The court ruled in the case of Julie Eldred, who was jailed in 2016 after she tested positive for the powerful opioid fentanyl days into her probation on larceny charges. Eldred, who has severe substance use disorder, spent more than a week in jail after relapsing until her lawyer could find a bed for her at a treatment facility.
Eldred's lawyer argued before the high court in October that her client's substance use disorder made her powerless to control her desire to use drugs, and that jailing her effectively criminalized relapse -- which often happens in the recovery process. But the justices said the defendant's claims were based partly on untested science.
