NALBANDIAN, Circuit Judge. Antwaun Allen pleaded guilty to possessing methamphetamine with intent to distribute. At sentencing, he sought a downward variance from his Guidelines range, raising the government’s role in his offense, policy critiques of the Guidelines’ treatment of meth purity, as well as other mitigating offense and character traits. The district court sentenced Allen to 108 months, at the bottom of his Guidelines range.

Allen makes three arguments on appeal. First, Allen claims the sentence is procedurally unreasonable because the district court failed to address the government’s provocation of his offense. Second, Allen claims that the sentence is procedurally unreasonable because the district court impermissibly ceded its sentencing discretion to Congress. Finally, Allen argues the sentence is substantively unreasonable because the district court exclusively relied on the meth’s weight and purity, as reflected in the Guidelines, to the neglect of his “whole person.” Because we conclude his three claims lack merit, we AFFIRM.
