                         OPINION

CLIFTON, Circuit Judge:

   Ruben Fernando Barragan-Lopez’s petition for review
presents the question whether an Arizona conviction for solic-
itation to possess at least four pounds of marijuana for sale,
in violation of Ariz. Rev. Stat. § 13-1002(A) and (B)(2), and
§ 13-3405(A)(2) and (B)(6), constitutes a crime involving
moral turpitude for the purposes of 8 U.S.C.
§ 1227(a)(2)(A)(i). We hold that it does. Accordingly, we
deny the petition for review.

I.   Background

  Barragan-Lopez is a native and citizen of Mexico. After
entering the United States without inspection or admission in
2002, his status was adjusted and he became a lawful perma-
nent resident of the United States on June 24, 2003.
15106             BARRAGAN-LOPEZ v. MUKASEY
   After being charged with violating various Arizona crimi-
nal laws, Barragan-Lopez signed a plea agreement on July 13,
2004, in which he pled guilty to, inter alia, “SOLICITATION
TO POSSESS MARIJUANA FOR SALE IN AN AMOUNT
OVER THE STATUTORY THRESHOLD, A CLASS 4 FEL-
ONY, in violation of A.R.S. §§ 13-1002, 13-3405(A)(2), 13-
3405(B)(6), 13-3401, 13-301, 13-302, 13-303, 13-304, 13-
701, 13-702, 13-702.01 and 13-801, committed on or about
December 17, 2003.” Barragan-Lopez was convicted of that
offense and sentenced to a term of imprisonment of one year.

   Barragan-Lopez was served a Notice to Appear on Febru-
ary 24, 2005, which alleged that he was “convicted in the
Superior Court of Arizona, Maricopa County, for the offense
[of] SOLICITATION TO POSSESS MARIJUANA FOR
SALE IN AN AMOUNT OVER THE STATUTORY
THRESHOLD, a class 4 felony.” Based on that conviction,
the Notice charged Barragan-Lopez as “subject to removal
from the United States pursuant to . . . [s]ection
237(a)(2)(A)(i) of the Immigration and Nationality Act, as
amended, [because he had] been convicted of a crime involv-
ing moral turpitude committed within five years after admis-
sion for which a sentence of one year or longer may be
imposed.”

   Barragan-Lopez disputed the charge of removability,
claiming that his conviction for solicitation to possess mari-
juana for sale was not a conviction for a crime involving
moral turpitude. Relying on Coronado-Durazo v. INS, 

(9th Cir. 1997), and Leyva-Licea v. INS, 

(9th Cir. 1999), Barragan-Lopez argued that the “crime
of solicitation is a separate and distinct offense from the
underlying offense” of possession. He therefore argued that,
because solicitation itself is not a crime involving moral turpi-
tude, solicitation to possess marijuana for sale could not be
such a crime either.

  The immigration judge (“IJ”) disagreed with Barragan-
Lopez, noting that, even though the preparatory solicitation
                 BARRAGAN-LOPEZ v. MUKASEY               15107
offense may be “separate and distinct” from the underlying
possession offense, “the Court is required to look at the
underlying substantive offense.” The IJ then concluded that
Barragan-Lopez was convicted of a crime involving moral
turpitude because “solicitation requires intent on the part of
the defendant . . . that the underlying crime be committed,”
and because the underlying crime of possession of marijuana
for sale is a crime involving moral turpitude. The IJ therefore
ordered removal.

   Barragan-Lopez appealed to the Board of Immigration
Appeals. The Board dismissed the appeal, concluding that
Barragan-Lopez’s conviction was for a crime involving moral
turpitude. The Board reasoned that, because the underlying
offense of possessing marijuana for sale constitutes “ ‘a crime
involving moral turpitude’ under the immigration laws,” and
because “the immigration law recognizes no distinction (with
respect to the moral turpitudinous nature of the crime)
between his inchoate offense and the completed crime,”
Barragan-Lopez’s conviction for solicitation to possess mari-
juana for sale was a crime involving moral turpitude.

   Barragan-Lopez timely petitioned this court for review of
the Board’s decision.

II.   Jurisdiction and Standard of Review

   “While we do not normally have jurisdiction to review ‘any
final order of removal against an alien who is removable by
reason of having committed certain criminal offenses,’ includ-
ing crimes involving moral turpitude, we are not barred from
hearing the constitutional claims or questions of law raised in
a petition.” Navarro-Lopez v. Gonzales, ___ F.3d ___,
No. 04-70345, 

, at *2 (9th Cir. Sept. 19,
2007) (citing 8 U.S.C. §§ 1252(a)(2)(C) and (D)) (brackets
and footnote omitted). Whether Barragan-Lopez’s prior con-
viction was for a crime involving moral turpitude is a question
of law, which we have jurisdiction to reach. See 

v. MUKASEY
   “We review de novo ‘whether a state statutory crime con-
stitutes a crime involving moral turpitude.’ ” 

v. Gonzales, 

, 1017 (9th Cir.
2005)).

III.    Discussion

   Barragan-Lopez contends that the Board erred in conclud-
ing that the Arizona offense of solicitation to possess more
than four pounds of marijuana for sale is a crime involving
moral turpitude. We disagree.

   The Immigration and Nationality Act “defines classes of
removable aliens and makes removable an alien who is ‘con-
victed of a crime involving moral turpitude within five years
. . . after the date of admission’ and ‘is convicted of a crime
for which a sentence of one year or longer may be imposed.’ ”
Notash v. Gonzales, 

, 696 (9th Cir. 2005) (quot-
ing 8 U.S.C. § 1227(a)(2)(A)(i)) (ellipses points in original).
“In determining whether a conviction constitutes a removable
offense, we apply the categorical approach, looking only to
the statutory definition of the offense.” 

(citing
Tokatly v. Ashcroft, 

, 620 (9th Cir. 2004)).

   [1] Under the categorical approach, a conviction is a crime
of moral turpitude if “the full range of conduct encompassed
by the statute,” including the least egregious conduct prose-
cuted under the statute, is a crime of moral turpitude. See
Quintero-Salazar v. Keisler, No. 04-73128, 

, at *2 (9th Cir. Oct. 9, 2007). We look at the specific
subsections of a statute that the petitioner is convicted under
to determine if it is a crime of moral turpitude. See 

   In this case, Barragan-Lopez was convicted under two sec-
tions: (1) Ariz. Rev. Stat. § 13-1002(A) (solicitation), and
(2) Ariz. Rev. Stat. § 13-3405(A)(2) (possession of marijuana
for sale). Section 13-1002(A) defines the offense of solicita-
tion as follows:
                  BARRAGAN-LOPEZ v. MUKASEY                15109
    A person . . . commits solicitation if, with the intent
    to promote or facilitate the commission of a felony
    or misdemeanor, such person commands, encour-
    ages, requests or solicits another person to engage in
    specific conduct which would constitute the felony
    or misdemeanor or which would establish the other’s
    complicity in its commission.

Ariz. Rev. Stat. § 13-3405(A)(2) defines the offense of pos-
session of marijuana for sale: “A person shall not knowingly
. . . [p]ossess marijuana for sale.” Because Barragan-Lopez
was convicted of soliciting possession of more than four
pounds of marijuana, he was convicted of a class 4 felony.
See Ariz. Rev. Stat. § 13-1002(B)(2) (“Solicitation is a . . .
[c]lass 4 felony if the offense solicited is a class 2 felony.”),
§ 13-3405(B)(6) (“A person who [possesses for sale] an
amount of marijuana having a weight of more than four
pounds is guilty of a class 2 felony.”)

   [2] Barragan-Lopez argues that, because the solicitation
offense is separate and distinct from the underlying posses-
sion offense, this court should not consider the underlying
crime in determining whether his prior conviction was for a
crime involving moral turpitude. But Barragan-Lopez was not
convicted for “solicitation” of unspecified criminal conduct.
He was convicted for soliciting possession of over four
pounds of marijuana for sale. We have previously looked to
underlying crimes in determining whether convictions for
inchoate offenses constitute crimes involving moral turpitude.
See, e.g., Goldeshtein v. INS, 

, 647 n.6 (9th Cir.
1993) (“a conspiracy to commit an offense involves moral
turpitude only when the underlying substantive offense is a
crime involving moral turpitude”); McNaughton v. INS, 

, 459 (9th Cir. 1980) (“Where the underlying, sub-
stantive offense is a crime involving moral turpitude . . . , con-
spiracy to commit such an offense is also a crime involving
moral turpitude.”) (citations omitted). We therefore consider
the underlying possession offense in determining whether
15110             BARRAGAN-LOPEZ v. MUKASEY
Barragan-Lopez pleaded guilty to a crime involving moral
turpitude.

   [3] Drug trafficking offenses, including possession of
unlawful substances for sale, generally involve moral turpi-
tude. See Atl. Richfield Co. v. Guerami, 

, 282
(9th Cir. 1987) (noting that possession of heroin for sale is a
“crime of moral turpitude”) (citing United States ex rel.
DeLuca v. O’Rourke, 

, 762 (8th Cir. 1954)
(“[T]here can be nothing more depraved or morally indefensi-
ble than conscious participation in the illicit drug traffic.”)).
The quantity inherent in Barragan Lopez’s conviction — four
pounds of marijuana — was too great to justify treating this
crime differently. By pleading guilty to solicitation to possess
at least four pounds of marijuana for sale, Barragan-Lopez
necessarily admitted that he had the specific “intent to pro-
mote or facilitate the commission of a [crime involving moral
turpitude].” See Ariz. Rev. Stat. §§ 13-1002(A); see also Atl.
Richfield 

. Accordingly, we hold that
Barragan-Lopez’s conviction for solicitation to possess at
least four pounds of marijuana for sale, in violation of Ariz.
Rev. Stat. § 13-1002(A) and (B)(2) and § 13-3405(A)(2) and
(B)(6), constitutes a crime involving moral turpitude for pur-
poses of 8 U.S.C. § 1227(a)(2)(A)(i). We do not address the
question that would be presented if Barragan-Lopez had been
convicted of solicitation to possess a very small quantity of
marijuana for sale, such as, for example, a single marijuana
cigarette at a party with personal friends.

   Barragan-Lopez points us to two cases that we conclude are
distinguishable from the present case. In Coronado-Durazo,
we were asked to determine “whether petitioner’s conviction
for solicitation to possess cocaine is a deportable offense
within the meaning of section 241(a)(2)(B)(i) of the Immigra-
tion and Nationality Act,” which provides that “any alien who
is convicted of ‘a violation of (or a conspiracy or attempt to
violate) any law or regulation . . . relating to a controlled sub-
stance’ may be 

. After noting
                  BARRAGAN-LOPEZ v. MUKASEY                15111
that “solicitation is a generic offense under Arizona law” and
that the “plain language of § 241(a)(2)(B)(i) limits convic-
tions for generic crimes that may result in deportation to con-
spiracy and attempt,” we held that “solicitation is not a
deportable offense under § 241(a)(2)(B)(i).” 

   Barragan-Lopez also directs us to 

, in which we decided whether a violation of Arizona’s
solicitation statute constituted an aggravated felony under 8
U.S.C. § 1101(a)(43)(B), which required that the violation
“(1) be punishable under the Controlled Substances Act, and
(2) qualify as a felony.” In that case, we concluded that solici-
tation to possess marijuana for sale is not an aggravated fel-
ony under 8 U.S.C. § 1101(a)(43)(B) because the Controlled
Substances Act “does cover attempt and conspiracy,” but not
solicitation. 

statutory provisions at issue in Coronado-
Durazo and Leyva-Licea, section 1227(a)(2)(A)(i) does not
list certain generic offenses (e.g., conspiracy or attempt) to the
exclusion of others (e.g., solicitation). Thus, the reasoning
applied in both cases — i.e., that, “where a statute listed some
generic offenses but omitted others, the statute covered only
the generic offenses expressly listed” — is inapplicable here.
See 

(citing 

). Additionally, in Coronado-Durazo and
Levya-Licea, we decided whether Arizona’s solicitation
offense constituted a crime “relating to a controlled sub-
stance” under 8 U.S.C. § 1251(a)(2)(B)(i), or an “aggravated
felony” under 8 U.S.C. § 1101(a)(43)(B), respectively. In nei-
ther case were we asked to determine whether solicitation to
possess more than four pounds of marijuana for sale is a
crime involving moral turpitude under 8 U.S.C.
§ 1227(a)(2)(A)(i). Coronado-Durazo and Leyva-Licea are
therefore distinguishable.

   Barragan-Lopez also argues that “the government’s posi-
tion still fails under the Rule of Lenity,” which requires courts
15112             BARRAGAN-LOPEZ v. MUKASEY
to construe ambiguities in deportation statutes in favor of the
alien. Montero-Martinez v. Ashcroft, 

, 1141
(9th Cir. 2002). Because Barragan-Lopez fails to establish
that any deportation statute at issue is ambiguous, we reject
this assertion. See Lisbey v. Gonzales, 

, 933 (9th
Cir. 2005).

   Finally, Barragan-Lopez contends that the government’s
“burden of demonstrating deportability by ‘clear, convincing,
and unequivocal evidence’ has not been met.” But at the
March 14, 2005, hearing before the IJ, Barragan-Lopez admit-
ted each factual allegation considered by the IJ and the Board
for removal. Barragan-Lopez’s own admissions constitute
clear, convincing, and unequivocal evidence, and therefore we
conclude that the government met its evidentiary burden of
demonstrating removability.

IV.     Conclusion

   We hold that a conviction for solicitation to possess at least
four pounds of marijuana for sale constitutes a crime involv-
ing moral turpitude for purposes of 8 U.S.C.
§ 1227(a)(2)(A)(i). We therefore uphold the Board’s decision
and deny the present petition for review.
