What I can't understand is why would dealers be killing off their customers?

Granted, this is unlikely, but could it be a form of terrorism? I honestly don't know where heroin comes from, but if its an opiate, than the ME would be a source...

It's not intentional. Drug dealers ain't the smartest out there. There was an incident a while back (10+ years) where a guy killed himself while running a meth lab.

Turns out he'd failed chemistry twice in high school. SO WHY WAS THE IDJIT RUNNING A METH LAB?

It is because the Fentanyl/heroin combination is new and the people who produce and use it haven't yet found the proper non-lethal dosage. This is a bit of a Dawinian trial and error going on until the proper mix is found.
