SDA might be a mixup, I'm getting SAD in another scan. It was mentioned earlier by Vergo after his appearance. "I was in Dresrossa and heard a SAD tanker was heading out, so I caught a ride." I don't remember the raws for that one or this recent chapter.

Given the "tanker" and production and CC's creations. I'd bet it's some kind of drug. It's produced in that area and shipped out by tanker to other places. From the comments of upsetting the whole new world.. maybe psychotropic drugs? Or a derived steroid/growth agent from CC's experiments on children. Whatever it is, it's been in production, distributed, and probably already used in places.

-Edit-- Right after posting I got to wondering, there's a steroid theme going since fishman island. Or if it's drugs, Law's gonna spike a shipment of sweets and drive Big Mom's crew insane.
