Sure, but opioids are also a cheap solution to loneliness and to a chronic feeling of alienation and of "not belonging" caused by living in a society optimized for individual freedom and economic efficiency. I have yet to see reasons in this comment section to believe that access to healthcare specifically is the human need whose lack is driving most of the cases addiction in the US.

Most young adults have no pressing need for healthcare except possibly birth-control pills for the young women (since those require a prescription in the US) and if the millions of young adults in the US who have become addicts during this crisis had unmet health-care needs at a significantly higher rate than their counterparts who did not become addicts, addiction researchers would almost certainly have noticed by now, and I probably would've heard about it from journalists who cover the issue.
