Plenty of other people share responsibility.

The public often expects strong painkillers rather than dealing with extreme pain. You can request less extreme painkillers and use less than prescribed.

Doctors can’t directly measure pain so while the have an important role, they can’t do it alone.

On top of that drug companies had a strong incentive to change the culture around pain and succeeded.

The illegal drug market thrives via specific and changeable laws.

People doping illegal drugs have a direct moral responsibility to their customers, but frankly they are already breaking the law so you can only expect so much.

Illegal drug users often seek out stronger highs resulting in their deaths. Seeking treatment is a possibility for these users.
