I don't do benzos and I know next to nothing about drxanax or quantik but if quantik is indeed located in Canada then this is only the beginning.
Even if DrX doesn't know quantik or is Stratton or whatever the fuck the history is, what DrX and his crew does know is the game.
They know the likely sources, how said source is likely to be acquired, friendly places to get quality binding agents, postage/packaging/shipping methods.
I'm not sure if the US mail cover program starts at customs or not but it shouldn't just be the people who ordered from him in the past month that should be sketched out. They in all likelihood will easily paint his pipeline.
Throw in the theory that some ppl believe DrX to be Stratton who used to work for quantik right? That would mean not only does he know the general ins and outs, he knows the specifics of quantiks business to an extent and they may know each other by real names.
This whole situation is bad for everyone. Now that they've had a major bust they're likely to have a hard on for it now and there's safety in numbers quantik.
Now he's more likely to be a sole target and they have more ammunition.
I wouldn't touch shit from Canada now if you're in the US. I could just be paranoid but I can see far reaching ramifications of this bust.
As polite as our neighbors to the north may be, you can be damn sure they've bought the same damn sorting machines the US uses.
Now, how useful is that information to LE? His downstream bulk buyers might be good targets that will keep all the task forces busy for a while. I would think personal use buyers would be more trouble then they're worth.
Upstream leads to China so anything inbound will get snagged until that supplier changes their modus operandi. They'll definitely scrub some databases and see if something juicy pops up.
