You’re wildly incorrect, nobody involved was a vet.

Barry Marshall shared that Nobel and is a Doctor. https://en.wikipedia.org/wiki/Barry_Marshall

Robin Warren received his M.B.B.S. an undergraduate degree focused on medical research. https://en.wikipedia.org/wiki/Robin_Warren He worked at: “SA Pathology, (formerly the Institute of Medical and Veterinary Science (IMVS)), is an organisation providing diagnostic and clinical pathology services throughout South Australia for the public health sector.” https://en.wikipedia.org/wiki/SA_Pathology

So whatever source you read that misinformation from is not trustworthy.

> Opioids where addictive

Hindsight bias here. We don’t want medical professionals to discard new information in favor of older treatments. There’s no way doctors can on their own replicate the medical research linking Ulcers with a bacterial infection and independently judge oxycodone’s effectiveness, and a dozen other drugs etc. Extended-release (ER) oxycodone was literally a new drug and described as not having the same issues associated with other Opioids on labeling approved by the FDA.

The crazy thing is how effective this all was. Medical schools were teaching students to hand out more opioids.
