Largely unregulated China? I swear this is getting ridiculous. Your home is filled with chinese stuff. Everyone you know uses chinese stuff. Get off the 'unregulated' bit. e-liquid is highly regulated in China.
No need to swear... As a retailer, my company has been selling Chinese products for nearly a decade. So you don't need to tell me that my home is filled with stuff made from China.... I know. But for you to make such a bold statement that "XXX is highly regulated in China" is beyond me. Saying that is no different from saying "the FDA purely has my health in mind."
Let's get real. We can hope that the e-liquid manufacturers, or for that matter, any manufacturer, will uphold and do the right thing. I can hope that my burgers from Jack in The Box is not tainted.... or I can hope my Tylenol does not contain cyanide, I can hope that Ford will not "let the people burn" if the Pinto was found to have a defective gas tank, I can hope that the pet food I buy is safe for my pets.... so on and so forth.
