Some people have some back pain / other pain and, if they're out of a job (commonly factory jobs) they go on disability (almost as a form of welfare), and will often get meds for their pain (this is the fault of doctors, pharma companies, generally medical culture emphasizing quick fix Rx vs other methods of dealing with pain).

Obviously these drugs are addictive, and if you're already in a bad place bc you went from a great stable job in your 30s to pseudo-welfare in your 50s, you're more vulnerable to addiction
