LARSEN, Circuit Judge. Kejuan Pharrell Carter pleaded guilty to distributing methamphetamine and was sentenced to 108 months’ imprisonment. Carter challenges the procedural reasonableness of that sentence, arguing that the district court failed to address his policy argument for a downward variance from the advisory Sentencing Guidelines range. Carter is not entitled to relief because he either waived his right to bring this challenge or invited the alleged error, and no manifest injustice will result from declining to consider his challenge. We AFFIRM.
