Ruffin, Judge.
After a bench trial, the trial court found Roger Willie Harris guilty of possession of drugs by an inmate in a correctional institute (OCGA § 42-5-18 (b)) and possession of marijuana (OCGA § 16-13-30). Harris appeals. For the following reasons, we dismiss this appeal for lack of jurisdiction.
In two enumerations of error, Harris argues that OCGA §§ 42-5-18 (b) and 16-13-21 (16) are unconstitutionally vague. Each of these enumerations raises the question of our jurisdiction to consider this appeal. Except in limited situations, not here pertinent, the Supreme Court has exclusive jurisdiction of constitutional construction. See Ga. Const, of 1983, Art. VI, Sec. VI, Par. II (1). In this instance, the record does not show that the trial court ever ruled on Harris’ challenge to the constitutionality of either statute. Nor does the record reveal that Harris elicited any ruling on this issue. Since there is no ruling on the constitutionality of either statute, “[t]he issue is not *843properly presented for appellate review in this case . . . as it was not explicitly argued and ruled on below.” Brantley v.
