    UNITED STATES of America, Plaintiff-Appellee, v. Rikky Alan JOHNSON, Defendant-Appellant.
    No. 10-10316
    Non-Argument Calendar.
    United States Court of Appeals, Eleventh Circuit.
    Sept. 9, 2010.
    A. Brian Albritton, David Paul Rhodes, U.S. Attorney’s Office, Shauna S. Hale, Asst. U.S. Attorney — U.S. Attorney’s Office, Tampa, FL, for Plaintiff-Appellee.
    Mark J. O’Brien, O’Brien Bower, PA, Tampa, FL, for Defendant-Appellant.
    Before BLACK, CARNES and PRYOR, Circuit Judges.
   PER CURIAM:

Rikky Alan Johnson appeals his 60-month sentence for possession with intent to distribute 5 grams or more of cocaine base, in violation of 21 U.S.C. § 841(a)(1) and (b)(l)(B)(iii). He concedes that the sentence he received is the statutory mandatory minimum required by § 841(b)(l)(B)(iii) but contends that the statute is unconstitutional because the sentencing disparity between cases involving powder cocaine and those involving crack cocaine, which is effected by the statute, violates equal protection principles. The parties disagree about whether Johnson properly preserved this issue in the district court, but that does not matter.

Under 21 U.S.C. § 841(b)(l)(B)(iii), a defendant who is convicted of possessing with intent to distribute at least five grams of a mixture or substance containing crack cocaine must be sentenced to at least five years’ imprisonment. A defendant must be convicted of possessing with intent to distribute at least 500 grams of a mixture or substance containing powder cocaine to be subject to the 5-year mandatory minimum. 21 U.S.C. § 841(b)(l)(B)(ii). “[T]he district court remains bound by statutes designating mandatory minimum sentences even after the remedial holding of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005).” United States v. Castaing-Sosa, 530 F.3d 1358, 1362 (11th Cir.2008).

We have held that the sentencing disparity between crack cocaine and powder cocaine offenses created by the enactment of § 841 does not violate the Equal Protection Clause, even though the statute has a disparate impact. United States v. Byse, 28 F.3d 1165, 1168-70 (11th Cir.1994); United States v. King, 972 F.2d 1259, 1260 (11th Cir.1992) (holding that a disparate impact alone was insufficient to establish an equal protection violation and that § 841 was subject to rational-basis review); see also United States v. Butler, 102 F.3d 1191, 1194-95 (11th Cir.1997) (holding that the 100:1 sentencing disparity between crack cocaine and powder cocaine offenses in the Sentencing Guidelines does not violate a defendant’s equal protection rights). Furthermore, in addressing the enactment of § 841, we have held that, under rational-basis review, “[t]he fact that crack cocaine is more addictive, more dangerous, and can be sold in smaller quantities than powder cocaine is sufficient reason for Congress to provide harsher penalties for its possession.” King, 972 F.2d at 1260; Byse, 28 F.3d at 1170-71. We remain bound by those prior panel precedents. See United States v. Vega-Castillo, 540 F.3d 1235, 1236 (11th Cir.2008), cert. denied, — U.S. -, 129 S.Ct. 2825, 174 L.Ed.2d 556 (2009) (quotation omitted).

AFFIRMED.
