Albert Hillaire appeals from an order of the district court denying his motion to vacate judgment and sentence filed pursuant to 28 U.S.C. § 2255. 1 We affirm.

On November 28, 1966 the appellant pleaded guilty to conspiracy to import, receive, conceal, sell and facilitate the transportation of some 2400 pounds of *129 marihuana, in violation of 21 U.S.C. § 176a. He now contends that his guilty plea was not freely and understandingly entered because it was induced by the presumption stated in § 176a. The provision of § 176a which allowed a jury to infer knowledge of illegal importation from the fact of possession was held unconstitutional in Leary v. United States, 395 U.S. 6, 89 S.Ct. 1532, 23 L.Ed.2d 57 (1969).

Leary is not applicable because this case was not tried and the presumption invalidated in Leary was not used. The plea of guilty by appellant was an admission of the facts presumed under § 176a; and under that plea he waived all non-jurisdictional issues or objections. Mejia v. United States, 430 F.2d 1273 (5th Cir. 1970); Cooper v. Holman, 356 F.2d 82 (5th Cir. 1966); Busby v. Holman, 356 F.2d 75 (5th Cir. 1966).

Affirmed.
