Early this summer more than 80 people were being held in county and city jails in Maryland, even though courts had said they needed in-patient mental-health care. Now the number is about a dozen. We ask Van T. Mitchell, Maryland Secretary of Health and Mental Hygiene, what changes have made it more likely detainees will get mental-health services, and what challenges lie ahead. Does the state have enough mental-health workers, and enough beds to meet its obligations? We also talk about Maryland’s growing epidemic of overdose deaths related to heroin and fentanyl.
