The factors which cause people to be increasingly vulnerable to addiction and suicide are largely socio-economic.
I disagree on the “largely” term. Some people are genetically prone to addiction, whether it’s alcohol, opioids or other pleasure stimulants. I’ve had dental and other surgery and been Rx opioids and they didn’t give me a buzz or even much pain relief. I threw them away and just went to Advil or similar over the counter pills. I’m a member of the flower child generation but didn’t do illegal drugs then as I knew the dangers weren’t worth trying them. Cheap wine or beer was enough to get a buzz and I knew when to stop before I got too drunk. I’m middle-class social-economic, my parents and religion taught me right from wrong.

I believe that there are many similar factors leading to addiction and suicide, but they are certainly two distinct and not entirely overlapping issues.
