This link is the main one you’ll want for some very good research:
http://www.e-cigarette-forum.com/forum/
These folks are the best source I’ve found. They know all about every model, liquid, brands, sites to watch out for, and the political side of the devices (FDA stuff).
So e-cigs are on the hit list, BUT they're making a loud noise about legalizing marijuana? Unbelievable.
