Silly me. I thought the result of “OD’ing” was that the person who OD’d was dead.
I mean, pretty much anyone who does illegal drugs takes too much (an overdose) of whatever drug they’re doing.
I’m pretty sure the headline writer wanted people to infer that. She actually didn’t really OD, and the paramedics who checked on her didn’t take her to the hospital. Like you, I think of OD like drowning or electrocution. You’re dead.
