I thought that sounded like that number made about zero sense, and I found that the “80%” figure you mentioned has been repeated all over the place and it’s incredibly false. At one point in time, at one point, the United States had 80% of world’s sales for oxycodone. 99% for hydrocodone (every other country uses different stuff like classic morphine). Careful with statistic facts and numbers out there, I tend to remind myself constantly.
