and Halifax Regional Police.
