OPINION
CAMERON, Justice.I. JURISDICTION
Defendant, David M. Soule (Soule), petitions this court to review an opinion of the court of appeals, Division I, upholding the trial court’s ruling requiring Soule to admit the elements of the crime before he could plead entrapment. 164 Ariz. 165, 791 P.2d 1048. Defendant, Herbert Donald Abrams (Abrams), petitions this court to review a memorandum decision of the court of appeals, Division II, holding that Abrams could not argue entrapment without admitting all elements of the crime. 164 Ariz. 185, 791 P.2d 1068.
Because of the similarity of the issues, we consolidated the two matters for oral argument and decision. We have jurisdiction pursuant to Ariz. Const. art. 6, § 5(3) and A.R.S. 12-120.24 and Ariz.R.Crim.P. 31.19(f), 17 A.R.S.
II. QUESTION PRESENTED
In light of the recent United States Supreme Court decision in Mathews v. United States, 485 U.S. 58, 108 S.Ct. 883, 99 L.Ed.2d 54 (1988), will we continue to follow the Arizona rule requiring a defendant to admit all elements of the crime prior to entering a plea of entrapment? 1
*135III. FACTS
A. Soule
In August 1989, a member of the Phoenix Police Department learned that Soule was selling heroin. An undercover police officer subsequently contacted Soule at his home. The officer told Soule that he was a heroin addict, but not strung out, and asked if he could buy some methadone. Soule sold him a small bottle of methadone. Five days later, the undercover police officer returned to Soule’s home and asked to buy some more methadone, which Soule sold to him. On 14 August and 22 August, the officer purchased methadone from Soule at his home and at a methadone clinic.
At trial, the officer testified on cross-examination that an informant had introduced him to Soule and that the officer had initiated contact thereafter. Soule did not testify at trial, but witnesses for Soule testified that he was trying to break his heroin and alcohol habits, was not using heroin in August, and that a person in the methadone program could receive the drug at a clinic and take it home for self-administration. The trial court, after requiring Soule to admit the elements of the crime, instructed the jury on the entrapment defense. The jury acquitted Soule on the first sale of methadone but found him guilty of three subsequent sales. Soule appealed and the court of appeals affirmed the trial court’s judgment and sentence.
B. Abrams
In May 1987, Michael Batelli, an undercover Tucson Police Officer, was investigating illegal gambling in Pima County. As part of that investigation, he went to evening card games at the home of Alex Bonivitas. Abrams was a regular player at these games. During some of the card games, Abrams went to the back room of the house with Bonivitas for several minutes. This suggested to Batelli that Abrams may have been dealing, or doing, drugs.
In October 1987, Batelli met with Abrams and told him that he was disappointed with his current suppliers and that he and Abrams should deal with each other. Abrams refused, indicating that he did not deal with anyone he had not known for ten or twenty years. Later, Abrams approached Batelli and told him that he, Abrams, was now ready to deal. They discussed prices and arranged a sale in which Abrams sold two kilos of cocaine for $35,000. Abrams’ defense was entrapment and he did not testify. After the state rested, Abrams’ counsel requested that he be permitted to argue entrapment without admitting any elements of the charged crimes. . Alternatively, counsel sought to admit only certain facts. The court denied both motions and Abrams was convicted. Abrams appealed and the court of appeals affirmed his conviction.
IV. DISCUSSION ■
We have long held that a defendant must admit all elements of an offense to avail himself of the entrapment defense. State v. Nilsen, 134 Ariz. 431, 657 P.2d 419 (1983). In Nilsen, we held that the trial court erred by giving the jury an entrapment instruction when the defendant did not testify or did not otherwise present to the jury some evidence of the defendant’s admission of the elements of the crime. Id. at 432, 657 P.2d at 420. See also State v. McKinney, 108 Ariz. 436, 501 P.2d 378 (1972) (a defendant who wishes to utilize the entrapment defense must admit substantial elements of the crime and one who denies knowledge of the crime may not raise the entrapment defense); State v. Bean, 119 Ariz. 412, 581 P.2d 257 (1978) (to claim entrapment defense, defendant must admit offense charged).
Defendants, however, urge that we follow Mathews v. United States, which permits a defendant in federal court to raise inconsistent defenses. 485 U.S. 58, 108 S.Ct. 883, 99 L.Ed.2d 54 (1988). Mathews is not based on constitutional interpretation and is binding on the federal courts only; it is not binding on the states. Under Mathews, a defendant may plead not guilty and also plead entrapment without admitting all elements of the offense. The Supreme *136Court held that “even if the defendant denies one or more elements of the crime, he is entitled to an entrapment instruction whenever there is sufficient evidence from which a reasonable jury could find entrapment.” Id. at 62, 108 S.Ct. at 886.
The majority in Mathews further said that, “[a]s a general proposition, a defendant is entitled to an instruction as to any recognized defense for which there exists evidence sufficient for a jury to reasonably find in his favor.” Id. at 63, 108 S.Ct. at 887. The majority cited as a parallel rule the submission of lesser included offenses in the instructions to the jury. Id. For example, in Stevenson v. United States, 162 U.S. 313, 16 S.Ct. 839, 40 L.Ed. 980 (1896), the Court found sufficient evidence to entitle the defendant to a manslaughter instruction and to a self-defense instruction. This holding is contrary to the entrapment inconsistency theory adopted in Nilsen. The inconsistency theory, however, is not without its detractors.
Dean Paul Marcus has noted the seeming aberration of the inconsistency theory:
The entrapment inconsistency theory is an exception to the rule in favor of inconsistent defenses. But it is an exception without any justification. There is no conceivable reason for permitting a defendant to assert inconsistent defenses in other contexts but denying him that right in the context of entrapment.
The Entrapment Defense and the Procedural Issues: Burden of Proof, Questions of Law and Fact, Inconsistent Defenses, 22 Crim.L.Bull. 197 (1986) (citing United States v. Demma, 523 F.2d 981, 985 (9th Cir.1975) (en banc)). Noting, however, that courts have not been unanimous in their treatment of the entrapment defense, Dean Marcus recognized two competing approaches to the problem:
The traditional, and prevailing, view has been that a defendant cannot raise inconsistent defenses in the entrapment area. Courts consistently hold that “it would be inconsistent and confusing to allow a defendant to contend in one breath that he did not commit the crime, and in the next breath that he was entrapped into committing it.”
Id. at 229 (citing United States v. Sears, 343 F.2d 139, 143 (5th Cir.1965)). Other jurisdictions, however, do not accept this view, holding that a defendant “may deny [committing] every element of the crime charged yet properly allege that such acts as he did commit were induced by law enforcement officers.” Id. at 230-31 (citing People v. Perez, 62 Cal.2d 769, 44 Cal.Rptr. 326, 401 P.2d 934 (1965)).
Nilsen follows the traditional and prevailing view. Comparing Nilsen and Mathews, Nilsen holds that the defendant must plead, “I did it, but I was entrapped,” while Mathews holds that the defendant may plead, “I didn’t do it, but if I did, I was entrapped.” Although Mathews and Nil-sen both have defects and advantages, we believe that Nilsen is the better approach for two reasons.
First, the Mathews rule fosters perjury and more litigation. Under Mathews, a defendant may take the stand and testify that he did not do the act. The jury is instructed not only on the elements of entrapment but the elements of the crime itself. To allow a defendant to testify as to two defenses that cannot both be true is equivalent to sanctioning a defendant’s perjury. Mathews, 485 U.S. at 72, 108 S.Ct. at 891. (White, J., dissenting).
Second, allowing inconsistent defenses may confuse the jury. What must the jury think when the defendant testifies that he had nothing to do with the sale of narcotics and then the defendant’s attorney tells the jury that, yes, the defendant did commit the crime but was entrapped? As Justice White noted in his dissent in Mathews:
Finally, even if the Court’s decision does not result in increased perjury at criminal trials, it will—at the very least—result in increased confusion among criminal juries. The lower courts have rightly warned that jury confusion is likely to result from allowing a defendant to say, “I did not do it” while his lawyer argues “He did it, but the government tricked him into it.”
*137Id. We agree with the dissent in Mathews. The entrapment defense “is a relatively limited defense,” available only to defendants who have “committed all the elements of a proscribed offense.” Mathews, 485 U.S. at 71, 108 S.Ct. at 890. When a defendant testifies that he did not commit the elements of the offense charged, the entrapment defense is not a plausible alternate legal theory of the case. Id. at 71, 108 S.Ct. at 891. Entrapment is a proper defense under these circumstances only if the accused is lying. We do not believe that the defendant has a right to lie at trial or a right to solicit his attorney’s aid in executing such a defense strategy. See Nix v. Whiteside, 475 U.S. 157, 173, 106 S.Ct. 988, 997, 89 L.Ed.2d 123, 138 (1986) (right to counsel includes no right to have a lawyer who will cooperate with planned peijury). Similarly, the entrapment defense is not available when a defendant who does not testify (as here), does not otherwise present to the jury some evidence of his admission of the elements of the crime. Nilsen, 134 Ariz. at 432, 657 P.2d at 420. Requiring a trial court to entertain an entrapment defense when the defendant has not admitted all elements of the crime does not serve the cause of criminal justice.
V. CONCLUSION
Requiring a defendant to admit the elements of the crime before pleading entrapment may not prevent defendants from committing perjury or the jury from being confused. Allowing inconsistent defenses, however, will encourage perjury rather than chill it. We believe that a defendant’s testimony will be more truthful and less confusing when he says, “I did it but I was entrapped,” than if he says, “I didn’t do it, but if I did, I was entrapped.” After all, we still must determine the truth, and we should not encourage practices that detract from that purpose.
The courts of appeals’ decisions are approved. The trial courts’ rulings are affirmed.
MOELLER and CORCORAN, JJ., concur.. We also granted review on the question of retroactive or prospective application of our decisión. Because we do not change the existing law in Arizona, we need not consider this question.
