"Section one amends Public Health Law § 1399-aa to define an electronic
cigarette as a battery operated device that contains cartridges filled
with a combination of nicotine, flavor and chemicals that are turned
into vapor which is inhaled by the user."
See all the components you need there to make it illegal? It's got to be a battery operated device (is the sale of batteries illegal? nope) its also got to have a cartridge filled with 3 things namely nicotine, flavor and chemicals (so presumably unflavored nic cartridges are going to be ok) and finally its got to be both a battery powered "device" and contain all these other elements. A battery itelf isn't a "device" it's just a battery. Could be used in any number of devices none of which have cigarette applications.
A cartomizer isn't illegal because if it's delivered to you it could be powered not by a battery but via a passthrough so under this definition it fails to be illegal. Finally, it's got to have flavoring in it. If it doesn't, nope doesnt meet the definition. If you do away with the nic in it, nope, doesnt meet the legal definition. If they liquid is OUTSIDE the cartidge, again, doesn't meet the definition.
Are you selling an e-cigarette backwood brew? No sir, we don't even sell devices. I mean how are they going to handle that?
