It was never about health. It was about power---New York City Extends Smoking Ban To E-Cigarettes

Quite simply, rich, thin, rich, morons. 
Did I mention "rich"?
They don't understand E-cigarettes and they don't like the look.
The "look" is important.
Doncha tink?
Plus, banning stuff we don't like is fun!

New York City Extends Smoking Ban To E-Cigarettes : The Two-Way : NPR:
"New York's City Council has approved extending the city's strict smoking ban to include electronic cigarettes, which emit a vapor.
The measure was pushed by outgoing Mayor Michael Bloomberg and backed by public health advocates in the city.
It comes just weeks after New York became the first major city to raise the age for buying tobacco to 21.
Earlier this month, New York City Health Commissioner Thomas Farley said that "more research is needed on electronic cigarettes," but that "waiting to act could jeopardize the progress we have made over the last few years."
Reuters describes e-cigarettes as "slim, reusable metal tubes that contain nicotine-laced liquid in a variety of exotic flavors such as bubble gum and bacon.""
