A distriсt court jury in the Western District of Louisiana convicted appellants Bennie Ray Winship and Jerry Bice on four counts of federal controlled substances violations. Counts I and II involve conspiracy, charging respectively conspiracy to possess with intent to distribute marijuana and conspiracy to possess with intent to distribute methamphetamine. Count V charges defendants with aiding and assisting one another in possessing marijuana with intent to distribute; Count V parallels Count IV, but involves methamphetamine. 1
*1120 At trial the government sketched a network of drug distribution taking in areas of Texas, Oklahoma and Louisiana, with final “distribution to consumers” occurring in Alexandria, Louisiana. The sources of the marijuana lay in South Texas and in Oklahoma, while the methamphetamine came from Oklahoma. The government’s case against the appellants emerged primarily from the testimony of six indicted co-conspirators, five of whom claimed that they had personally participated in the distribution of illegal drugs in Alexandria, Louisiana. 2 Testimony from Anthony Brown, Joseph DeSoto, Jack Godeau, and John Hod-nett implicated appellants as the Oklahoma source of the marijuana and methamphetamine. According to that testimony, Win-ship and Bice sоld substantial quantities of both drugs out of Winship’s home in Eagle-town, Oklahoma. Although neither appellant ever traveled to any location within the Western District of Louisiana, trial testimony reflected their awareness of their cocon-spirator’s distribution activities in Louisiana.
Upon appellants’ conviction by the jury of all four counts, the trial judge sentenced Winship to two consecutive five year terms, a five year term to run concurrently with the others, and five years probation to begin after expiration of the jail terms. Bice received three five year sentences, all to run concurrently, and five years probation.
I. ISSUES ON APPEAL
Winship and Bice raise numerous points on appeal, the majority of which clearly lack merit. As to these patently meritless claims, we find no reason to belabor the obvious and therefore deny them without discussion. Appellants raise four issues on appeal, however, that do justify a more explicative approach. First, they claim that the trial court’s admission of hearsay evidence, in the absence of substantial independent evidence of a conspiracy in which appellants were members, violated the standard established in
United States v. James,
II. THE JAMES ISSUE
The reсord here reveals that early in the government’s case the trial judge admitted substantial coconspirator testimony that would have constituted inadmissible hearsay unless it had met the requirements of Fed.R.Evid. 801(d)(2)(E). This definitional section of the Rules removes a statement from the realm of hearsay if the statement is “offered against a party ... and is a statement by a coconspirator of a party during the course of and in furtherance of the conspiracy." Id. We review the trial *1121 court’s admission of the “potential hearsay’ under the oft-quoted standard of United States v. James, supra:
The district court should, whenever reasonably practicable, require the shоwing of a conspiracy and of the connection of the defendant with it before admitting declarations of a coconspirator. If it determines it is not reasonably practical to require the showing to be made before admitting the evidence, the court may admit the statement subject to being connected up.
Regardless of whether the proof has been made in the preferred order, or the coconspirator’s statement has been admitted subject to later connection, on appropriate motion at the conclusion of all the evidence the court must determine as a factual matter whether the prosecution has shown by a preponderance of the evidence independent of the statement itself (1) that a conspiracy existed, (2) that the coconspirator and the defendant against whom the eoconspirator’s statement is offered were members of the conspiracy, and (3) that the statement was made during the course and in furtherance of the conspiracy. Rule 801(d)(2)(E). If the court concludes that the prosecution has not borne its burden of proof on these issues, the statement cannot remain in the evidence to be submitted to the jury.
During testimony by the government’s first witness, the district judge below acknowledged that the testimony raised a James issue. Although stating a “preference” that the government follow the James order of presenting evidence, the judge specifically declined to limit initial government testimony to independent evidence of the conspiracy. He stated his intention to determine whether James had been complied with after the government rested its case. Record Vol. Ill, p. 83. However, no specific, articulated ruling on James was even made; rather, at the close of the government’s evidence the district court simply overruled appellants’ mоtions to dismiss and strike.
Appellants advance three arguments with respect to the
James
issue. First, they contend that the trial court erred in not following
James’ preferred
order of admitting evidence. Neither
James
nor subsequent cases interpreting it support appellants’ argument. The trial court has “discretion to determine the application of the
James
ruling and rationale in the specifics of the trial setting encountered.”
United States v. Whitley,
Appellants also argue that the district court never made the “later connection” determination. They point to the absence of articulated findings to that effect. However, the fact that the trial judge failed to specifically articulate his
James
findings does not necessarily mean that he never decided the “later connection” issue. On the contrary, circumstances in this case indiсate that the
James
issue received careful consideration. The record makes it clear that the trial judge was fully aware of the
James
issue during the trial. Moreover, he specifically stated that he intended to rule on the matter at the close of the government’s case. We find that in the circumstances here, just as in
United States v. Whitley, supra,
Finally, appellants argue the merits of the “later connection” issue, asserting that the government failed to present adequate independent evidence of the conspiracy and the appellants’ role in it. We review these claims under the “clearly erroneous” standard.
United States v. Ackal,
III. AN UNCHARGED SOUTH TEXAS CONSPIRACY?
Appellants contend that the trial judge admitted еvidence regarding two separate and distinct marijuana conspiracies— one occurring in Louisiana and Oklahoma and one occurring in South Texas and Oklahoma. They further contend that this variance between the indictment and the proof resulted in prejudice, claiming that introduction of evidence on a geographically and conceptually distinct “South Texas conspiracy” surprised them at trial. A reversal in this case, based on variance between indictment and proof, would require two findings: (1) the evidence at the trial actually proved two separate conspiracies and (2) the variance affected “the substantial rights” of the appellants.
See Berger v. United States,
Initially, we note the factors that enter into whether a given criminal venture constitutes more than one conspiracy. The crucial factor in finding a single conspiracy centers on whether the alleged coconspira-tors all took part in a common plan or scheme.
United States v. Elam,
Unless the evidence presented at trial establishes separate conspiracies as a matter of law,
4
whether a single conspiracy or multiрle conspiracies existed is a question for the jury to determine.
United States v. Elam,
In submitting the “single versus multiple conspiracies” question to the jury, the trial judge instructed them to disregard all evidence concerning South Texas unless they found that the Texas suppliers belonged to the same conspiracy as appellants. Record, Vol. IV, pp. 254-56. The court emphasized two factors for the jury to consider in deciding whether the government proved one or two conspiracies.
In order to find that either defendant was a member of the same conspiracy with South Texas suppliers and responsible for 'he acts and declarations of the South Texas suppliers, you must find, first that the Texas suppliers were furthering a common purpose or objective of the conspiracy served by the defendants, and, two, that the defendants had general knowledge of the existence оf other suppliers.
Record, Vol. IV, pp. 255-56. Without endorsing these jury instructions as a paragon of perfection, we find that they sufficiently framed the issue for the jury.
However, the jury’s conviction of the appellants, in itself, tells us nothing about wiiut testimony they considered— whether they found one or two conspiracies. Fortunately, as
Berger v. United States, supra,
In
Kotteakos v. United States, supra,
IV. VENUE
Appellants raise more than a “pedantic, justice-defeating technicality”
5
in asserting venue related rights. As this
*1124
Court has previously noted,
see, e.g., United States v. White,
Although venue is a constitutional right and an element of every crime, and despite the Supreme Court’s command that it not be treated as a formality, courts have dealt with venue questions differently from other constitutional rights and other elements of crimes. For instance, the standard for finding a waiver of venue rights is much more relaxed than the rigorous standard for finding waivers of the right to trial by jury, the right to confront one’s accusers or the privilege against compulsory self incrimination.
See Boykin v. Alabama,
In addition, the burden of proof in establishing venue differs from the burden of proving other elements. The prosecution need only show the propriety of venue by a preponderance of the evidence, not beyond a reasonable doubt.
United States v. Turner, supra,
Barriers do exist, however, to prevent the government from trammelling a defendant’s venue rights. The rule in this
*1125
circuit is that failure to instruct on venue is reversible error when trial testimony puts venue in issue and the defendant requests the instruction.
Green v. United States, supra,
First, we must determine whether appellants requested a venue instruction. Appellants’ trial took place in the Western District of Louisiana. All four counts of which they were convicted designated the Western District as the situs of the offenses. 10 Appellants did not submit a written jury instruction on venue nor did they request such an instruction at the jury charge conference. It was not until after the jury was instructed that appellants’ counsel requested an additional instruction that the jury must find “some element of each of these counts charged, happened in the Western District of Louisiana.” Record Yol. IV, pр. 266-267. The trial judge refused the venue instruction request. Despite appellants’ eleventh hour timing, we find that they properly requested a venue instruction.
Next, we reach the question of whether trial testimony put venue in issue. The law concerning propriety of venue, therefore, becomes relevant. Venue is proper in conspiracy offenses in any district where the agreement was formed or an overt act occurred.
United States v. Pozos,
Understanding the law on propriety of venue, we now consider the testimony presented at appellants’ trial. Evidence that drug related activities, including possession and distribution, occurred within the Western District was overwhelming. Such evidence surfaced throughout the testimony of four of the government’s main witnesses; each of the four located major portions of their drug related activities within the Western District of Louisiana. 12 Record, Vol. Ill, pp. 23, 67, 90; Vol. IV, p. 113; Vol. V, p. 4. This testimony and the lack of any contradictory evidence compels the conclusion that trial testimony did not put venue *1126 “in issue.” The concept of “in issue” simply will not stretch so far. Consequently, despite the request for a venue instruction, appellants fall outside the protection of Green v. United States, supra, and United States v. White, supra. We can find no reversible error in the failure to give a venue instruction. 13
V. DOUBLE JEOPARDY
Appellants’ two conspiracy convictions both came under 21 U.S.C. § 846. Count I named 16 conspirators, pertained to the period from December 1, 1979, until May 20, 1982, and involved marijuana. Count II named 9 conspirators, pertained to the period from January 1,1979, until May 20,1982, and involved methamphetamine. Claiming that Counts I and II are “in law and fact” the same offense, appellants urge that they have been twice placed in jeopardy for the same crime.
See United States v. Marable,
The constitutional guarantee against double jeopardy prohibits multiple prosecutions for the same offense. In conspiracy cases, this court has formulated special rules to enforce that guarantee.
See id.
Those rules derive from the notion that the essence of a conspiracy offense lies in the
agreement
to violate the law.
See id.; United States v. Tammaro,
For each conspiracy conviction the government seeks, it must prove a corresponding, separate agreement. But frequently, proof of the unlawful agreement or common purpose in conspiracies does not flow from direct evidence. In many cases, the jury reaches its verdict based on inferences from circumstantial evidence. Thus, that same circumstantial evidence must provide the basis for a double jeopardy analysis in conspiracy cases.
United States v. Marabie, supra,
suggests five focal points for determining whether evidence in a conspiracy trial proves more than one offensе: (1) the time-frames of the charged conspiracies; (2) the persons acting as conspirators; (3) the statutory offenses charged in the indictment; (4) the overt acts charged by the government or any other description of the offense charged which indicates the nature and scope of the activity which the government sought to punish in each case; and (5) the places where the events alleged as part of the conspiracy took place.
These factors, when applied in the instant case, point consistently toward a single conspiracy. With regard to the first factor, a substantiаl time correspondence exists between the active periods of the purportedly separate conspiracies. The marijuana conspiracy occurred wholly within the period of the methamphetamine conspiracy. Furthermore, the evidence adduced at trial indicated no event to mark a specific beginning of either conspiracy. In arguing that a significant time difference existed between the two counts, the government points only to one conspirator’s testimony that he did not deal marijuana with defendants during 1980. This testimony alone, however, hardly establishes a significant time differential between the working periods of the drug operations. Overall, the time element cuts in favor of the existence of one conspiracy.
*1127 An examination of the second factor reveals that a core cast of characters was the same in both conspiracies. Eight individuals were charged with both crimes. Only one individual 14 was named in the methamphetamine count and not named in the marijuana count. As to that one individual, trial testimony never suggested that he played a significant role in the conspiracy. Although five individuals were named in the marijuana count who weren’t named in the methamphetamine charge, one of these five, Tommy Hodnett, testified that he also took part in a methamphetamine deal. Record, Vol. IV, p. 224. Overall, the proof adduced at trial drew no distinct line between the perpetrators of the alleged “marijuana conspiracy” and those involved in the alleged “methamphetamine conspiracy.” And, as the Hodnett testimony reveals, we cannot rest a conclusion of separate conspiracy personnel on the government’s decision of who to charge in specific indictments. Accordingly, the cast of characters element here indicates a single conspiracy.
Marable’s third factor, the statutory offenses charged in the indictment, is also consistent with a single conspiracy charge. As noted above, both indictments charged violations of Section 846.
Factor four is not telling either way. Because no overt act need be alleged in a Section 846 indictment, the charge contains no description of the offense other than the time, location, and drug involved.
In terms of the location element, though, significant parallels exist between the two charged conspiracies. The main distribution line for marijuana and methamphetamine ran from Oklahoma to Louisiana. Although the government presented evidence of South Texas marijuana sources, the great majority of evidence establishing conspiracy concerned Oklahoma and Louisiana locations. Thus, the location element indicates a single conspiracy.
The double jeopardy prohibition would not allow separate public drunkenness convictions for a man who drank enough of two whiskies to be drunk on either liquor. Public drunkenness laws do not inquire whether the violators consumed Old Crow or Chivas Regal. Similarly, whether the government may bring separate Section 846 chаrges does not hinge on whether separate controlled substances were involved. In this case, analysis of the Marable factors provides objective indications of a single agreement. Furthermore, the conspiracy was clearly not departmentalized or compartmentalized in the minds of the conspirators. One conspirator’s testimony emphasized the close links between efforts to sell the two drugs. Jack Goudeau could not recall whether he was buying marijuana or methamphetamine when he first met appellant Winship. Record, Vol. V, p. 6. We see no logic or reason to dichotomizе the conspiracy here. This criminal blend came from a single agreement to sell two drugs. We cannot allow the government to distill separate offenses from that agreement by prosecuting for each kind of drug. Counts I and II constituted a single offense. Appellants’ right not to be twice placed in jeopardy for the same offense was violated.
VI. CONCLUSION
In summary, we find no basis for reversal in appellants’
James
argument, variance argument, or venue instruction claim. Additionally, we have reviewed other arguments by appellants and found that they too lack merit. We do find error, however, in appellants’ being convicted on two separate conspiraсy counts. Therefore, we reverse the Count I conviction and affirm the Counts II, IV and V convictions.

.In finding failure to instruct on venue not to be plain error, the White court reliеd on (1) the fact that the trial judge sent a written copy of the indictment, reciting the location of the crime, into the jury room; (2) the trial judge’s instruction that the government must prove the crime “as charged;” (3) the defense counsel’s action in arguing venue in closing argument; and (4) the court’s finding that there was sufficient evidence for a jury to find venue proper.

. This holding does not mean that we approve of the trial court’s failure to give the requested instruction. We do not hold the fаilure to instruct upon request to be error only because we do not reach the issue; overwhelming evidence of proper venue in this case makes any such error harmless.
Previous dilutions of venue rights do not deny venue’s constitutional basis or its status as an essential element of every federal crime. Whether trial testimony puts venue in issue will not always be as clear cut as in this case. When a venue instruction is requested, the burden of giving an instruction weighs lightly against the value of safeguarding venue rights. The better procedure is to give the venue instruction when requested, regardless of whether the trial court believes trial testimony has put venue in issue.'
