They are still severely under prescribed in nations across the world. To the point that they are not available at all in many countries due to puritanical lobbying. Which means people across the globe are still suffering an absolute horrible fate, despite how easy it is even for a developing country to produce pain medication. The world still hasnt recovered from the last US crusade against pain medication, so i am more then a bit worried about what happens in the US right now. The fact that large parts of the world today have worse pain management options available to their population then what was available in the middle ages should scare you a lot more then some guy having fun with his medication.
People misusing pain medication is a small price to pay to have pain medication available for people who need it. There wont be an optimal solution by pushing down on pharma companies and doctors, it will be quite a lot worse then today.
To put it simply, if you are lobbying to combat the so called "opioid crisis" you should think damn hard about the consequences of your actions. Because if or better when there is another backlash peoples suffering caused by a lack of pain medication will be on your hands.
