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.
