You can because some poorer countries don't have an opiod epedimic. For example, opiod use is higher in West Virginia than Mexico. Certainly true that comparative poverty plays a role but we need to first hold accountable those directly responsible. http://geocurrents.info/wp-content/uploads/2012/05/Per-Capit...
Overprescribing is undoubtedly a key part of the problem, but so is poverty. The opioid epidemic is having a vastly disproportionate effect on poor communities, in large part because poor people are vastly disproportionately likely to suffer from chronic pain. Doctors didn't cause the crack epidemic in the 80s. We can't isolate any single factor, but must consider the problem in a holistic manner. Fixing the problem…
The second is a tendency to prescribe opiods to poor populations rather than focusing on less addictive medications. Further, non chronic pain can transform into chronic pain as Opiod uses/addiction increases pain sensitivity.
Combine the above and poor healthcare more directly links to Opiod addiction than you're suggesting.
EX: Mildly Injured > no medical care > working while Injured due to lack of sick leave > more significant problem > prescribed Opiod's vs surgery > addiction.
