Opioid use and sleep apnoea
Opioid prescriptions in the USA have fallen over the past decade or so. But the numbers are still enormous. In 2020, US pharmacies filled more than 140 million prescriptions for opioids, enough to medicate 43% of the population. Some 10 million Americans are thought to misuse opioids, a category of drug that includes heroin, methadone, and morphine.
