Under the agreement, Irish drug company Adapt Pharma will provide two doses of Narcan nasal spray to any New Hampshire high school that wants it.
The company is working in collaboration with the Clinton Foundation. It offered free Narcan to all U.S. high schools in January.
State Health and Human Services Commissioner Jeff Myers says giving schools the option of stocking the drug at no cost makes sense.
"There is a potential to have a need in the school setting, given the opioid epidemic in this state, and so this was an opportunity that came along and we wanted to take advantage of it at make it available on a voluntary basis."
Right now, Nashua high schools stock Narcan. It's also been approved in Berlin. Manchester's school board is expected to vote on it next week.
Putting 2 doses of Narcan in every New Hampshire high school in the state would cost about $13,000.
