I got my first E-mail from CASAA for an urgent call to action regarding a proposed ban to E-cig use wherever smoking is banned in Orange county, FL. In the instructions of what to say when calling or writing the city council members was this suggestion: 4. Detail how electronic cigarette use is easy to distinguish from actual smoking. Although some e-cigarettes resemble real cigarettes, many do not. It is easy to tell when someone lights a cigarette, from the smell of smoke. E-cigarette vapor is practically odorless, and generally any detectable odor is not unpleasant and smells nothing like smoke. Additionally, e-cigarette users can decide whether to release any vapor ("stealth vaping"). With so little evidence of use, enforcing indoor use bans on electronic cigarettes would be nearly impossible. Regarding the above comment highlighted in bold - I would like to know how one can vape and not release any vapor or "stealth vaping". It sounds like something I could use at times - I am using a tank system . Anyone know how this is done?
