What is your supposition here? That addicts are keeping narcan around just in case? That good friends of addicts are standing by with the spray in case it is needed? That your local opium den had staff with it on hand?

Narcan should be available, but short of a few users that know they need to keep it around, I don’t buy that making it available has meant a significant change in total outcomes because of timely deployment.

First responders would carry narcan or equivalent. I am sure it is readily available in areas where people are dying daily from overdoses.

See as you can buy narcan out of a vending machine now, yes it's wider distribution probably has a downward effect on opioid deaths.

Some of those ... absolutely, yes?

You might have got some at a rehab centre, or someone might live with a non-addict friend or partner. Community outreach workers (in cities that have embraced this stuff) might carry some around to administer.

I would be surprised if widespread availability to Narcan didn't decrease ODs.

Yes to all of the above. I knew of addicts who managed to get their hands on it many years ago when it required a prescription. Most weren't that resourceful though.
