A jury in the United States District Court for the Southern District of Texas convicted Salvador Garcia, Jr., Jorge Rolando Garcia, Sr., and Toribio ArriagaGuerrero of multiple charges related to a drug-trafficking operation. The defendants appeal their convictions by challenging various district court rulings. We find no merit in the defendants’ appeals and affirm the convictions on all counts.
I. BACKGROUND
A Facts
“We recite the facts in the light most favorable to the verdict.”
United States v. Olis,
On the morning of November 30, 2003, Salvador Garcia, Juan Garcia, ArriagaGuerrero, and other participants planned to acquire and transport a large quantity of marijuana. Arriaga-Guerrero, who had left the operation some time during the preceding few weeks, informed Juan Garcia of his desire to return and asked for a role in that day’s operation. Although Salvador Garcia opposed Arriaga-Guerrero’s continued participation, Juan Garcia allowed it, and instructed Arriaga-Guerrero *725 to serve as the operation’s lookout at a nearby gas station. Arriaga-Guerrero agreed. Juan Garcia and two other participants drove a GMC Yukon to the river landing near the Midway property, loaded several hundred pounds of marijuana into the vehicle, and headed back to the Midway property where the group sometimes stored vehicles in sheds.
Meanwhile, ground sensors alerted United States Border Patrol agents to activity near the river landing. Two agents went to the river landing, discovered evidence of recent activity, and began following tire tracks towards the Midway property. Juan Garcia received warning of the approaching government agents, and left the other two members of the operation at the Midway property to tend to the load of marijuana. As immigration agents neared the Midway property compound and observed persons fleeing the vehicles, one of the agents saw two bundles of what the agent believed to be marijuana fall out of the Yukon. The agents’ search of the Yukon, the other vehicles on the property, and the buildings there yielded 759 kilograms of marijuana, several firearms, and accompanying ammunition.
On December 2, 2003, officers conducting an unrelated investigation came upon Jorge Garcia’s Agua Verde property, which emanated a strong odor of marijuana. After obtaining a warrant, the officers searched the home and seized 3,470 kilograms of marijuana, as well as another firearm and ammunition. One person testified that he saw Jorge Garcia flee the Agua Verde property near the time of the seizure.
B. District Court Proceedings
In this case’s first trial, the government charged Salvador Garcia and ArriagaGuerrero with the following:
(1) Conspiracy to possess more than 1,000 kilograms of marijuana with intent to distribute from October through December 2, 2003, see 21 U.S.C. §§ 846, 841(a)(1), and
(2) Possession of approximately 759 kilograms of marijuana with intent to distribute on November 30, 2003, see § 841(a)(1).
The government also charged Salvador Garcia with the following:
(3) Maintaining drug-involved premises, see 21 U.S.C. § 856,
(4) Possession of firearms in furtherance of a crime, see 18 U.S.C. § 924(c)(1)(A), and
(5) -(26) Twenty-two counts of violating financial reporting requirements, see 31 U.S.C. § 5324(a).
Salvador Garcia and Arriaga-Guerrero presented motions for acquittal on all counts at the end of the government’s case-in-chief, and again before the district court charged the jury; the district court denied the motions. The jury failed to return a verdict on Counts One through Four, and the district court declared a mistrial as to those counts. 1
For the second trial, the government’s superceding indictment charged Salvador Garcia, Arriaga-Guerrero, and Jorge Garcia with identical versions of the first trial’s Count One conspiracy and Count Two possession charge. The indictment also charged Salvador Garcia with identical versions of the Count Three drug-involved premises and Count Four firearm charges. New Count Five charged Salvador Garcia and Jorge Garcia with possession of more than 1000 kilograms of marijuana with intent to distribute on December 2, 2003. See 21 U.S.C. §§ 846, 841(a)(1). The jury found Salvador Garcia guilty of all but the *726 firearms charge, and the district court sentenced him to a 365-month term of imprisonment. The jury found Arriaga-Guerrero guilty of the conspiracy and possession charges, and the district court sentenced him to a 240-month term of imprisonment. The jury found Jorge Garcia guilty of the conspiracy and possession charges, and the district court sentenced him to a 235-month term of imprisonment.
All three defendants appealed. We have jurisdiction over these appeals from final judgments.
See
28 U.S.C. § 1291. We consolidated the appeals for purposes of argument and we now consolidate them for disposition.

II. DISCUSSION
A. Salvador Garcia
1. Rule jOí(b)
In his first issue, Salvador Garcia challenges his convictions on all counts by arguing that the district court violated Federal Rule of Evidence 404(b) when it admitted evidence of cocaine trafficking and cocaine use. During the course of the four-day trial on the marijuana charges, the district court admitted evidence showing that Salvador Garcia’s operation moved cocaine through the Midway property using the same vehicles and the same passageway, that the conspirators packaged the cocaine in bags of horse feed, and that Salvador Garcia took cocaine to McAllen, Texas. The district court also admitted evidence showing that Salvador Garcia gave members of the operation cocaine as payment for their work, and that the members consumed cocaine for the purpose of staying awake during the marijuana and cocaine trafficking operations. According to Salvador Garcia, the district court should have excluded the evidence under Rule 404(b) because the government failed to give Salvador Garcia notice of its introduction, and because the evidence’s probative value did not outweigh its unfair prejudice.
Because Salvador Garcia failed to object when the government introduced the evidence,
2
we review the district court’s decisions for plain error only.
See United States v. Akpan,
An appellate court may not correct an error the defendant failed to raise in the district court unless there is “(1) error, (2) that is plain, and (3) that affects substantial rights.” “If all three conditions are met an appellate court may then exercise its discretion to notice a forfeited error but only if (4) the error seriously affects the fairness, integrity, or public reputation of judicial proceedings.”
Mares,
Rule 404(b) limits the admissibility of extrinsic evidence, but not intrinsic evidence.
E.g., United States v. Sumlin,
We need not decide whether the cocaine evidence triggered Rule 404(b) because we can identify no plain error in the district court’s implied
Beechum
analysis.
See United States v. Nguyen,
To be sure, the introduction of cocaine evidence into a marijuana trial carries inherent prejudice, but the question Rule 403 poses is whether the cocaine evidence’s
unfair
prejudice
substantially
outweighs its relevance. Here, the cocaine evidence introduced at trial was relevant to issues of intent and knowledge, among others.
See Nguyen,
As an extension of his Rule 404(b) argument, Salvador Garcia argues that despite his failure to object or tender any alternative, the district court erred when it failed to
sua sponte
provide a specific instruction concerning the limits of the Rule 404(b) cocaine evidence. Because Salvador Garcia failed to object at trial and request the instruction he now seeks, we review the content of the district court’s jury instruction for plain error only.
See United States v. Delgado,
Salvador Garcia’s argument fails because the district court’s instructions sufficiently mitigated the risk that prejudice resulting from the cocaine evidence would affect the verdict. In addition to instructions on the elements of the offenses, the district court’s instructions included the following admonishment under the heading “CAUTION — CONSIDER ONLY CRIMES CHARGED”: “The defendant is not on trial for any act, conduct, or offense not alleged in the indictment.” 4 In Parz *729 iale, 947 F.2d 123, the district court admitted Rule 404(b) evidence and its charge gave the essential elements of each count with an almost identical additional instruction: “[T]he defendant is not on trial for any act or conduct or offense not alleged in the indictment.” Id. at 129. As we did in Parziale, id., we conclude in this case that the district court’s instructions sufficiently guarded against the risk of unfair prejudice to the defendant. Accordingly, the district court’s decision to admit the evidence of cocaine trafficking and cocaine use was not reversible error.
2. Ineffective Assistance of Counsel
In his second issue, Salvador Garcia argues that his attorney rendered ineffective assistance of counsel by failing to object to the cocaine evidence, and by failing to mitigate the effects of the cocaine evidence. Our standards for evaluating claims of ineffective assistance of counsel under
Strickland v. Washington,
First, [a defendant] must demonstrate that his attorney’s performance fell below an objective standard of reasonableness. This court has described that standard as “requiring that counsel research relevant facts and law, or make an informed decision that certain avenues will not be fruitful.” Second, [a defendant] must also prove that he was prejudiced by his attorney’s substandard performance. “[T]o prove prejudice, [a defendant] must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.”
United States v. Herrera,
[T]he “general rule in this circuit is that a claim of ineffective assistance of counsel cannot be resolved on direct appeal when the claim has not been raised before the district court since no opportunity existed to develop the record on the merits of the allegations.” Only in those rare occasions where the record is sufficiently developed will the court undertake to consider claims of inadequate representation on direct appeal. If we cannot fairly evaluate the claim from the record, we must decline to consider the issue without prejudice to a defendant’s right to raise it in a subsequent proceeding.
United States v. Gulley,
B. Toribio Arriagar-Guerrero
1. Double Jeopardy
In his first issue, Arriaga-Guerrero challenges his convictions on both counts by arguing that the district court erred when it denied his motion for a judgment of acquittal in the second trial. Specifically, Arriaga-Guerrero argues that the first trial’s evidence was insufficient to support a verdict on either charge, and that the first trial’s insufficiencies triggered Double Jeopardy Clause protections prohibiting his reprosecution in the second trial. Because Arriaga-Guerrero did not raise this argument in the district court, we review only for plain error.
See, e.g., United States v. Odutayo,
Arriaga-Guerrero’s Double Jeopardy Clause argument fails because the government placed him in jeopardy only once. In the successive prosecution context, the authorities hold that a defendant’s double jeopardy concerns arise only after original jeopardy attaches
and
terminates.
Richardson v. United States,
Richardson
and Burks’s boundaries are no longer an open question in this Circuit.
See United States v. Achobe,
After [Justices of Boston Municipal Court v. Lydon,466 U.S. 294 ,104 S.Ct. 1805 ,80 L.Ed.2d 311 (1984)] and Richardson, it appears that there are only three possible jeopardy terminating events: (1) an acquittal, (2) a trial court determination of insufficiency leading to a directed verdict of acquittal, and (3) an unreversed determination on direct appeal that there was insufficient evidence to support the conviction. In the absence of one of these events, a later determination that there was insufficient evidence apparently will not bar a retrial.
Vanderbilt,
2. Sufficiency
In his second issue, Arriaga-Guerrero challenges his convictions on both counts by arguing that the second trial’s evidence was insufficient to support a verdict on either charge. Because Arriaga-Guerrero raised his sufficiency argument in a motion for judgment of acquittal, we review the district court’s denial of that motion by examining the evidence and all reasonable inferences drawn therefrom in the light most favorable to the verdict, and asking whether a rational trier of fact could have found guilt beyond a reasonable doubt.
See, e.g., United States v. Valdez,
Arriaga-Guerrero’s conviction on Count One — conspiracy to possess more than 1,000 kilograms of marijuana with intent to distribute — required proof that “(1) an agreement existed between the defendant and one or more persons to violate the applicable narcotics laws; (2) each defendant knew of the conspiracy and intended to join it; and (3) the defendant participated voluntarily in the conspiracy.”
United States v. Infante,
Initially, Arriaga-Guerrero argues that the jury could not have relied upon Juan Garcia’s testimony because of Juan Garcia’s regular drug use. However, it is now well established that “whether judges doubt the credibility of a witness, even an accomplice cooperating with the Government, is beside the point in reviewing a sufficiency claim such as this — with the exception of cases where a witness’ testimony is so incredible or insubstantial that, as a matter of law, we may discredit it.”
United States v. Greenwood,
Next, Arriaga-Guerrero argues that the government never established the existence of an actual agreement between Arriaga-Guerrero and the persons who
*732
conducted the November 30 marijuana trafficking operation. The evidence of this fact was not insufficient because Juan Garcia testified that Arriaga-Guerrero asked to participate in the November 30 operation, and that he and Arriaga-Guerrero agreed that Arriaga-Guerrero would serve as a lookout. In addition, a federal agent testified that Arriaga-Guerrero admitted that he carried out the agreement. While Juan Garcia did not testify to reaching an agreement as to
payment
for that day’s work, a conspiracy conviction does not require proof of such details,
see United States v. Dean,
Along similar lines, Arriaga-Guerrero argues that the government failed to prove that Arriaga-Guerrero was acting as a lookout for Salvador Guerrero’s marijuana operation, as opposed to Salvador Guerrero’s cocaine operation or an operation directed by someone else. The evidence of this fact was not insufficient for two reasons. First, the government provided direct evidence of this fact in the form of Juan Garcia’s testimony that he saw Arriaga-Guerrero serving as a lookout that day, as well as evidence of Arriaga-Guerrero’s admission of the same. Second, the jury could have inferred that Arriaga-Guerrero was looking out for Salvador Garcia’s marijuana operation from the government’s circumstantial evidence — namely, evidence that Arriaga-Guerrero volunteered to work for Salvador Garcia’s operation that morning, that Juan Garcia ordered him to serve as a lookout for Salvador Garcia’s marijuana operation by going to that location, that Arriaga-Guerrero then went to the lookout location and stayed until the completion of the operation, and that Arriaga-Guerrero associated with the members of Salvador Garcia’s operation that same evening.
See United States v. Lopez,
Arriaga-Guerrero also argues that the government failed to prove the intent element of the possession count, which required proof that Arriaga-Guerrero knew that Salvador Garcia’s group intended to distribute the marijuana and intended to aid the conspiracy in that respect.
See United States v. Longoria,
S. Jury Instructions
In his third issue, Arriaga-Guerrero challenges the district court’s jury instructions by arguing that the district court should have included a limiting instruction concerning the cocaine evidence challenged by Salvador Garcia. Specifically, ArriagaGuerrero argues that the district court should have instructed the jury as to the limited purposes for which the evidence of Salvador Garcia’s acts of cocaine packaging and trafficking could be used, and that the court should have instructed the jury not to use that evidence against ArriagaGuerrero. Arriaga-Guerrero raised this issue for the first time in his reply brief; this despite our earlier order directing counsel to “file a brief addressing whether the admission of [certain testimony regarding cocaine transportation and packaging activities] was erroneous.” We often conclude that an appellant’s failure to raise an issue in its brief on the merits results in waiver.
E.g., Stephens v. C.I.T. Group/Equip. Fin., Inc.,
In exceptional circumstances, especially in criminal cases, appellate courts, in the public interest, may, of their own motion, notice errors to which no exception has been taken, if the errors are obvious, or if they otherwise seriously affect the fairness, integrity, or public reputation of judicial proceedings.
United States v. Atkinson,
We again review the content of the district court’s jury instruction for plain error because Arriaga-Guerrero failed to object at trial and request either of the instructions he now seeks.
See United States v. Delgado,
C. Jorge Garcia
1. Sufficiency
In his first issue, Jorge Garcia challenges his convictions on both counts by arguing that the government presented insufficient evidence of his presence at the Aqua Verde property on the day of the seizure. According to Jorge Garcia, the testimony of law enforcement officials conflicted with that of the other witness, a convicted felon who testified to Jorge Garcia’s presence that day. Because Jorge Garcia raised his sufficiency argument in a motion for judgment of acquittal, we review the district court’s denial of that motion
de novo,
applying the same standard as the district court.
See supra
Part II. B.2;
United States v. Valdez,
This argument does not undermine the Count One conspiracy conviction because that conviction did not require Jorge Garcia’s presence at the Aqua Verde property on the day of the seizure.
See Valdez,
2. Rule 16
In his second issue, Jorge Garcia challenges his conviction by arguing that the government violated Federal Rule of Criminal Procedure 16(a)(1)(E) by introducing photographs of the Aqua Verde home into evidence without first disclosing those photographs to Jorge Garcia. Upon a defendant’s request, Rule 16 requires the government disclose to the defendant certain items “within the government’s possession, custody, or control.” Fed. R. Crim.P. 16(a)(1)(E). According to Jorge Garcia, the government’s failure to disclose undermined his strategy of arguing that he did not live at the Aqua Verde home. “We review alleged discovery errors for abuse of discretion and will order a new trial only where a defendant demonstrates prejudice to his substantial rights.”
United States v. Doucette,
Initially, Jorge Garcia fails to demonstrate that the district court abused its discretion when it refused to punish the
*735
government for a failure to disclose. The district court determined that the photographs in question were made available to the public, and that Jorge Garcia’s inability to acquire the photos resulted from his attorney’s confusion about how to ask the clerk’s office for access. In light of the rule that “there can be no violation of Rule 16 where ... the defendant’s lack of diligence is the sole cause of his failure to obtain evidence made available by the government,”
Doucette,
Jorge Garcia also argues that the government’s failure to disclose the photographs violated the government’s duty to disclose evidence under
Brady v. Maryland,
To make out a Brady violation, “a defendant must show that (1) evidence was suppressed; (2) the suppressed evidence was favorable to the defense; and (3) the suppressed evidence was material to either guilt or punishment.” “Evidence is material under Brady when there is a ‘reasonable probability’ that the outcome of the trial would have been different if the suppressed evidence had been disclosed to the defendant.”
United States v. Miller,
3. Sentencing
Finally, Jorge Garcia challenges his sentence by arguing that the district court added two levels to the original offense level when it actually intended to subtract two levels to account for Jorge Garcia’s role in the offenses. Jorge Garcia does not challenge the district court’s calculation of the base offense level, and does not challenge the substance of the district, court’s sentencing decisions. Instead, Jorge Garcia argues only that the district court “inadvertently added two points to the offense level after stating its intention to subtract out two levels for [Jorge Garcia’s] role.” Because Jorge Garcia objected to the omission of a role reduction in the district court, we review the district court’s application of the United States Sentencing Guidelines
de novo
and its factual findings for clear error.
See, e.g., United States v. Barrera-Saucedo,
Jorge Garcia’s argument fails because the district court made no inadvertent calculation. After calculating a base offense level of thirty-four, see United States Sentencing Guidelines Manual § 2D1.1(a)(3) (2004), the district court enhanced the base offense by two levels for possession of a dangerous weapon, see id. § 2Dl.l(b)(l). Although the presentence investigation report recommended another two level enhancement for organizing, leading, managing, or supervising the activity, see id. § 3Bl.l(c), the district court rejected that recommendation. The district court also rejected Jorge Garcia’s request for a mi *736 nor participant reduction, see id. § 3B1.2(b), and concluded that Jorge Garcia’s involvement was “pervasive and over a long period of time.” Contrary to Jorge Garcia’s suggestion, when the district court said that “[a]fter making the two-point adjustment, he’s at a Level 36 when I subtract out his role,” the court was referring to its rejection of the § 3Bl.l(c) role enhancement, not an acceptance of the § 3B1.2(b) reduction. The district court made its conclusion clear:
The Court adopts the factual findings contained within the Presentence Report. However, the Court concludes that [Jorge Garcia] should not have been assessed with an enhanced role, that he was just a regular participant. After making this modification, this would result in an offense level of 36, which is a guideline range of 188 to 235 months.
Thus, as a matter of fact, the record defeats Jorge Garcia’s contention that the district court intended to reduce the sentence to something less than level thirty-six. 6
III. CONCLUSION
For the foregoing reasons, the district court judgments are AFFIRMED in all respects.
Notes
. The first jury found Salvador Garcia guilty on Counts Five through Twenty-Six, and Salvador Garcia does not appeal that portion of the verdict.
. Salvador Garcia concedes that he failed to object to the cocaine testimony, and also that he failed to ask for a limiting instruction. His inclusion of the Rule 404(b) argument in his motion for new trial does not change the standard of review.
See United States v. Abroms,
. For almost identical reasons, Salvador Garcia’s conclusory assertion that the district court’s admission of the cocaine evidence violated the Fifth Amendment is without merit.
See Story v. Collins,
. The jury charge also included one instruction that outlined the purposes for which the jury could use Rule 404(b) evidence, but that instruction addressed only evidence of Arriaga-Guerrero’s acts.
. While our holding in
United States v. Wilkinson,
. Jorge Garcia does not challenge the substance of the district court's rejection of the § 3B 1.2 reduction argument.
