Purdue Pharma, which makes OxyContin, starting using the letter’s data to say that less than one percent of patients treated with opioids became addicted. Pain specialists routinely cited it in their lectures. Porter and Jick’s letter is not the only study whose findings on opioid addiction became taken out of context, but it was one of the most prominent. Jick recently told the AP, “I’m essentially mortified that that letter to the editor was used as an excuse to do what these drug companies did.”
Don’t get me wrong, pain is miserable and treatment needs to be better. But around 80% of opioid addictions start with prescriptions for people in genuine pain. What percentage of prescriptees that is, I don’t know. But it’s not a trivial issue, and it is a very difficult problem to solve.
It’s a term that originates with the left. Specifically, those who broke with the USSR over imperialist invasions, referring to those who did not. More broadly, it refers to the authoritarian left (as opposed to the anarchist left).
