an important thing to know about narcan is that there's one dose per package! there's no test spritz. don't try it out to see if it's working if you need to administer it to someone--if you spray it to see if it works, you just lost your dose. just stick it up their nose and spray, one and done. there is no danger in giving naloxone to someone who doesn't need it, and it works immediately so people should feel confident in their ability to use this and potentially save someone's life. naloxone is about as close to a miracle drug as it gets.
