CHICAGO (AP) — Chicago now gives at-risk inmates the overdose-reversing drug naloxone upon their release from jail and Los Angeles is poised to follow suit, putting the antidote in as many hands as possible as part of a multifaceted approach to combatting the nation's opioid epidemic. The Cook County Jail in Chicago, which is the largest single-site jail in the country, has trained about 900 inmates how to use naloxone nasal spray devices since last summer and has distributed 400 of them to at-risk men and women as they got out.
