In my previous professional life, I witnessed the slow, painful death of a young person in intensive care with liver failure, she had intentionally overdosed on paracetamol. Just one example of the many overdoses witnessed in my four plus decade career. I witnessed physical and psychological dependence upon paracetamol in many people, not just for pain relief. It does happen!
Paracetamol is toxic to your liver! Too many people rely upon this chemical, as the one and only go to medicine, without realising just how dangerous it is! Unintentional overdose does happen, as well as intentional.
As a retired professional nurse, I am all for regulation!
