Missed this a few days ago. Whether there is anywhere that overdose deaths are going down is a valid question.
I got the info I posted from this page:
https://www.drugabuse.gov/drugs-abuse/opioids/opioid-overdose-crisis
Which is kind of an exec summary that does not list comprehensive stats.
I found state-by-state reports here:
https://www.drugabuse.gov/drugs-abuse/opioids/opioid-summaries-by-state
I don't see anywhere that collects year to year data for every state in one place - there could be, I just didn't see it. You can pull up a page for each state.
Looking at my own state of MO, it has this chart:
8x increase in 16 years. Now MO is one of the states in red on the map, with the highest rates (over 15 per 100,000 per year), so maybe we should also pick some random states with the LOWEST rates and see what they did.
So, no, it's not going up everywhere. Based on this small sample, the best we are seeing is pretty flat in some states, with the occasional state (Montana) actually going down some in recent years but still higher than in 2000. This is based on a sample of 4 states so I'm generalizing. But it appears to be a crisis affecting certain areas but not the entire country equally.
