Prior to the government’s cross-examination, counsel for Lustig asked Pederson about any meetings or dealings between co-defendants. This line of inquiry was therefore opened before the government began its examination. The government was simply pursuing it. A defendant has no right to give testimony without laying himself open to cross-examination upon that testimony. Brown v. United States, 356 U.S. 148, 155, 78 S.Ct. 622, 2 L.Ed.2d 589 (1957).
Since Pederson raised the defense of entrapment, the prosecution was permitted to conduct a “searching inquiry” into the possible predisposition of the defendant. United States v. Russell, 411 U.S. 423, 93 S.Ct. 1637, 36 L.Ed.2d 1046 (1973). This inquiry necessarily includes the defendant’s knowledge of and connections with his co-defendant, since evidence of conspiratorial activity would refute a theory of entrapment. The government’s cross-examination was proper.
COCAINE
Lustig raises several familiar arguments regarding the controlled substance cocaine. He first argues that the failure to republish the schedules listing cocaine as a controlled substance is fatal to the indictment. This contention is disposed of by United States v. Eddy, 549 F.2d 108 (9 Cir. 1976) (no need for annual republication under statute).
Lustig next argues that the trial court erred by not hearing evidence about the pharmacological nature of cocaine. See United States v. Foss, 501 F.2d 572 (1 Cir. 1974). The record shows, however, that Lustig presented detailed motions to the court discussing the nature of cocaine. It would have been a waste of time for the court to hear extensive testimony on this marginal issue.
Lustig finally argues that cocaine is improperly classified as a controlled substance, since it is relatively harmless. Beyond the fact that the evidence is sharply divided about cocaine, this court has recently rejected a similar contention regarding marijuana — a substance far less dangerous and controversial than cocaine. See United States v. Rogers, 549 F.2d 107 (9 Cir. 1976).
PROSECUTION IN FEDERAL COURT
Lustig claims that prosecutors improperly “forum-shopped” for the best court in which to obtain a conviction against him. Of course, cooperation between state and federal officers often occurs, with prosecution through one court system or the other. When in federal court, federal law and procedures apply. Therefore, Alaska law is not relevant. Elkins v. United States, 364 U.S. 206, 224, 80 S.Ct. 1437, 4 L.Ed.2d 1669 (1959). A federal warrant was obtained for Lustig’s arrest, who never was indicted by the state. Moreover, numerous cases have involved similar procedural histories as this one and have been affirmed on appeal. See, e. g., United States v. Harrington, 504 F.2d 130 (7 Cir. 1974) ; United States v. Sellers, 483 F.2d 37 (5 Cir.), cert, denied, 417 U.S. 908, 94 S.Ct. 2604, 41 L.Ed.2d 212 (1973).
JURY INSTRUCTIONS
Lustig complains about several jury instructions. First he argues that the conspiracy instruction informing the jury that “very little evidence is necessary to show that a particular defendant was part” of the conspiracy was erroneous. However, it is well established that once the existence of a conspiracy is established, only slight evidence is required to connect any defendant with it. United States v. Freie, 545 F.2d 1217, 1221 (9 Cir. 1976); United States v. Westover, 511 F.2d 1154, 1157 (9 Cir. 1975) . Thus, the contested instruction correctly states the law.
Lustig also requested an alibi instruction and claims that the failure to give it was error. None of the evidence shows any “alibi” and thus the court did not have to give what would have been a misleading instruction in this case. See United States v. Dye, 508 F.2d 1226, 1231 (6 Cir. 1974); United States v. Cole, 453 F.2d 902, 906 (8
