The problem with all these "electronic devices", is that they are advertised, (marketed), as being a drug delivery device. They are also advertised as being "Safe" or "Safer", which requires proof beyond assumption of "More is bad, so less is safe or safer." (Though that may be true, it is not medically proven or documented, for these devices.)
In essence... the device is not "Safer", as it can explode, catch fire, melt, cause acid burns, and shock you. (Cigarettes can't even burn you, until you ignite them. Just for one far-fetched argument of the "Device being safer". Not the fluids.)
The fluids are being marketed with the devices, and the fluids are also being marked as safer... but can you tell me what is in there? No, because there are no labels. You could be vaping tea, or cat urine, or monkey poo. I hear cats are popular in China.
Having the name... "xxx Cigarette", "xxx Cig", "Cig xxx", "Cigarette xxx", "Smoke xxx", "xxx Smoke", or imagery and instructions that indicate the device is to be used for lung-consumption, makes the devices a non-food item. (Thus food-safe holds no water. Since the devices/liquids are not being sold to eat.)
This is where everyone is just wrong. (The marketers not the customers.)
If the device said... "Permanent Marker", and advertised as a writing tool... that would be FDA approved, for use as directed. (Does not make it safe, only safe for writing, as directed.)
If that same device said... "Portable High-Stick", and marketed as an entertainment tool... the FDA would ban that item, but that item could be re-marketed as a "Permanent Marker", and the FDA would leave it alone. It could exist on the shelf, right next to the "Permanent Marker", and it would get pulled off the shelves, because of the marketing.
(Disclaimer: Permanent markers should only be used as directed.)
It is the manufactures responsibility to apply for FDA approval, if they want to sell in the united-states, marketed as a nicotine delivery device. The FDA does not just pick items, and say... Ok, we have approved you, here is your stamp. The company has to apply for a review of the device, application, and submit proof of all claims.
In the laws eyes... it is the person who sold the device, without checking if the device was legal to use in that respect, who is breaking the law. The company is not responsible for how a seller has marketed the devices. For all the manufacture knows or cares... you ordered this stuff to kill rats, not to consume.
Don't send money to anyone claiming to be lobbying for approval. There is nothing that can be done about a banning. It has already been proven that the devices are illegally marketed, and making false claims. Unless you are lobbying for them to close their eyes, so the manufactures can continue to sell you unlabeled chemicals of unknown composition, and unregulated, selling possibly 20mg in this 20mg bottle, but oops, we forgot to add water... you got 2000mg in this bottle! Who cares, it is for the Americans... They can sue that e-seller, and get nothing. They paid for unregulated sales.
Find the manufactures, and demand it. Within a year, you will not be able to find any parts, and the manufactures will move on to MP3-players or the next novelty.
Better yet... buy 100,000 an market them as personal mouth-fresheners. Let the liquid guys fight the law. There are more people with bad breath, than there are smokers, who are willing to risk trying a device that sprays mystery chemicals into their lungs.
