” I recall a story about a deputy who nearly died just from inhaling vapors off a stash he found in a suspect’s vehicle.”
That would be false. There’s a lot of hysterical syncope involved when LE meets up with a drug scene.
After further thought on the matter, I didn't read the story, I saw a video on youtube that showed a senior officer trying to help a rookie who had accidentally been exposed to fentanyl and suddenly collapsed.
The senior officer gave him naloxone or narcan and saved his life.
It looked real to me.
