It was a letter to the editor, not a study. Five paragraphs. One hundred and one words. Published in the New England Journal of Medicine on January 10, 1980, it bore the title 'Addiction Rare in Patients Treated with Narcotics.' The authors, Jane Porter and Hershel Jick, were summarizing data from hospital records, noting that of nearly 12,000 patients given narcotics, only four documented cases of addiction arose. The context was narrow, specific to hospitalized patients under close supervision. The letter contained crucial caveats. It was an observation, not a conclusion meant for broader clinical practice.
But a fact, once published, can be severed from its context. In the 1990s, pharmaceutical representatives began citing this letter as definitive proof that the new generation of long-acting opioids carried a minuscule risk of addiction. The '0.04%' figure was stripped of its original, confined setting and presented as a universal truth. It was wielded to reassure doctors, to dismantle decades of medical caution. The letter’s original, limited intent was lost, its nuance flattened into a marketing slogan. A small, cautious footnote in medical literature was reframed as a sweeping permission slip, helping to open the floodgates for prescriptions that would, over decades, lead to hundreds of thousands of deaths. The power of a scientific fragment lies not only in its data, but in the story others choose to build around it.
