This has come as embarrassment for North Korea as its supreme leader failed to practice what his government is preaching.
North Korea's state media published a photograph this week of Kim holding a cigarette in his hand -- with smoke permeating from the tip -- in the middle of a North Korea anti-smoking drive.
He was caught doing so while providing field guidance to the remodeled Mangyongdae Children's Camp," in the capital Pyongyang, CNN reported citing KCNA news agency.
The anti-smoking campaign was first reported by KCNA in May.
Kim Jong-Un earlier banned his aides and officials from smoking foreign cigarettes because they are unpatriotic.
