¶1Ronald Todd Johnson appeals his conviction for delivery of a controlled substance claiming the information charging him with the crime was constitutionally defective because it omits the essential element of guilty knowledge. The information stated in pertinent part:
[T]he defendant, on or about the 8th day of February, 1990, did unlawfully deliver a controlled substance, to wit: cocaine; proscribed by RCW 69.50.401(a), a felony.
¶2At trial Johnson's defense was entrapment.
¶3Johnson claims the charging document/information was insufficient because it only alleges that he "unlawfully" delivered cocaine and did not specify that he knew the identity of the substance delivered.
¶4In State v. Kjorsvik, 117 Wn.2d 93, 812 P.2d 86 (1991), the Supreme Court held that all essential elements of a crime, statutory or court imposed, must be included in the information in order to give a defendant proper notice of the nature and cause of the accusation against him or her. The recent case of State v. Johnson, 119 Wn.2d 143, 829 P.2d 1078 (1992) upheld the holding in State v. Boyer, 91 Wn.2d 342, 588 P.2d 1151 (1979), that although the statute does not expressly require any intent for simple delivery, " 'guilty knowledge, an understanding of the identity of the product being delivered, is a part of the crime.'" Johnson, 119 Wn.2d at 146 (quoting Boyer, 91 Wn.2d at 344). See State v. Cleppe, 96 Wn.2d 373, 635 P.2d 435 (1981) (guilty knowledge is an implicit element of the crime of "delivery", but not simple "possession", of a controlled substance), cert. denied, 456 U.S. 1006 (1982). See also State v. Sims, 119 Wn.2d 138, 142 n.1, 829 P.2d 1075 (1992).
¶5When a defendant raises a challenge to an information for the first time on appeal, the information is reviewed under a 2-prong test:
(1) do the necessary facts appear in any form, or by fair construction can they be found, in the charging document; and, if so, (2) can the defendant show that he or she was nonetheless actually prejudiced by the inartful language which caused a lack of notice?
¶6(Footnote omitted.) Kjorsvik, 117 Wn.2d at 105-06.
¶7*938The defendant relies on State v. Kitchen, 61 Wn. App. 915, 812 P.2d 888, review denied, 117 Wn.2d 1019 (1991), which held that the information there contained nothing to imply the defendants knew the identity of the substance delivered. In Kitchen, as to knowledge, the information only charged, "you delivered a controlled substance". Kitchen, at 917. The facts and wording in the Kitcheninformation are different from those in this case. Here, "unlawful" delivery was alleged.
¶8There is precedent for construing the term "unlawfully" as sufficient to withstand a challenge to an information where that challenge is raised for the first time on appeal. The Washington State Supreme Court has held "unlawfiilly" sufficient to allege intent, unless there is prejudice to the defendant. See, e.g., Kjorsvik, 117 Wn.2d at 110-11. Additionally, despite its reaffirmation of State v. Boyer, supra,the reasoning of the court in Simsis analogous to the circumstance here. Use of the word "unlawfully" necessarily implies guilty knowledge that the delivered substance is a controlled substance under the statute. Given the Kjorsvikrule of liberal construction we think it enough to pass the first test established in Kjorsvik. In Johnson, the Supreme Court held, "We do not, therefore, hold 'unlawfully', standing alone, will never be enough to allege knowledge." Johnson, 119 Wn.2d at 148-49.
¶9We grant that the wording of the information, using only the word "unlawfully", is not particularly "artful". However, Johnson must meet the second prong of the Kjorsviktest by proving this omission was prejudicial to his defense. It is only those charging instruments which fail to set forth an essential element of a crime in such a way that a defendant is not afforded notice of the illegal conduct and the crime for which he is charged that require dismissal. State v. Hopper, 118 Wn.2d 151, 155-56, 822 P.2d 775 (1992).
¶10In the case before us, Johnson did not even allege prejudice. His defense was entrapment. An independent review of *939the record shows Johnson admitted delivering cocaine.
¶11For the above reasons, the conviction is affirmed.
¶12Pekelis, A.C.J., and Coleman, J., concur.
¶13 Johnson acknowledged that the substance he delivered was, in fact, cocaine. Johnson testified: "They knew exactly where I had gotten the coke that I gave them, . . .".
