'It's a no-brainer': Rising adolescent overdoses prompt calls for schools to stock naloxone

School nurse Katie Straub felt the weight of each second go by as she waited for paramedics to arrive. A student had overdosed on opioids, and the school didn't have naloxone, a drug that counteracts the effects of an opioid overdose.

"It was horrendous," said Straub, a nurse for Tucson Unified School District, the largest school district in Tucson, Arizona. "Nothing feels worse than standing by watching, not really able to do anything."
