"Convictions for offenses carrying a drug mandatory minimum penalty were more likely to involve the use of a weapon, as evidenced by the application of a guideline enhancement for having a weapon involved in the offense (17.4% in fiscal year 2016 compared to 12.5% in fiscal year 2010) or a conviction for a firearms offense carrying a mandatory minimum (5.4% in fiscal year 2016 compared to 5.1% in fiscal year 2010). Similarly, convictions for offenses carrying a drug mandatory minimum penalty were also more likely to have resulted in bodily injury (4.1% in fiscal year 2016 compared to 1.9% in fiscal year 2010).
" Offenders convicted of such offenses were also more likely to have played a leadership role, as evidenced by application of a guideline adjustment for aggravating role (11.9% in fiscal year 2016 compared to 7.7% in fiscal year 2010), and were less likely to receive a mitigating role adjustment (12.1% compared to 16.3%).
" Consistent with increased likelihood of the above aggravating factors, the rate at which offenders convicted of an offense carrying a drug mandatory minimum penalty received relief through the statutory safety valve decreased from 35.1 percent in fiscal year 2010 to 30.0 percent in fiscal year 2016."
