" Less than half (44.7%) of all drug offenders sentenced in fiscal year 2016 were convicted of an offense carrying a mandatory minimum penalty, which was a significant decrease from fiscal year 2010 when approximately two-thirds (66.1%) of drug offenders were convicted of such an offense. In fact, the number of offenders convicted of a drug mandatory minimum penalty has decreased by 44.7 percent since fiscal year 2010, falling from 15,831 offenders to 8,760 such offenders in fiscal year 2016.
" The downward trend in the prevalence of offenders convicted of such penalties occurred across all drug types, but the largest decrease occurred in the context of crack cocaine offenders. Following the passage of the Fair Sentencing Act of 2010, the percent of crack cocaine offenders convicted of an offense carrying a mandatory minimum penalty has fallen from 80.1 percent in fiscal year 2010 to 46.6 percent in fiscal year 2016."
