The only real hoop you have to jump through is to go through the online training course which takes about 30 minutes and is all about administration of the drug
I received my package today and feel it's important to have around with the current rise in opioid overdoses.
Their kit does not include CPR masks so I recommend purchasing some to keep with your doses. (Won't share a link due to Amazon boycott)
I would've bought some ages ago if I lived in a bigger city.
Apparently you can get Narcan from weed shops too. My father told me he scored some for free when he went a few days ago. I don't know why he got it, because he doesn't use opioids, but I guess it's good to have on hand in case someone else needs it.
