Defendant’s sole point on appeal from his conviction under 21 U.S.C. § 173 is that the trial court improperly permitted the use of evidence of defendant’s prior convictions for impeachment. Defendant relies upon the line of cases following Luck v. United States, 121 U.S.App. D.C. 151, 348 F.2d 763 (1965). Since no objection was made to the evidence, its use was not reversible error. Hood v. United States, 125 U.S.App.D.C. 16, 365 F. 2d 949, 951 (1966).

Affirmed.
