The LA Times ran an investigation into Perdue Pharma's claim[1] and the article is incredibly disturbing. This is the killer quote:
> "More than half of long-term OxyContin users are on doses that public health officials consider dangerously high, according to an analysis of nationwide prescription data conducted for The Times."
Perdue Pharma has been lying about the 12-hour pain relief effect for decades. They wanted to dominate the 12-hour pain relief market. Whenever a doctor prescribed for a smaller interval of time, Perdue screamed bloody murder and sought to "refocus" doctors at all cost on the "12-hour rule" to ensure the drug stays in the 12-hour market share. To "refocus" doctors, Perdue Pharma tells doctors to prescribe stronger doses, rather than more frequent ones, and this leads to serious problems with reliance.
The evil here isn't that the drug is addictive but that doctors and pharmaceutical companies prescribe it despite the known side effects. It's almost unheard of outside the US.
This thing is known to be this addictive. That's basically only prescribed in exceptional cases elsewhere in the world. Basically it's not prescribed to otherwise healthy people who only suffer from pain (back pains, surgery pains etc). It's only prescribed to terminally ill people. Because it's better to use a slightly less potent painkiller and be in slightly more pain, than to be addicted to an opioid.
> when it doesn’t last, patients can experience excruciating symptoms of withdrawal, including an intense craving for the drug.
> Even before OxyContin went on the market, clinical trials showed many patients weren’t getting 12 hours of relief.
> OxyContin’s market dominance and its high price — up to hundreds of dollars per bottle — hinge on its 12-hour duration. Without that, it offers little advantage over less expensive painkillers.
> Purdue tells doctors to prescribe stronger doses, not more frequent ones, when patients complain that OxyContin doesn’t last 12 hours.
> Research shows that the more potent the dose of an opioid such as OxyContin, the greater the possibility of overdose and death.

$500k is a huge amount in Arizona politics.
For advanced cancer pain, oxycontin is effective and the rates of addiction are very low. Patients can't wait to get off it usually if the pain improves. There are likely to be many physiological and psychological factors explaining these differences.
"Advanced cancer pain" and "pain improves" [to a level where withdrawal seems like a good idea] seem like things that rarely go together. I could see people getting off of oxycontin to go onto stronger painkillers in hospice, but that feels like a very different thing to me.
As for a citation, well nobody has done a study on that specific point, I'm talking from my experience of 500 or so patients.
