            The Honorable Virginia M. Kendall, United States District Judge for
the Northern District of Illinois, sitting by designation.
United States v. McIntosh, 

(9th Cir. 2016). We have jurisdiction

under 28 U.S.C. § 1291, and we affirm.

      To prevail in a McIntosh hearing, Campbell must prove by a preponderance

of the evidence that he strictly complied with state medical marijuana laws. United

States v. Evans, 

, 1076–77 (9th Cir. 2019). We review de novo the

district court’s interpretation of state law. Asante v. Cal. Dep’t of Health Care

Servs., 

, 799 (9th Cir. 2018) (citing In re McLinn, 

,

1403 (9th Cir. 1984) (en banc)).

      The district court did not err in concluding that, because hash oil did not fall

within the safe harbor of the 2015 Montana Marijuana Act (“MMA”), Campbell

did not strictly comply with state law. See State v. Pirello, 

, 664–65

(Mont. 2012) (when marijuana plant material is “‘mechanically processed or

extracted’ in a manner that reduced it to resins”—as required to produce hash oil—

“the substance cease[s] to fall within the definition of ‘marijuana,’ and therefore

[cannot] be contained within the definition of ‘useable marijuana.’” (citation

omitted)).

      Campbell’s remaining challenges are unpersuasive. Although Campbell

argues he is entitled to the rule of lenity given the vagueness of the MMA, the

MMA is far from being grievously ambiguous. See United States v. Wyatt, 

, 1262 (9th Cir. 2005) (rule of lenity applies where “there is grievous


                                          2
ambiguity or uncertainty in the statute and when, after seizing everything from

which aid can be derived, [the court] can make no more than a guess as to what

[was] intended” (quoting United States v. Phillips, 

, 857, n. 39 (9th

Cir. 2004))); see also 

(declining to invoke the rule of

lenity). Because the legislature did not plainly intend the 2017 MMA amendments

to operate retroactively, they do not serve to clarify any alleged ambiguity

surrounding marijuana-infused products in the 2015 MMA. See Valles v. Ivy Hill

Corp., 

, 1079 (9th Cir. 2005); M.C.A. § 1-2-109 (2017).

      AFFIRMED.
