Back in the early 90s, many ODs were rather combative (came back fighting) once Narcan was administered. With the frequency of opioid ODs and the advent of nasal Narcan, I have had questions about whether or not today's suspects / patients are again coming back in a combative, assaultive state after administration. Have been told the effect is softer; however that hasn't been what I've seen.
Strongly believe in making use of restrained detention prior to administration of the Narcan. Events like this only reinforce that - albeit for somewhat different reasons.
