    UNITED STATES of America, Plaintiff-Appellee, v. Kemo DOWE, Defendant-Appellant.
    No. 12-15605
    Non-Argument Calendar.
    United States Court of Appeals, Eleventh Circuit.
    Nov. 6, 2013.
    Yvette Rhodes, Robert E. O’Neill, U.S. Attorney’s Office, Tampa, FL, Emmett Jackson Boggs, U.S. Attorney’s Office, Orlando, FL, for Plaintiff-Appellee.
    Dane K. Chase, Tim Bower Rodriguez, Tim Bower Rodriguez, PA, Tampa, FL, for Defendant-Appellant.
    
      Before HULL, JORDAN, and EDMONDSON, Circuit Judges.
   PER CURIAM:

Kemo Dowe appeals his 240-month, mandatory minimum sentence, imposed after he pleaded guilty to one count of conspiring to distribute and possess with intent to distribute cocaine, cocaine base, marijuana, 4-Methylenedioxymethamphe-tamine (“MDMA”), and N-Benzylpipera-zine (“BZP”), in violation of 21 U.S.C. §§ 841(a)(1), (b)(l)(A)(iii), (b)(1)(C); and 846. In this appeal and for the first time, Dowe argues that the sentence (which was enhanced due to a prior cocaine conviction) constitutes cruel and unusual punishment.

For an error to be plain, it must be “contrary to explicit statutory provisions or to on-point precedent in this Court or the Supreme Court.” United States v. Hoffman, 710 F.3d 1228, 1281-32 (11th Cir.2013). The district court did not commit plain error. This Court’s precedent has established the validity of mandatory minimum sentences imposed based on pri- or convictions. And Dowe failed to show that his sentence was grossly disproportionate. For background, see United States v. Lopez, 649 F.3d 1222, 1248 (11th Cir.2011); United States v. Farley, 607 F.3d 1294 (11th Cir.2010); United States v. Brant, 62 F.3d 367 (11th Cir.1995).

AFFIRMED.
