Background

In November 2022, law enforcement conducted controlled buys and a search warrant at the defendant’s home, seizing methamphetamine, firearms, and cash. The defendant pleaded guilty to possession with intent to distribute methamphetamine and possession of a firearm after a felony conviction. The district court imposed a 180-month sentence of imprisonment and a three-year term of supervised release.

The court’s reasoning

The court reviewed the district court’s calculation of the sentencing guidelines range de novo. It found no error in treating the defendant as responsible for actual methamphetamine rather than a mixture, noting the guidelines distinguish between the two. The court also held that while district courts may vary downward based on policy disagreements, they are not required to do so.

What it means going forward

The decision reinforces that sentencing courts may rely on the purity of methamphetamine for guideline calculations and are not obligated to adjust sentences based on arguments that the distinction between pure and mixed drugs is arbitrary.
