The only part of the ordinance that I can find that relates to ecigs is this :
Section 13-139. Electronic Smoking Devices.
An establishment that has as a primary source of business the sale, distribution, and/or on premise use of
electronic smoking devices and related products shall not allow or employ persons under the age of eighteen
(18) years within the establishment. This shall include, but not be limited to, vapor lounges, vapor bars, vapor
salons, and vapor stores. Such establishments shall display signage prominently at entrances stating that
persons under the age of eighteen (18) years are prohibited within the establishment.
