Defendant-appellant William D. Killion pled guilty to one count of manufacturing 83.8 grams of Phenyl-2-Propanone (P-2-P) in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2. He was sentenced on April 5, 1991, to forty-six months imprisonment in accordance with the Sentencing Reform Act of 1984. He did not file a direct appeal. On July 11, 1991, Killion mailed a letter to the district court, claiming that the court erred in calculating his sentence and that he was wrongfully denied federal jail credit for time spent in state custody under a federal detain-er. In view of Killioris
pro se
status, the district court construed Killion’s letter as a motion for relief from an illegal sentence pursuant to 28 U.S.C. § 2255.

After considering the merits of the motion and the relevant precedents of our circuit, the district court, in a published decision, denied relief.
United States v. Killion,
I.
FACTS
Killion was charged with knowingly and intentionally manufacturing 83.8 grams of P-2-P with the intent of manufacturing amphetamines, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2. 2 While searching the premises occupied by Killion and his co-conspirators, the government found 66.3 grams of a yellow liquid in a glassware container, and in a separate container, 17.5 grams of a hardened dark brown substance. Drug Enforcement Agency laboratory reports revealed that the 66.3 grams of yellow liquid contained 52.9 grams of P-2P, and the 17.5 grams of dark brown substance contained an unquantifiable trace of P-2-P.
Killion was sentenced in accordance with 21 U.S.C. § 841(b)(1)(C) and § 2D1.1 of the United States Sentencing Commission Guidelines Manual (1991) (“the Guidelines”). In calculating Killion’s base offense level pursuant to § 2D1.1, the district court included the entire weight of the yellow liquid and the dark brown substance, 83.8 grams. Killion was assigned a total offense level of fourteen, which carries an imprisonment range of thir *929 ty-seven to forty-six months. He received a sentence of forty-six months imprisonment.
On July 11, 1991, Kilhion wrote a letter to the district court challenging the length of his sentence and contending that the court erroneously included the weight of unusable waste by-products `in determining his base offense level. 3 Specifically, Killion argued that the yellow liquid and the hardened dark brown substance contained waste by-products of the P-2-P manufacturing process that should not have been included in the court's calculations. From the 83.8 grams of the total mixture, Kiilion claimed, only 52.928 to 53.0 grams constituted P-2-P. Killion thus asserted that he should have been assigned a category twQlve under the Guidelines, based on 53.0 grams of P-2-P.
The district court, construing Killion's letter as a § 2255 motion for relief from an illegal sentence, rejected Killion's request for a reduced sentence. The court found that because the yellow liquid and dark brown substance contained a "detectable amount" of P-2--P, the entire amount of the mixture should be used for sentencing, in accordance with Tenth Circuit precedent. Id. at 1167.
II.
ISSUES PRESENTED
Killion's pro se briefs on appeal collectively state five issues: (1) whether the district court erred in calculating Killion's base offense level based on the entire weight of the mixture; (2) whether the Guidelines unconstitutionally classify P-2.-P as a Schedule II stimulant; (3) whether the district court erred in the application of the Guidelines due to the Guidelines' classification of P-2--P as a Schedule II stimulant; (4) whether the district court erred in applying the "mixture or substance containing a detectable amount" language for sentencing purposes; and (5) whether the district court erred in not applying the rule of lenity. The United States maintains that Killion is precluded from raising his second through fifth issues, as he did not specifically assert them at the district court level, and, in any event, the issues are nonmeritorious. Kilhion, however, contends that he raised these issues in his letter to the district court, but that the court nonetheless ignored them.
We appointed a federal public defender to file a supplemental brief and to present oral argument with respect to Killion's first issue only, as we are persuaded that this appeal, in fact, presents only a single issue. However, in view of Killion's pro se status prior to our appointment of the federal public defender, coupled with our review of the letter to the district court, we elect to address the merits of all five issues raised by Killion on this appeal.
III.
ISSUE 1
The first and principal issue presented by this appeal is whether the United States Supreme Court decision, Chapman v. United States, - U.S. -,
A. Dorrough & Callihan
Section 2D1.1 of the Guidelines concerns the calculation of base offense levels for drug offenses. Footnote * to § 2Dl.l(c) expressly states that “the weight of a controlled substance ... refers to the entire weight of any mixture or substance containing a detectable amount of the controlled substance.” U.S.S.G. § 2Dl.l(e) n. * (1991) (emphasis supplied). The plain language of the Guidelines, thus, requires that the entire weight of any mixture containing a detectable amount of a controlled substance be used in calculating a defendant’s base offense level.
In
Dorrough,
we adopted a literal interpretation of footnote * and held that the entire weight of a mixture containing P-2-P should be used in calculating a sentence under § 2D1.1, even though, in that case, the mixture mainly consisted of waste by-products.
4
Dorrough,
Similarly, in
Callihan,
we included the weight of waste by-products from the P-2-P manufacturing process in determining the total weight for purposes of the defendant’s sentence, even though the actual amount of P-2-P if separated would have called for a much lower sentence.
Callihan,
We are bound by the precedent of prior panels absent
en banc
reconsideration or a superseding contrary decision by the Supreme Court.
United States v. Spedalieri,
B. Chapman
Application note 1 to § 2D 1.1 of the Guidelines states that the term “[m]ixture or substance” as used in this guideline has the same meaning as in 21 U.S.C. § 841.” U.S.S.G. § 2D1.1. This leads us inexorably to Chapman, where the Supreme Court analyzed the meaning of the term “mixture or substance” in 21 U.S.C. § 841.
In
Chapman,
the petitioners were convicted of selling ten sheets of blotter paper impregnated with lysergic acid diethylamide (LSD) in violation of 21 U.S.C. § 841(a).
Chapman,
— U.S. at -,
On certiorari, the petitioners contended either that the statute should be interpreted to not include the weight of the carrier medium blotter paper or that the Court should hold the statute violative of due process.
Chapman,
— U.S. at -, -,
The Court found the petitioners’ interpretation of the statute, which would include only the net weight of the LSD, to be implausible given the history and structure of 21 U.S.C. § 841.

C. Split Among the Circuits
Since
Chapman,
the circuits have taken contrasting positions on the question whether a court may include
the
weight of materials such as waste by-products in calculating the weight of a mixture or substance containing a detectable amount of a controlled substance for sentencing purposes under § 2D1.1.
8
Most courts have fallen into two schools of thought, one of which centers its inquiry on whether the mixture at issue, like the blotter paper in
Chapman,
is usable, marketable and ready for ingestion or consumption; and another that does not rely on a usable/unusable distinction. The Supreme Court has acknowledged the split of authority among the circuits,
Sewell v. United States,
— U.S. -, -,
The Second, Third, Sixth, Seventh, Ninth, and Eleventh Circuits have adopted the approach that sentencing calculations under § 2D1.1 may not be based on the weight of mixtures containing unusable, unmarketable materials.
9
In holding that sentencing calculations should be based only on the weight of
usable
drug mixtures, these courts have distinguished the facts of
Chapman,
reasoning that the blotter paper in
Chapman
was usable, consumable and ready for wholesale or retail distribution, thus, it was rational to include its weight for sentencing purposes.
See, e.g., Acosta,
*933
The First
10
and Fifth Circuits, like the Tenth Circuit, however, have taken a contrary approach, expressly declining to overrule precedent establishing that the weight of unusable, unmarketable materials may be included for sentencing purposes under § 2D1.1.
See Walker,
— U.S. at -,
In
United States v. Walker,
The Fifth Circuit, in
United States v. Sherrod,
Further, in
United States v. Ruff,
D. The Tenth Circuit’s Position
Killion urges the Tenth Circuit to adopt the interpretation of Chapman of the majority of jurisdictions that have construed the Court’s “market-oriented” analysis. 12 Killion maintains that Chapman establishes that a drug distributor should be punished only for the usable, marketable total weight of a drug, including the cutting agent, dilutant, or carrier medium. He argues that this punishment is appropriate because these added products increase the distributor’s financial gain by *934 either increasing the amount sold, or converting the drug into marketable form. In addition, Killion alleges that waste by-products, that are merely disposed of, are not part of the "mixture or substance" for sentencing purposes because such materials constitute a "useless mixture."
In view of our clear precedent, as well as our interpretation of the decisions of the Fifth Circuit, we today again hold that so long as a mixture or substance contains a detectable amount of a controlled substance, its entire weight, including waste by-products of the drug manufacturing process, may be properly included in the calculation of a defendant's base offense level under § 2D1.1 of the Guidelines. Although we acknowledge the split of authority among the circuits with respect to this issue, we have consistently construed § 2D1.1 in this manner, and do not view Chapman as overruling Dorrough and Callihan. 13
In our view, the Chapman Court's discussion of the "market-oriented" approach was intended to be interpreted in the context of the question presented before the Court. The Court confronted the narrow question of whether the weight of a LSD carrier medium, blotter paper, may be included when determining sentences for trafficking in LSD. Chapman, - U.S. at -,
Furthermore, we note that the Court in Chapman expressly rejected the petitioners' argument that "the weight of the carrier should be excluded, the weight of the pure LSD should be determined, and that weight should he used to set the appropriate sentence." Chapman, - U.S. at -,
We think that petitioner's reading of the statute-a reading that makes the penalty turn on the net weight of the drug rather than the gross weight of the carrier and drug together-is not a plausible one. The statute refers to a "mixture or substance containing a detectable amount." So long as it contains a detectable amount, the entire mixture or substance is to be weighed when calculating the sentence.
Id. (emphasis supplied). Killion's interpretation of Chapman would require us to impose a sentence based on the net weight of the pure P-2--P found in the containers, rather than the gross weight of the mixtures, which contained a "detectable amount" of P-2--P. This is contrary to the Court's explicit statement above. Our view of Chapman, in which the entire weight of a mixture is used so long as it contains a detectable amount of a controlled substance, is consistent with the Court's analysis as well as footnote * to § 2D1.1(c). See id.; U.S.S.G. § 2D1.1(c) n.* (1991).
Finally, we note that Killion, in urging us to adopt an approach that relies upon a "usable/unusable" or "marketabfe/unmarketable" distinction, focuses primarily on the Chapman language: "Congress adopted a `market-oriented' approach to punishing drug trafficking, under which the total quantity of what is distributed, rather than the amount of pure drug involved, is used to determine the length of the sentence." Chapman, - U.S. at -,
In sum, we rule that the weight of waste by-products from the drug manufacturing process may be used in calculating a defendant's base offense level under § 2D1.1 of the Guidelines, provided, of course, that the mixture or substance contains a detectable amount of the controlled substance in question. In this case, the evidence showed that there was 52.9 grams of P-2--P in the yellow liquid, and an unquantifiable trace of P-2-P in the hardened dark brown substance. There was thus a "detectable amount" of P-2-P present in both containers, and the district court did not err in using the entire weight of the mixtures, including the weight of any waste by-products, in calculating Killion's base offense level.
IV.
ISSUES 2-S
Killion's second issue alleges that the Guidelines improperly and unconstitutionally classify P-2-P as a Schedule II stimulant. He contends that P-2-P is not a Schedule II stimulant because there is no scientific evidence available to establish that it is a stimulant. Kilhion's third issue asserts that the district court erred in applying the Guidelines due to this improper and unconstitutional classification of P-2-P.
We are unpersuaded that the Guidelines incorrectly and unconstitutionally classifly P.-2-P. P-2-P is a known and listed "immediate precursor" chemical used in the manufacture of amphetamine and methamphetamine. See 21 U.S.C. § 802(6), (22). We have held that amphetamine and methamphetamine are properly classified as Schedule II controlled substances. United States v. Lafoon,
V.
ISSUE 4
The fourth issue asserted by Killion is whether the district court erred in applying the "mixture or substance containing a detectable amount" language for sentencing purposes. Killion alleges that P-2-P offenses fall under 21 U.S.C. § 841(b)(1)(C), and that the above language applies only to those substances listed under 21 U.S.C. § 841(b)(1)(A)-(B).
We are unpersuaded by Killion's analysis. Section 841(b)(1)(C) sets forth penalties for violations involving controlled substance "in schedule I or II except as provided in sub-paragraphs (A), (B), and (D).. ." Nothing in § 841(b)(1)(C) negates the application of the "mixture or substance containing a detectable amount" language. Although the Guideline echoes the statute to some extent, it is not congruent. It is the Guideline we are construing and applying.
VI.
ISSUE 5
The fifth issue raised by Killion is whether the district court erred in not applying the rule of lenity. Killion contends that because of the lack of any statutory application of the phrase, "mixture or substance containing a detectable amount," the rule of lenity is applicable, and 21 U.S.C. § 841(b) and § 2D1.1 of the Guidelines must be construed in his favor. We hold that there is no reasons to resort
to the rule of lenity in this case. As noted in Chapman, the rule of lenity is not applicable unless there is a
"grievous ambiguity or uncertainty in the language and structure of the Act," such *936 that even after a court has “ ‘seize[d] every thing from which aid' can be derived’ ” it is still “left with an ambiguous statute.” “The rule [of lenity] comes into operation at the end of the process of construing what Congress has expressed, not at the beginning as an overriding consideration of being lenient to wrongdoers.”
Chapman,
— U.S. at -,
A straightforward reading of the statute and the Guideline at issue here, requiring that the weight of the entire mixture be included in determining a defendant’s base offense level so long as the mixture contains a detectable amount of the controlled substance in question, does not produce results so absurd or glaringly unjust as to raise reasonable doubt in regard to Congressional intent.

VII.
CONCLUSION
For the foregoing reasons, the ruling of the district court is AFFIRMED.
Notes
. Section 2255 authorizes a prisoner in custody to move the sentencing court to vacate or correct the sentence that was allegedly "imposed in violation of the Constitution or laws of the United States, or ... in excess of the maximum authorized by law....” 28 U.S.C. § 2255.
. Section 841(a)(1) provides:
(a) Except as authorized by this subchapter, it shall be unlawful for any person knowingly or intentionally—
(1) to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance; ....
21 U.S.C. § 841(a)(1).
. Killion also contended that the district court wrongfully denied him credit for time spent in state confinement and sought federal credit for the period between his arrest and his eventual return to state custody after federal prosecution. This appeal, however, does not challenge the credit for state custody claim.
. Dorrough was an appeal by a defendant convicted under 21 U.S.C. §§ 841, 846 and 18 U.S.C. § 2, of attempting to manufacture P-2-P and amphetamine; possession of P-2-P with intent to manufacture amphetamine; conspiracy to manufacture, possess, and distribute amphetamine; and traveling in interstate commerce in the aid and promotion of drug offenses.
. Footnote * to § 2D 1.1 at the time stated:
The scale amounts for all controlled substances refer to the total weight of the controlled substance. Consistent with the provisions of the Anti-Drug Abuse Act, if any mixture or compound contains any detectable amount of a controlled substance, the entire amount of the mixture or compound shall be considered in measuring the quantity.
U.S.S.G. § 2D1.1 n. * (1987) (emphasis supplied).
. We do not address and leave open for consideration the possibility that the split among the circuits with respect to this question has been addressed by the United States Sentencing Commission. See 58 Fed.Reg. 27, 148 (1993) (to be codified at U.S.S.G.App. C, no. 484) (proposed May 6, 1993). In the event that the Commission chooses to give previously sentenced defendants the benefit of a new Guideline, it is not our intention by this opinion to foreclose Killion from seeking appropriate relief.
. The Court defined "mixture” as:
A "mixture” is defined to include "a portion of matter consisting of two or more components that do not bear a fixed proportion to one another and that however thoroughly commingled are regarded as retaining a separate existence.” Webster’s Third New International Dictionary 1449 (1986). A "mixture” may also consist of two substances blended together so that the particles of one are diffused among the particles of the other. 9 Oxford English Dictionary 921 (2d ed. 1989).

as the dark brown substance in this case, involved mere "trace” amounts of P-2-P. The court noted that under the plain meaning of the Guidelines, which speak of "detectable," rather than "measurable” amounts of methamphetamine, the words "detectable amount" would include any quantity, however small, that can be discerned by accepted methods of analysis.
