On July 18, 2014, the U.S. Sentencing Commission amended the federal Sentencing Guidelines to retroactively reduce penalties for most drug offenses. Just over 51,000 inmates (almost 25% of the total federal prison population) will be eligible to have their sentences reduced. The Sentencing Commission estimates that these inmates will receive an average reduction of just under 2 years. At an average annual incarceration cost of approximately $30,000 per prisoner, the savings to the federal budget from this amendment will be approximately $2.5 billion dollars. A win-win for prisoners and taxpayers.
