MAY, Judge.
[1] Aadil Ashfaque appeals the denial of his motion to dismiss Count I, Class D felony dealing in a synthetic drug1 and [185]*185Count II, Class D felony possession of a synthetic drug.2 He presents multiple issues for our review, one of which we find dispositive: whether, at the time of Ash-faque’s alleged offenses, Ind.Code § 35-48-4-10(a), which prohibited dealing in a synthetic drug, and Ind.Code § 35-48-4-11, which prohibited possession of a synthetic drug, were unconstitutionally vague when the synthetic drug alleged to have been dealt in or possessed was not listed in the relevant provisions of the Indiana Code and could be found only in the Pharmacy Board Regulations?
[2] We reverse and remand.
Facts and Procedural History
[3] On May 8, 2013, the State charged Ashfaque with offenses including Class D felony dealing in a synthetic drug and Class D felony possession of a synthetic drug following a traffic stop during which XLR11 was discovered in Ashfaque’s possession. On June 4, Ashfaque filed a motion to dismiss the dealing and possession counts. The trial court denied Ashfaque’s motion. The trial court certified the issue for interlocutory appeal and we accepted jurisdiction.
Discussion and Decision
[4] Generally, we review the denial of a motion to dismiss for an abuse of discretion, McCown v. State, 890 N.E.2d 752, 756 (Ind.Ct.App.2008), while taking the facts stated in the charging information as true. Delagrange v. State, 951 N.E.2d 593, 594 (Ind.Ct.App.2011). However, when, as here, the denial rests on the trial court’s interpretation of a statute, we review the decision de novo. McCown, 890 N.E.2d at 756. The trial court denied Ashfaque’s motion to dismiss without findings of fact or conclusions of law.
[5] Our Indiana Supreme Court stated in Broum v. State:
A challenge to the validity of a statute • must overcome a presumption that the statute is constitutional. State v. Lombardo, 738 N.E.2d 653, 655 (Ind.2000). The party challenging the statute has the burden of proving otherwise. Brady v. State, 575 N.E.2d 981, 984 (Ind.1991). Due process principles advise that a penal statute is void for vagueness if it does not clearly define its prohibitions. Klein v. State, 698 N.E.2d 296, 299 (Ind.1998) (citing Grayned v. City of Rockford, 408 U.S. 104, 92 S.Ct. 2294, 33 L.Ed.2d 222 (1972)). A criminal statute may be invalidated for vagueness for either of two independent reasons: (1) for failing to provide notice enabling ordinary people to understand the conduct that it prohibits, and (2) for the possibility that it authorizes or encourages arbitrary or discriminatory enforcement. City of Chicago v. Morales, 527 U.S. 41, 56, 119 S.Ct. 1849, 1859, 144 L.Ed.2d 67, 79-80 (1999); Healthscript, Inc. v. State, 770 N.E.2d 810, 815-16 (Ind.2002). A related consideration is the requirement that a penal statute give a person of ordinary intelligence fair notice that his contemplated conduct is forbidden so that “no man shall be held criminally responsible for conduct which he could not reasonably understand to be proscribed.” Healthscript, Inc., 770 N.E.2d at 816 (quoting United States v. Harriss, 347 U.S. 612, 617, 74 S.Ct. 808, 812, 98 L.Ed. 989, 996 (1954)). In State v. Downey, 476 N.E.2d 121, 123 (Ind.1985), this Court emphasized that “there must be something in a criminal statute to indicate where the line is to be drawn between trivial and substantial things so that erratic arrests and convictions for trivial acts and omissions will not occur. [186]*186It cannot be left to juries, judges, and prosecutors to draw such lines.” Accordingly, the statutory language must “convey sufficiently definite warning as to the proscribed conduct when measured by common understanding.” Rhinehardt v. State, 477 N.E.2d 89, 93 (Ind.1985).
But a statute “is not void for vagueness if individuals of ordinary intelligence could comprehend it to the extent that it would fairly inform them of the generally proscribed conduct.” Klein, 698 N.E.2d at 299; accord Lombardo, 738 N.E.2d at 656. And the statute does not have to list specifically all items of prohibited conduct; rather, it must inform the individual of the conduct generally proscribed. Lombardo, 738 N.E.2d at 656. The examination of a vagueness challenge is performed in light of the facts and circumstances of each individual case. Id.
[6]868 N.E.2d 464, 467 (Ind.2007). Ash-faque was charged with Class D felony dealing in a synthetic drug and Class D felony possession of a synthetic drug. By the standard articulated in Brown, the 2012 versions of Ind.Code §§ 35 — 48-4-10(a) and 11 effective at the time of Ash-faque’s alleged offenses3 were unconstitutionally vague to the extent they rely on the term “synthetic drug”4 as defined by Ind.Code § 35-31.5-2-321(9).
[7]At the time Ashfaque allegedly committed the offenses, Ind.Code § 35-31.5-2-321 listed over sixty specific chemical compounds, and it included eleven sections regarding compounds “structurally derived” from other chemicals. Ind.Code § 35-31.5-2-321(1) — (8) (2012). It also stated a synthetic drug is “[a]ny compound determined to be a synthetic drug by rule adopted under IC 25-26-13-4.1.” Ind.Code § 35-31.5-2-321(9) (2012). Ind.Code § 25-26-13-4.1 (2012),5 which outlines the duties of the Pharmacy Board, states:
[8] (a) The board may adopt an emergency rule to declare that a substance is a synthetic drug.
[9] (b) The board may adopt an emergency rule declaring a substance to be a synthetic drug if the board finds that the substance:

[7]At the time Ashfaque allegedly committed the offenses, Ind.Code § 35-31.5-2-321 listed over sixty specific chemical compounds, and it included eleven sections regarding compounds “structurally derived” from other chemicals. Ind.Code § 35-31.5-2-321(1) — (8) (2012). It also stated a synthetic drug is “[a]ny compound determined to be a synthetic drug by rule adopted under IC 25-26-13-4.1.” Ind.Code § 35-31.5-2-321(9) (2012). Ind.Code § 25-26-13-4.1 (2012),5 which outlines the duties of the Pharmacy Board, states:
[8] (a) The board may adopt an emergency rule to declare that a substance is a synthetic drug.
[9] (b) The board may adopt an emergency rule declaring a substance to be a synthetic drug if the board finds that the substance:
[10] (1) has been scheduled or emergency scheduled by the United States Drug Enforcement Administration; or
[11] (2) has been scheduled, emergency scheduled, or criminalized by another state.
[12] (c) A rule adopted under this section becomes effective thirty (30) days after it is filed with the publisher under IC 4-22-2-37.1.
[13] (d) A rule adopted under this section expires on June 30 of the year following the year in which it is filed with the publisher under IC 4-22-2-37.1. ■
[14] (e) The board may readopt under this section an emergency rule that has expired.
[187]*187[15] Ashfaque argues Ind.Code § 35-31.5-2-821(9) and by implication Ind. Code § 25-26-13-4.1 are void for vagueness because “[a]n ordinary person cannot be required to follow and understand Indiana’s synthetic drug statutory maze.” (Br. of Appellant at 25.) We agree.
[16]Ashfaque’s charging information indicated he allegedly sold and possessed XLR11. That drug was not listed as a synthetic drug under Ind.Code §§ 35-31.5-2-321(1-8) on May 5, 2013, and nothing in the charging information indicates which Pharmacy Board emergency rule declared XTR11 a synthetic drug pursuant to the provisions in Ind.Code § 35-31.5-2-321(9) and Ind.Code § 25-26-13-4.1 (2012).6 A Pharmacy Board Emergency Rule, TSA Document # 12-493(E) (“Emergency Rule”), declared XLR11 a “synthetic substance” effective September 15, 2012.7 However, Ind.Code § 25-26-13-4.1 did not authorize the Pharmacy Board to declare something a “synthetic substance” in an Emergency Rule. Instead, the Emergency Rule permits the declaration of a substance as a “synthetic drug.” While that distinction might seem trivial, we believe the technical nature of this particular statute requires precision in language. For example, the Pharmacy Board may declare a new chemical concoction used to treat a deadly disease a “synthetic substance” and such a declaration would not invoke criminal consequences as does the Pharmacy Board’s declaration of something as a “synthetic drug.” See Brown v. State, 868 N.E.2d 464, 468 (Ind.2007) (noting alternate, legal uses for terms and the unconstitutional vagueness stemming therefrom). This linguistic confusion only adds to the vagueness of this statutory structure.
[17] To understand the charges against him, a person of ordinary intelligence would have to first find the definition of “synthetic drug” in Ind.Code § 35-31.5-2-321, determine the synthetic drug alleged to be illegal is not in the very long list8 in the statute, and finally look to Ind.Code § 25-26-13-4.1 to determine whether the drug may have been declared a synthetic drug by a Pharmacy Board Emergency Rule, the location of which is not specified in Ind.Code § 25-26-1341.1.
[18] The burden to meticulously weave through the labyrinth of criminal statutes, administrative code provisions, and not-yet-codified agency rules is inconsistent with the “process” our Founding Fathers believed we were due before being charged with criminal offenses. No person of ordinary intelligence could determine what he is prohibited to possess or deal by the term “synthetic drug” in Ind. [188]*188Code §§ 35-48-4-10(a) and 11, based on Ind.Code §§ 35-31.5-2-321(9) and 25-26-13-4.1. Therefore the portions of Ind.Code §§ 35-48-4-10(a) and 11 in effect at the time of Ashfaque’s alleged offenses are void for vagueness to the extent they rely on definitions, including unnamed substances “structurally derived” from other substances, found in Ind.Code §§ 35-31.5-2-321(9) and 25-26-13-4.1. See Health-script, 770 N.E.2d at 816 (holding the requirement that a person search through multiple statutes, then through the administrative code, “lacks the ‘sufficient definiteness’ that due process requires for penal statutes.”).
[19]We distinguish our holding here from those in two recent decisions, Kaur v. State, 987 N.E.2d 164, 168 (Ind.Ct.App. 2013) and Elvers v. State, 22 N.E.3d 824 (Ind.Ct.App.2014), both which declined to hold Ind.Code §§ 35-31.5-2-321(l)-(8) void for vagueness. In Kaur, the State charged Kaur with dealing and possession of AM-2201, which is specifically referenced as a synthetic drug under Ind.Code § 35-31.5-2-321(l)(QQ) (2012). Our court affirmed Kaur’s convictions, because Kaur’s constitutional arguments centered around Ind.Code § 35-31.5-2-321(9), which was not the definition of “synthetic drug” relied upon in Kaur’s convictions. Regarding Ind.Code § 35-31.5-2-321(9), we stated, “We leave for another day-and express no opinion on-the question of whether a person charged with possession of one of the Board-specified synthetic drugs would have a meritorious Article II, Section 1 argument.” Kaur, 987 N.E.2d 164, 169 n. 6. That day has come in the instant case, as Ashfaque was charged with dealing and possession of a synthetic drug, XLR11, which was specified as a “synthetic substance,” not a “synthetic drug” by a Pharmacy Board Emergency Rule.
[20] Additionally, in Elvers, we clarified our decision in Kaur, holding the use of scientific terminology in Ind.Code § 35-31.5-2-321 (l)-(8) does not render the statute unconstitutionally vague because the “novelty, complexity, and rapidly-evolving nature of synthetic drugs necessitates some scientific terminology in the law.” Elvers, 22 N.E.3d at 830. Elvers also acknowledged his case did not involve those synthetic drugs defined as part of Pharmacy Board Emergency Rules, but only those synthetic drugs “specifically identified in the statute [Ind.Code § 35-31.5-2-321].” Id.
[21] As Ind.Code §§ 35-48-4-10(a) and 11 form the basis for Counts I and II of Ashfaque’s charging information, and we hold those statutes are unconstitutionally vague based on the definition of “synthetic drug” set forth in Ind.Code § 35-31.5-2-321(9), the trial court erred when it denied Ashfaque’s motion to dismiss those charges.
Reversed and remanded.
