Anything with seaweed as an ingredient has to have a warning label:
Pure seaweed product, dried sea vegetables, nori sheets, roasted nori snacks, even furikake.
Stickers added to the product, signs hung on the shelf next to the product,
Even signs that you might want to reconsider entering the building since it contains items that have been shown to cause cancer.
Nowhere is safe! You can even get cancer at the happiest place on Earth!
Basically all areas, living spaces, outdoor areas, common areas in California causes cancer.
The only logical conclusion is that California causes cancer.
