But you can't mainline oxycodone into everyone who claims to have chronic pain
You say this like it should be taken for granted, but honestly, with the amount of deaths we have from people overdosing on illegal fentanyl, it might be better at this point if we simply gave less-overdose-prone opioids to anyone who was addicted!
I am curious about your conclusion that "opiate deaths and suicide deaths due to chronic pain are in the same order of magnitude", though. According to my simple Googling, opioids are the cause of death for 21.7 per 100,000 people in the US, while suicide is only 14 per 100,000. So per your link, chronic pain suicide is about 10% of that, or 1.4 per 100,000. That means opioid deaths are about 10-15x more common, or am I missing something?
edit: I'm realizing my understanding of this debate is significantly out-of-date. So I apologize if anything I've written seems tone-deaf, that wasn't my intention.
