Limitations on Cross-Examination
Federal Rule of Evidence 403 provides:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
The decision to exclude otherwise relevant evidence under Fed.R.Evid. 403 is ordinarily within the sound discretion of the trial court. United States v. Ramirez, 871 F.2d 582, 584 (6th Cir.), cert. denied, — U.S. -, 110 S.Ct. 127, 107 L.Ed.2d 88 (1989). This decision, based on the exercise of judgment in the context of the entire trial, ordinarily should not be overruled on appeal except for an abuse of discretion. Id.; United States v. Stull, 743 F.2d 439, 445 (6th Cir.1984), cert. denied, 470 U.S. 1062, 105 S.Ct. 1779, 84 L.Ed.2d 838 (1985).
a.
Cross-Examination of Sellers Regarding Prior Drug Use
Poindexter contends that the district court erred by prohibiting cross-examination concerning inconsistencies between Sellers’ trial testimony regarding prior drug use and her testimony at a prior hearing. The court refused to allow this cross-examination because it was confusing and misleading, and the statements were not inconsistent. Although the cross-examination was conducted by counsel for codefendant Day, Poindexter’s counsel joined in the objection to the ruling and thus Poindexter has standing to challenge this ruling on appeal.
On cross-examination, Sellers told counsel for Day that she had previously used drugs. Day’s counsel then asked whether she recalled Poindexter’s counsel asking her if she had used drugs. She responded:
A. No, I remember him accusing me. You can recall his statement.
Q. Do you recall [Poindexter s counsel] asking you while you were under oath: “QUESTION: Do you have trouble recalling because you used drugs yourself?”
And answering: “No, I don’t.”
“QUESTION: You don’t recall using drugs at all?
Once again addressing the witness, Day’s counsel then asked, “So, if those questions and answers I just read you were accurate, you didn’t tell the truth, did you?” The prosecutor objected that “[w]hat he has asked her there is not what he’s asking about here, her ability to recall.” The court agreed. Then, with the jury excused, the court reviewed the prior testimony to which counsel had referred. At the prior hearing, Sellers testified that she could not “recall days or what was going on those days.” Counsel then asked if there was any reason she had trouble recalling. The questions from the prior hearing quoted at trial, when read in context, ask Sellers whether her trouble recalling dates was related to drug use, not whether she recalled using drugs. We do not believe that the district court abused its discretion in finding that Sellers’ prior testimony, that drug use did not affect her memory, was not inconsistent with her statement at trial that she had used drugs, or in holding that the discussion of drug use in the two statements would confuse the jury.
b.
Cross-Examination of Sellers Regarding Amount of Cocaine Purchased
Sellers testified on cross-examination that she purchased an “eight ball” of cocaine from Poindexter. She further testified that she did not know how much cocaine was in an eight ball but that the cocaine she purchased cost her $250. She testified that she gave the full amount of her purchase to the police. Later in the trial, defense counsel asked Officer Balee if an eight ball contained an eighth of an ounce of cocaine. The officer testified that he believed so. The prosecution objected
