Stephen Douglas Dare appeals his statutory mandatory minimum ten-year sentence imposed pursuant to 18 U.S.C. § 924(c) for discharging a firearm during the course of a drug trafficking crime. He contends that he was sentenced in violation of the Sixth Amendment and that the district court erred in using a preponderance of the evidence standard when it found that he discharged a firearm. We hold *636that Dare’s mandatory minimum sentence imposed through judicial factfinding utilizing a preponderance of the evidence standard does not violate the Sixth Amendment, pursuant to Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002). We affirm the judgment.
BACKGROUND
On April 23, 2003, Steven Dare met several coworkers at a local bar and he drank alcohol for several hours. He stated that he was “pretty well trashed.” His younger friend Casey arrived in the bar with a person that Dare did not know. Casey explained that this person wanted to buy some marijuana. Unbeknownst to both Dare and Casey, the buyer was a drug informant working for the Montana drug task force.
The trio of Dare, Casey, and the informant drove to Dare’s home. Dare sold the informant a bag of marijuana for $200. Dare then asked if they would like to smoke some marijuana with him, but they declined. Dare then went into the next room and brought back his loaded shotgun. Dare stated that he “didn’t want any badges coming back at me for selling drugs.” Dare handed the shotgun to his friend Casey and asked him if he wanted to shoot it outside. Casey had been at Dare’s home and had discharged the shotgun with him in the past, but, on this occasion, Casey declined to shoot the shotgun. Dare then took the shotgun to his front door, opened the door, and discharged the shotgun in the air, aiming over his wood pile.
A federal grand jury filed a four-count indictment. Counts II and III, to which Dare later plead guilty, alleged:
Count II: [That Dare] ... in furtherance of a drug trafficking crime, to-wit: possession with intent to distribute and distribution of marijuana in violation of 21 U.S.C. § 841(a)(1), did possess a firearm, to-wit: a Winchester 12-gauge pump shotgun, Defender Model, serial number L2146716, in violation of 18 U.S.C. § 924(c);
Count III: [That Dare] ... did knowingly, intentionally, and unlawfully, possess with intent to distribute and distribute controlled substances, to-wit: 12 grams or more of a mixture of substances containing marijuana, in violation of 21 U.S.C. § 841(l)(a).
The statute under which Dare was indicted on Count II, 18 U.S.C. § 924(c), provides in relevant part:
(c)(1)(A) Except to the extent that a greater minimum sentence is otherwise provided by this subsection or by any other provision of law, any person who, during and in relation to any crime of violence or drug trafficking crime (including a crime of violence or drug trafficking crime that provides for an enhanced punishment if committed by the use of a deadly or dangerous weapon or device) for which the person may be prosecuted in a court of the United States, uses or carries a firearm, or who, in furtherance of any such crime, possesses a firearm, shall, in addition to the punishment provided for such crime of violence or drug trafficking crime—
(i) be sentenced to a term of imprisonment of not less than 5 years;
(ii) if the firearm is brandished, be sentenced to a term of imprisonment of not less than 7 years; and
(iii) if the firearm is discharged, be sentenced to a term of imprisonment of not less than 10 years.
(e)(1)(B) If the firearm possessed by a person convicted of a violation of this subsection—
(i) is a short-barreled rifle, short-barreled shotgun, or semiautomatic assault *637weapon, the person shall be sentenced to a term of imprisonment of not less than 10 years; or
(ii) is a machinegun or a destructive device, or is equipped with a firearm silencer or firearm muffler, the person shall be sentenced to a term of imprisonment of not less than BO years.
(c)(1)(C) In the case of a second or subsequent conviction under this subsection, the person shall—
(i) be sentenced to at term of imprisonment of not less than 25 years; and
(ii) if the firearm involved is a machine-gun or a destructive device, or is equipped with a firearm silencer or firearm muffler, be sentenced to imprisonment for life.
18 U.S.C. § 924(c)(l)(A)-(C) (2004).
Neither “brandishing]” nor “discharging]” the firearm, 18 U.S.C. § 924(c)(l)(A)(ii), (iii), was alleged in the indictment.
Dare entered a plea of not guilty at his arraignment. He later stated that he had no recollection of discharging the shotgun until he was informed of that fact when the magistrate judge read the indictment to Dare from the bench.
Dare moved to change his plea from not guilty to guilty. In his motion he stated:
[T]he parties have only recently recognized that under Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002), the court determines whether a sentence under 18 U.S.C. § 924(c) [Count II] should be enhanced for brandishing or discharging a firearm. ... [Defendant admits he possessed the shotgun during the drug crime but disputes that he either brandished or discharged it, which are issues for this Court at the time of sentencing under Harris, supra.
Dare acknowledged in his plea hearing that he knowingly possessed the shotgun in furtherance of the crime of possession with intent to distribute marijuana. Dare stated, when questioned by the district court, that the maximum penalty he faced under the § 924(c) charge was life imprisonment.
Dare was sentenced on April 30, 2004. Dare argued that for the government to establish that he had brandished or discharged the shotgun in relation to the drug transaction, the government had to satisfy a standard of proof beyond a reasonable doubt, or, at a minimum, a clear and convincing standard of proof. His lawyer called several witnesses, including Dare and his two. adult sons, to testify about Dare’s level of intoxication and the details regarding his use of the shotgun. Dare testified that he was highly intoxicated and that the shotgun was discharged after the drug transaction had been completed.
Regarding the sentence under § 924(c), the district court judge stated that he “had no discretion here,” and further stated:
I find it outrageous, just like his sons do, that this man, for 12 grams of marijuana, is going to spend ten years of his life in a federal prison of the United States. And at the very most, I could say, well, seven years is the best deal, and that borders on outrageous. But that’s what the law is.
You have a man who’s lived in a community for 25 years, who is recognized as hard working, honest, reliable, who would give the shirt off of his back to anybody, who has given two sons to this country to defend this country, and we’re going to lock him up for ten years and that’s not outrageous? I think it is. So I will be a part of the outrage. Unwillingly. But I’m going to do it.
*638The district court found that the government established by a preponderance of the evidence that the shotgun “was discharged in conjunction with the drug transaction.” The court also concluded, however, that “if the burden of proof is clear and convincing,” the government’s proof failed. The court noted that Dare was clearly intoxicated and was unaware that he used the gun until he was advised of that fact at his arraignment. The court found there was no clear and convincing evidence (1) that Dare had intent to intimidate or threaten the two young men with the shotgun; (2) that the two men were threatened by the discharge of the shotgun; or (8) that Dare intended the discharge of the shotgun to be a part of the drug transaction.
The district court sentenced Dare to a mandatory minimum of ten years under 18 U.S.C. § 924(c)(1)(A)(iii) for discharging a gun in conjunction with a drug transaction. The district court sentenced Dare to zero months imprisonment for the possession of marijuana.1
Dare filed a Notice of Appeal on May 6, 2004. In his brief, Dare argued that the district court should have employed a higher standard of proof at sentencing and that his sentence violated Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000) and Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). Blakely was decided by the Supreme Court in June 2004, after Dare was sentenced in April 2004.
We review de novo whether the district court applied the correct standard of proof. See United States v. Banuelos, 322 F.3d 700, 704 (9th Cir.2003). Because Dare raised his objection under Apprendi in the district court, we review his Appren-di claim de novo. See United States v. Smith, 282 F.3d 758, 771 (9th Cir.2002).
ANALYSIS
A. Sixth Amendment Protections
Dare argues that he was sentenced in violation of the Sixth Amendment constitutional protections articulated in Apprendi, then in Blakely, and most recently in United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). In Apprendi, the Court held that “[o]ther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.” Apprendi, 530 U.S. at 490, 120 S.Ct. 2348. In Blakely, the Court stated, “Our precedents make clear, however, that the ‘statutory maximum’ for Apprendi purposes is the maximum sentence a judge may impose solely on the basis of the facts reflected in the jury verdict or admitted by the defendant.”. Blakely, 124 S.Ct. at 2537 (emphasis in original). In Booker, the Court stated:
Accordingly, we reaffirm our holding in Apprendi: Any fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt.
Booker, 125 S.Ct. at 756.
The government maintains that Dare’s sentence did not violate the Sixth Amendment and should be affirmed pursuant to the holding in Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002). The defendant in Harris sold a small quantity of marijuana *639in his pawnshop with an unconcealed pistol at his side. Harris was arrested for violating drug and firearms laws, including 18 U.S.C. § 924(c)(1)(A). The indictment, similar to the indictment in this case, said nothing of “brandishing” a -firearm and made no reference to subsections of the statute. Harris was found guilty at a bench trial of knowingly carrying a firearm during and in relation to a drug trafficking crime. At sentencing, Harris disputed that he brandished the gun, just as Dare disputed that he brandished or discharged the gun in the present case. The district court in Harris found, by a preponderance of the evidence, that Harris had brandished a gun and sentenced him to seven years. Harris, 536 U.S. at 551, 122 S.Ct. 2406. Harris maintained that under Jones v. United States, 526 U.S. 227, 119 S.Ct. 1215, 143 L.Ed.2d 311 (1999) (federal carjacking statute interpreted as setting out elements of separate offenses), brandishing is a separate offense for which he had not been indicted. Harris also maintained that even if brandishing is a sentencing factor, a jury must find this factor beyond a reasonable doubt. Id.
The Court, in a plurality opinion, stated, “ § 924(c)(1)(A) defines a single offense” and “[the statute] regards brandishing and discharging as sentencing factors to be found by the judge, not offense elements to be found by the jury.” Harris, 536 U.S. at 556, 122 S.Ct. 2406. The Court distinguished Apprendi on the basis that the judge-found facts in Apprendi extended the sentence beyond the statutory maximum, while judge-found facts in Harris only increased the defendant’s minimum sentence, and did not affect the maximum sentence. Harris, 536 U.S. at 562-65, 122 S.Ct. 2406. The Harris plurality distinguished Apprendi, stating:
[O]nce the jury finds all those facts, Apprendi says that the defendant has been convicted of the crime; the Fifth and Sixth Amendments have been observed; and the Government has been authorized to impose any sentence below the maximum. That is why, as Appren-di noted, “nothing in this history suggests that it is impermissible for judges to exercise discretion — taking into consideration various factors relating both to offense and offender — in imposing a judgment within the range.” Id. at 481, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435"_[T]he judicial factfinding does not “expose a defendant to a punishment greater than that otherwise legally prescribed.” Apprendi, [530 U.S.] at 483, n. 10, 120 S.Ct. 2348.
Harris, 536 U.S. at 565, 122 S.Ct. 2406 (emphasis in original).
The Harris plurality reaffirmed the holding in McMillan v. Pennsylvania, 477 U.S. 79, 106 S.Ct. 2411, 91 L.Ed.2d 67 (1986), that a state legislature may specify the condition for a mandatory minimum sentence for possession of a firearm without making the condition an element of the crime. See Harris, 536 U.S. at 566-67, 122 S.Ct. 2406. The Harris plurality concluded:
Reaffirming McMillan and employing the approach outlined in that case, we conclude that the federal provision at issue, 18 U.S.C. § 924(c)(l)(A)(ii), is constitutional. Basing a 2-year increase in the defendant’s minimum sentence on a judicial finding of brandishing does not evade the requirements of the Fifth and Sixth Amendments. Congress “simply . took one factor that has always been considered by sentencing courts to bear on punishment ... and dictated the precise weight to be given that factor.” McMillan, 477 U.S. at 89-90, 106 S.Ct. 2411, 91 L.Ed.2d 67. That factor need not be alleged in the indictment, submit*640ted to the jury, or proved beyond a reasonable doubt.
Harris, 536 U.S. at 568, 122 S.Ct. 2406.
Dare argues that Harris should be distinguished because Harris’s minimum was increased by two years, from five to seven years, based upon the court’s determination that Harris brandished the firearm, whereas his minimum doubled from five to ten years for discharge of the firearm, thereby raising constitutional concerns. We cannot limit Harris based upon the harshness of the sentence imposed under § 924(c). The Harris plurality stated:
The Fifth and Sixth Amendments ensure that the defendant “will never get more punishment than he bargained for when he did the crime,” but they do not promise that he will receive “anything less” than that. Apprendi, [530 U.S.] at 498, 120 S.Ct. 2348 (Scalia, J., concurring). If the grand jury has alleged, and the trial jury has found, all the facts necessary to impose the maximum, the barriers between government and defendant fall. The judge may select any sentence within the range, based on facts not alleged in the indictment or proved to the jury — even if those facts are specified by the legislature, and even if they persuade the judge to choose a much higher sentence than he or she otherwise would have imposed. That a fact affects the defendant’s sentence, even dramatically so, does not by itself make it an element.
Harris, 536 U.S. at 566, 122 S.Ct. 2406.
Thus, under Harris, the district court could have sentenced Dare to any sentence within the range of five years to life without further fact finding. According to Harris, judge-found facts that increase a sentence under § 924(c) are not in the jury’s domain because the findings do not increase the possible sentence beyond the statutory maximum of life imprisonment. See Harris, 536 U.S. at 557, 578-79, 122 S.Ct. 2406 (Thomas, J., dissenting) (“[T]he constitutional analysis adopted by the plurality would hold equally true if the mandatory minimum for a violation of § 924(c)(1) .without brandishing was five years, but the mandatory minimum with brandishing was life imprisonment.”).
Justice Breyer observed in his concurring opinion in Harris that one- cannot easily distinguish Apprendi from Harris “in terms of logic.” Harris, 536 U.S. at 569, 122 S.Ct. 2406. Justice Thomas observed in his dissenting opinion in Harris that the fact that a defendant brandished a firearm “indisputably alters the prescribed range of penalties to which he is exposed under 18 U.S.C. § 924(c)(1)(A).” Harris, 536 U.S. at 575, 122 S.Ct. 2406 (Thomas, J., dissenting). Justice Thomas noted, “Whether one raises the floor or raises the ceiling it is impossible to dispute that the defendant is exposed to greater punishment than is otherwise prescribed.” Id. at 579, 122 S.Ct. 2406. He stated:
Looking to the principles that animated the decision in Apprendi and the bases for the historical practice upon which Apprendi rested (rather than the historical pedigree of mandatory mínimums), there are no logical grounds for treating facts triggering mandatory mínimums any differently than facts that increase the statutory maximum. In either case the defendant cannot predict the judgment from the face of the felony, see [Apprendi], 530 U.S. at 478-79, 120 S.Ct. 2348, 147 L.Ed.2d 435, and the absolute statutory limits of his punishment change, constituting an increased penalty.
Id. at 579-80, 122 S.Ct. 2406.
We agree that Dare could not predict his punishment from the face of his indictment or from the facts he admitted in his plea. For most sentences imposed under *641§ 924(c)(1), the minimum sentence is the maximum sentence, even though the defendant is exposed to a possible sentence as severe as life imprisonment.2 Harris, 536 U.S. at 578, 122 S.Ct. 2406 (Thomas, J., dissenting) (citing sentencing data); U.S.S.G. § 2K2.4(b). Nevertheless, we cannot distinguish the sentence imposed in Harás from the one imposed in this case.
Dare argues that the constitutional analysis in Hams was effectively overruled by the plurality in Booker, — U.S.-, 125 S.Ct. at 756, 160 L.Ed.2d 621. We agree that Hams is difficult to reconcile with the Supreme Court’s recent Sixth Amendment jurisprudence, but Harris has not been overruled. See United States v. Cardenas, 405 F.Sd 1046, 1048 (9th Cir.2005) (“Booker does not bear on mandatory mínimums.”); United States v. Jones, 418 F.3d 726, 732 (7th Cir.2005) (“Under Hams, which the Supreme Court did not disturb in Booker, imposition of the ten-year mandatory minimum sentence for violation of 924(c)(l)(A)(iii) did not violate the Sixth Amendment.”); United States v. Duncan, 413 F.3d 680, 683 (7th Cir.2005) (“[N]othing in Booker or Blakely suggests that the Court reconsidered, much less overruled, its holding in Harris.”); id. at 683 n. 3 (collecting cases from other circuits concluding that Booker does not apply to statutory mandatory minimum sentences).
We cannot question Hams’ authority as binding precedent. Hart v. Massanari, 266 F.3d 1155, 1171 (9th Cir.2001) (“A decision of the Supreme Court will control that corner of the law unless and until the Supreme Court itself overrules or modifies it. Judges of the inferior courts may voice their criticisms; but follow it they must.”); Duncan, 413 F.3d at 683-84 (“[E]ven if the logic and spirit of those decisions [Booker and Blakely ] could be interpreted to have eroded the Court’s previous rationale for permitting mandatory minimum sentences based on judicial factfinding, it certainly is not our role as an intermediate appellate court to overrule a decision of the Supreme Court or even to anticipate such an overruling by the Court.”).
B. Standard of Proof
In Harris, the Supreme Court affirmed a mandatory statutory minimum seven year sentence based upon the district court’s finding by a preponderance of the evidence that Harris had brandished a gun. Harris, 536 U.S. at 551-52, 122 S.Ct. 2406. Dare argues that because the sentencing factor of “discharging” had the “disproportionate impact” of doubling his sentence from five to ten years, the district court erred in utilizing a preponderance of the evidence standard at sentencing.3
*642As a general rule, the preponderance of the evidence standard is the appropriate standard for factual findings used for sentencing. See United States v. Howard, 894 F.2d 1085, 1089 (9th Cir.1990). However, “ ‘[W]hen a sentencing factor has an extremely disproportionate effect on the sentence relative to the offense of conviction,’ the government may have to satisfy a ‘clear and convincing’ standard.” United States v. Hopper, 177 F.3d 824, 833 (9th Cir.1999) (quoting United States v. Restrepo, 946 F.2d 654; 659 (9th Cir.1991) (en banc). In United States v. Jordan, 256 F.3d 922, 928 (9th Cir.2001), we stated that to determine a disproportionate effect, we look at the “totality of the circumstances,” including the several factors relating to disproportionate effect set forth in United States v. Valensia, 222 F.3d 1173, 1182 (9th Cir.2000), cert. granted, judgment vacated, and remanded by 532 U.S. 901, 121 S.Ct. 1222, 149 L.Ed.2d 133 (2001). These factors include: (1) whether the enhanced sentence falls within the maximum sentence for the crime alleged in the indictment; (2) whether the enhanced sentence negates the presumption of innocence or the prosecution’s burden of proof for the crime alleged in the indictment; (3) whether the facts offered in support of the enhancement create new offenses requiring separate punishment; (4) whether the increase in sentence is based on the extent of a conspiracy; (5) whether an increase in the number of offense levels is less than or equal to four; and (6) whether the length of the enhanced sentence more than doubles the length of the sentence authorized by the initial sentencing guideline range in a case where the defendant would otherwise have received a relatively short sentence. Jordan, 256 F.3d at 928 (quoting Valensia, 222 F.3d at 1182).
Dare’s argument for application of a “disproportionate impact” test would be cognizable under our case law if his sentence were imposed solely by reference to enhancements under the federal sentencing guidelines. His sentence, however, was imposed by virtue of the mandatory minimum requirements of 18 U.S.C. § 924(c). The sentencing guidelines refer to the mandatory minimum sentences under § 924(c). See U.S.S.G. § 2K2.4(b) (“[I]f the defendant, whether or not convicted of another crime, was convicted of violating section 924(c) ... the guideline sentence is the minimum term of imprisonment required by statute.”). Thus, the statutory minimum sentences in § 924(c) bind the district court, not the sentencing guidelines and enhancements.
To date, we have applied the “disproportionate impact” test only in the case of federal guideline sentencing enhancements. See United States v. Gonzalez, 365 F.3d 796, 799 (9th Cir.2004). The enhancements under the formerly mandatory federal guidelines increased the defendant’s possible maximum sentence. See Booker, — U.S. -, 125 S.Ct. at 756, 160 L.Ed.2d 621. This ease, by contrast, involves only a statutory mandatory minimum sentence. The judge’s findings did not expose Dare to a higher maximum statutory sentence, which, under Harris and the now advisory guidelines, is life imprisonment based upon the allegations in the indictment. See Harris, 536 U.S. at 565, 122 S.Ct. 2406 (“The judge may im*643pose the minimum, the maximum, or any other sentence within the range.:.. ”). Therefore, under Harris, due process concerns do not require that a higher standard of proof be satisfied.
The question arises whether Dare should be resenteneed following Booker because he was sentenced in 2004 under a then-mandatory guidelines sentencing system. We decline to vacate the sentence and remand for resentencing pursuant to Booker because the outcome of Dare’s re-sentencing could not possibly be different. See Jones, 418 F.3d at 732; Duncan, 413 F.3d at 684 (“If Mr. Duncan were to be resentenced, the district court would still have no discretion to sentence him on the firearm offense to less than the statutory thirty-year minimum.”). The district court found that the firearm was “discharged” during a drug trafficking crime. This “sentencing factor,” under § 924(c) and Harris, requires the district court to sentence the defendant to a mandatory minimum sentence of ten years. 18 U.S.C. § 924(c)(l)(A)(iii). There was no other sentencing guidelines range binding the district court that resulted in statutory Booker error. We have no reason to question the district court’s factfinding,4 and it is not our role to question the mandatory minimum sentences under § 924(c) or the federal prosecution of this individual case.
AFFIRMED.
. Dare had no prior criminal convictions.
. Cf. United States v. Harris, 397 F.3d 404, 411-12 (6th Cir.2005) ("If we look only at the theoretical possibility of a life sentence for any § 924(c) violation, the reasoning of Booker suggests that there is no Sixth Amendment violation.”) However, under the Guidelines regime, a life sentence was only possible-absent an upward departure — for a person who, having previously been convicted for a violation of § 924(c), is again convicted of violating the subsection, the second time with a very serious weapon. See 18 U.S.C. § 924(c)(l)(C)(ii) (mandating life sentence only in the case of a 'second or subsequent conviction under this subsection’ where 'the firearm involved is a machinegun or destruc-live device, or is equipped with a firearm silencer or firearm muffler’). Given the severe constraints on imposition of a life sentence in the pre-Booker world, it would seem strikingly at odds with the principles set forth in Booker to hold that the sudden advisory nature of the Guidelines prevents the (still mandatory) provisions of § 924(c) from violating the "Sixth Amendment.”)
. Dare additionally argues that the district court erroneously rejected his argument on the effect of his intoxication. Dare asserts that "brandishing” under the definition in 18 U.S.C. § 924(c)(4) requires a showing of specific intent that the display of the firearm was *642to "make the presence of the firearm known to another person in order to intimidate that person.” The district court determined that Dare "discharged” the firearm in relation to the drug offense and sentenced accordingly. "Discharge” is not.defined in § 924(c). We conclude that a "discharge” requires only a general intent. Voluntary intoxication is not a defense to a general intent offense. See United States v. Jim, 865 F.2d 211, 212-14 (9th Cir.1989). The district court did not err in rejecting Dare's intoxication argument.
. Cf. United States v. Groce, 398 F.3d 679, 682 n. 2 (4th Cir.2005) ("The factual conclusion that the gun was brandished did result in the imposition of a sentence which is higher than the five-year maximum sentence which was available under the guidelines for the use, carry, or possession of a gun absent a brandish. However, to the extent this increase in Groce’s sentence is problematic under United States v. Booker,-U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), any problem will be remedied when the district court resentences under the advisory guidelines.”).
