Um... what do drug overdoses have to do with the FDA?
Those drug abusers aren’t getting prescriptions for the drugs they overdose on. They’re getting those drugs from cartels who bring the drugs in on major corridors like the I-95 freeway or US 40 on the East Coast. No medical person advised them to take a drug in a manner it wasn’t prescribed for.
People who take opiates according to prescription aren’t going to overdose on them.
LOTS of BAD doctors have over prescribed them hooking people on a very addictive drug. It's in the newspapers, hundreds have been prosecuted an thousands were doing it.
