Nasal spray “Narcan” (CREDIT: WINK News) Teachers in Lee County Schools started training to use Narcan in September. The Lee County School Board admits it hasn’t run into the issue on a school campus, but it is on hand if necessary. Each school will have at least three staff members trained to use the life-saving nasal spray. Narcan has also been approved in Collier County Schools after the sheriff said they’ve seen an increase in fentanyl seizures.
