If you are talking about the deeming regulations by the FDA, I'm not sure how long we vapers will have before the sale of vape gear becomes non-existant.
What happened back in 2007 when the FDA initiated their first ecig ban was US Customs put a hold on all vape related items. Most online vendors were forced out of business; there were no brick-and-mortar vape shops back then.
Unless you own a mechanical mod and an RBA, and can make your own coils and wicks, you'll be out of luck. If you are dependent to buy replacement coils for your tanks you'll be out of luck. The only ecig products that will be legal will be the cigalikes like Blu and Vuse.

e-liquid as we know it will be banned as "open container" nicotine products. So you better learn how to do-it-yourself (DIY) your own
e-liquid, and good luck finding a black market supplier of liquid nicotine.
