"In late June, Reston became the first town in Washington to address the use of e-cigarettes when the Reston Association board of directors voted unanimously to ban them from public spaces." (

My Vapez Lounge in Herndon is 100% vape... starter kits up to Caravelas (until the latter sold out, anyway). They'll be opening a second shop in October ... Falls Church, I think? This is a solid local resource, one of the few local places I've found to sample juice before buying, for example.
Smoke Time and Capital Cigar and Tobacco, both in Annandale, have some vape stuff in addition to tobacco products, but most of it is basic. Still, good to have some brick-and-mortar options nearby. Imho Smoke Time is the better of the two.
