The Imps have provided Specialist Detector Dogs Ltd with a training venue in recent weeks.
City have teamed up with the Lincoln-based company to offer them the LNER Stadium as a place to train their detection dogs.
As part of the detector dogs’ training programme, they will be in attendance at some home fixtures between now and the end of the season.
City’s safety officer Rob Bradley said: "We take spectator welfare seriously and have recently adopted our own drugs policy, which is in line with the EFL’s campaign to tackle drug misuse in stadiums.
"Unfortunately, drug misuse is a problem which affects football as well as society.
"Our partnership with Lincoln based Specialist Detector Dogs is just one way the club is working hard to ensure that all visitors to the LNER Stadium can have a safe and enjoyable matchday experience."
