In participants with a cocaine use disorder, ANOVA revealed significantly higher ESS scores among those defined as “poor sleepers” (with a PSQI score >5) when compared to those defined as “good sleepers” (with a PSQI score ≤5). In addition, poor sleepers reported using cocaine for more days out of the past 30 when compared to good sleepers. Interestingly, good sleepers reported …
