The United Kingdom has banned opiate painkillers like Darvocet and Darvon, because of the high risk of overdose.
In the United States, the FDA has stopped short of banning the drugs, choosing instead to require a stronger warning label on all products containing propoxyphene.
After all, why shouldn't the big pharmaceutical companies continue to rake in the big bucks as long as there's a strong warning on the box? That fixes everything!
Way to go, FDA, you've shown your true colors once again.
