My understanding is that nothing has changed. They're just applying the law to an existing classification of Nicotine as a poison and enforcing it. It was already illegal to sell e-liquid before, they just clarified that it was illegal.
Incidentally this is exactly the same as the situation in Australia where it is illegal to sell or distribute nicotine products. You can buy zero nicotine liquid locally, but they're not stopping users from ordering e-liquid abroad for personal use. If I buy it on the Internet for my own use that's ok. If and give some to a friend for free - that's distribution and becomes illegal.
If they ban e-liquid sales locally I can live with that, as long as they don't prohibit overseas purchases for personal use!
