Do you really think that Michael Jackson and Prince wanted to "check out"?

My assessment is that if even people at that level of wealth and success can get addicted to opioids and die, pretty much anyone can.

Addiction, whether alcohol, drugs, cigarettes, etc., is something that is a genuine medical issue needing treatment. Thankfully, the medical community seems to be shaking off the social stigma about addiction and treating it properly now, but progress has been very slow.
