The FDNY hires plenty of bad boys, so what’s one more, argues a former smoke-eater who was canned after being convicted of running a Queens marijuana farm.

Patrick Murray was arrested in 2009 on charges he helped run a pot grow house in a Bell Rose home.

Murray was convicted on drug charges in 2010 but later had them overturned, after spending three years in prison. He was rejected for reinstatement to the FDNY in January and filed a Brooklyn Supreme Court petition to get his job back.

“Two of the police officers who shot and killed Amadou Diallo are now New York City firefighters,” Murray argued in papers filed Friday. “Yet the department refuses reinstatement to a decorated member . . . who served flawlessly for seven years.”

The city said it will review the petition.
