I have zero sympathy for big pharmaceutical distributors that made billions off of opiod sales. However, this is just the DEA trying to shirk its own responsibility.

If prescribers are overprescribing opioids and/or pharmacies are diverting the prescriptions, the DEA should be the ones policing that. If a company is filling valid prescriptions which were written by a prescriber with an active DEA license and sent to a pharmacy with an active DEA license then they should not be liable. These companies are not providers or pharmacists. For all they know, the prescriptions are legitimate even if they are suspicious. And if they're not legitimate, it needs to be the DEA that detects it and takes action.

But what if they're not staffed for it? The answer is that they are and have been since the late 80's. But they're focusing most of their efforts on stupid things like cracking down on marijuana possession and busting small time dealers.
