This week, I’ve been covering Rhode Island’s efforts to change the way we deal with substance abusers who frequent the emergency room (part 1, part 2). I talked to emergency dispatchers, firefighters, addiction treatment specialists, public officials, and more.

Providence Public Safety Commissioner Steven Pare wants you to call 911 if you're having a real emergency. But he says most calls these days - more than 75 percent - aren't emergencies. And that's stretching city resources thin.

"Look, every time we send a rescue out on average to pick up a person anywhere in the city and transport them it's costing the taxpayer $550 dollars."
