Appellant, Christopher Bourn, appeals from his conviction by a jury of possession with intent to distribute phencyclidine (PCP) and cannabis (marijuana), and possession of marijuana, D.C.Code § 33-541(a)(l) & (d) (1985 Supp.). Among his claims of error are (1) the use of his testimony at a suppression hearing to impeach him at trial; (2) the failure to strike the testimony of witnesses who allegedly violated the rule on witnesses; (3) the lack of adequate instructions of unanimity; and (4) the imposition of a separate sentence for possession of marijuana which is a lesser included offense of possession with intent to distribute marijuana. We hold that the trial court did not err in allowing appellant to be impeached at trial with his testimony on cross-examination at the suppression hearing. We find no abuse of discretion by the trial court in declining to strike witnesses’ testimony and no plain instructional error regarding unanimity. However, we agree that appellant’s conviction for possession of marijuana must be vacated. Accordingly, we affirm the judgment except to remand to the trial court with instructions to vacate the conviction for possession of marijuana.
I
On December 27, 1985, at approximately 4:00 p.m., while on non-uniformed patrol in an unmarked police cruiser in the 1300 block of C Street, S.E., an area known for PCP and marijuana trafficking, four police officers spotted a man, later identified as appellant, standing in an open breezeway next to an unidentified woman. Appellant was holding a plastic bag containing a number of small tinfoil envelopes similar to those customarily used to package PCP for sale, and passing something to the woman. Suspecting that a drug transaction was taking place, the officers got out of the car. As they approached, appellant ran out of the breezeway, shoving one officer aside as he ran. Another officer tackled him, and, with assistance, subdued appellant who attempted to swallow the plastic bag as he lay struggling in the street.
The plastic bag contained ten tinfoils, and three manila envelopes were found in appellant’s jacket pocket. A search of the breezeway produced three additional tin-foils. The manila envelopes were later determined to contain marijuana and the contents of the tinfoils tested positive for PCP-laced marijuana.
An expert testified that the events were consistent with the distribution of drugs.

Appellant contends that the trial judge committed reversible error in permitting the prosecutor over defense objection to impeach him at trial with his suppression hearing testimony. He maintains that his cross-examination testimony at the suppression hearing was improper because it exceeded the scope of his direct examination, and that the error was compounded when it was used in a highly prejudicial way to impeach him at trial. We disagree.
First, appellant’s cross-examination at the suppression hearing about whether he had seen or sold PCP or marijuana did not exceed the scope of the direct testimony.
See United States v. Williams,
Second, to decide whether the use of appellant’s suppression hearing testimony to impeach him at trial was highly prejudicial because appellant alleges it urged guilt by association, we first must decide the question reserved by the Supreme Court in
United States v. Salvucci,
Clearly, the possibility that a defendant's prior testimony may be admitted at trial, for whatever purpose, is likely to have some deterrent effect on a defendant who contemplates asserting a Fourth Amendment right. However, the Supreme Court has repeatedly held that an impermissible burdening of rights is not shown by a mere finding that a choice imposed upon the defendant may have a “discouraging effect on the defendant’s assertion of his trial rights.”
Chaffin v. Stynchcombe,
Under the trial judge’s ruling, appellant could assert his Fourth Amendment right only by assuming the risk that his testimony would later be used to impeach him at trial. Consequently, his burden is that which a defendant choosing to raise a Fourth Amendment claim bears in being obliged to testify consistently or face the consequences of impeachment at trial. The question becomes whether, by admitting prior testimony from a suppression hearing as impeachment evidence at trial, the resulting benefits to society, measured in terms of testing the trustworthiness of defendant’s trial testimony, outweigh the discouraging effects on a defendant’s assertion of his Fourth Amendment rights and his right to testify at trial.
The Supreme Court has determined in various contexts that the right to testify at trial cannot be construed to include the right to commit perjury.
See Nix v. White-side,
The United States Court of Appeals for the District of Columbia Circuit has also viewed suppression hearing testimony as proper impeachment material of the defendant at trial.
Woody v. United States,
Appellant faced no “intolerable”
Simmons
dilemma here. At trial he admitted knowing what PCP and marihuana looked like. On cross-examination, the prosecutor impeached him with his prior suppression hearing testimony denying knowledge of what they looked like. Having taken the witness stand, appellant was obliged to testify truthfully or face the consequences, and he cannot complain when his suppression testimony was used, not as direct evidence of guilt, but to impeach his trial testimony.
See Harris, supra,
Ill
Appellant further contends that the trial judge abused her discretion in failing to strike testimony of the police officers who allegedly violated the trial court’s rule on witnesses.

The trial court has broad discretion in determining the appropriate remedy for alleged violations and we find no abuse of discretion.
Nowlin v. United States,
The rule on witnesses generally prohibits witnesses from discussing their actual or prospective testimony, 6 Wig-more,
Evidence
§ 1838 (Chadbourn rev. 1976), and thereby
“
‘tailoring (it) to that of earlier witnesses’.”
Brown v. United States,
During a break in the testimony of Officer Wallace at the suppression hearing, between his direct and cross-examination, the trial judge, in response to defense counsel’s request, warned the officer to comply with the rule on witnesses. Nevertheless Wallace informed other officers that the police property book entry did not show that any money was seized from appellant. Although appellant has not demonstrated that a rule on witnesses was imposed at trial, and the transcript of the suppression hearing suggests that the rule was requested and granted only for the time between Officer Wallace’s direct and cross-examination at the suppression hearing, assuming a rule on witnesses at trial, there is no evidence that Wallace attempted to alter either his own testimony or that of the other officers. Defense counsel had ample opportunity to cross-examine each witness on the nature and scope of the rule violation, and the minor factual inconsistencies in the officers’ testimony suggests the absence of any collusion.
Cf. United States v. Arruda,
Further, had the officers conformed their testimony, the prejudicial effect would
*1318
seem minor since evidence of large sums of money rather than no money is probative of guilt on a charge of possession with intent to distribute a controlled substance.
8
Consequently, assuming the government gained a benefit from the conformed testimony, it was negated by the broad cross-examination of the witnesses.
Brown, supra,
IV
Appellant also contends that plain error occurred because the trial judge failed to instruct the jury that there must be unanimity as to a finding of marijuana in the tinfoil packets recovered from petitioner’s or unanimity as to a finding of marijuana in the tinfoil packets recovered from the breezeway or unanimity as to both, relying on
Hack v. United States,
V
The government concedes on appeal, and we agree, that appellant’s conviction for possession of marijuana merged as a lesser included offense in his conviction for possession with intent to distribute marijuana.
See Brown v. United States,
Affirmed in part and remanded with instructions.
Notes
. Defense counsel objected to the relevance of this question. The trial judge ruled that the defense had opened the door, and we find no error by the trial judge in light of appellant’s admitted association with the area and his broad denials on direct examination.
See Morris v. United States,
. Appellant relies principally on
Havens
to claim that his impeachment with the suppression testimony was improper. In
Havens
the defendant did not make a statement during his direct testimony that reasonably could have been impeached by the suppressed evidence. Only when forced to testify about that evidence on cross-examination did he offer an impeachable statement.
Havens, supra,
. Appellant erroneously characterizes the issue on appeal as a situation in which the prosecutor "set up” the defendant on cross-examination to be impeached, analogizing what occurred to
Wright v. United States,
. While recognizing that a major purpose of the exclusionary rule for illegally seized evidence is to deter the police from exercising unconstitutional practices, the Court has determined that the additional deterrence to be gained from
*1316
excluding this evidence on the issue of defendant’s credibility was outweighed by the need for truth-seeking evidence at trial.
Harris, supra,
. Although juries who hear impeachment evidence may sometimes be disinclined or unable to disregard the evidence's probative value as to guilt, and evidence inadmissible under
Simmons
may thereby be improperly considered by the jury,
see, e.g., Bruton v. United States,
. Appellant's trial testimony was filled with contradiction, inconsistency and evasion. For example, his recollection of the events of his arrest was unclear. Further, his testimony was indirectly impeached by the testimony of four police officers.
. Appellant is mistaken that the trial judge abused her discretion by failing to respond to a motion for mistrial on these same grounds. The judge specifically denied appellant's motion for a mistrial.
. Appellant testified he had $219 at the time of his arrest and that it was seized by the police.
. Appellant contends plain error occurred when the voir dire of the officers occurred in the jury’s presence, relying on
Smith v. United States,
.Appellant’s reliance on
Hack, supra,
is misplaced. In
Hack,
the defendant was linked to "two separate samples of marijuana: that in the yellow bag which was treated with PCP and that found in the transport car in which (defendant) rode after being arrested."
Likewise, in
Brown v. United States,
. Appellant's other claims are meritless. His argument that the government failed to establish a complete chain of custody for the drugs is based, the government maintains, on an error in the original trial transcript. In the absence of a certification under D.C.App.R. 10(d), we consider the uncorrected transcript, and upon doing so, conclude that the government met its burden of proof. Officer Mitchell testified that he put all the evidence in a lockseal envelope and the thirteen packets were found therein. Since there was no gap in the chain of custody, appellant’s claim of prejudice from Officer Kearney’s testimony that the tinfoils recovered from the breezeway resembled packets typically used to package PCP also fails, and the trial judge did not err in denying appellant's motion for acquittal on the ground that there was insufficient evidence that the tinfoils contained controlled substances.
Nor do we find any error, much less plain error, by the trial judge as a result of her comment regarding a possible stipulation between the parties. The record does not support appellant's claim that the trial judge refused to allow the stipulation to be made. Rather the judge opined that the proposed stipulation might be improper because damaging to defense and defense counsel responded, “Very well, Your Honor. We will not stipulate to anything.”
