Abstract
Mandatory minimum sentencing provisions have been a feature of the US justice system since 1790. But they have expanded considerably under the war on drugs, and their use has expanded considerably under the Trump Administration; some states are also poised to expand drug-related mandatory minimums further in efforts to fight the current opioid epidemic. In this chapter I outline and evaluate three prominent arguments for and against the use of mandatory minimums in the war on drugs—they appeal, respectively, to proportionality, consistency, and efficiency. I ultimately defend the view that the use of mandatory minimums in the war on drugs is unjust.
