I have a smoke detecter and it hasn't gone off at all mate I don't think it could as it's odourless and not really smoke
Just so you know, a smoke detector works by way of a chamber having to fill and remain that way with super heated gases. These occur in all smoke layers. As the e-cig doesnt have any smoke a smoke detector SHOULD stay quiet.. (faulty ones can get a bit grumpy sometimes though!)
There we go, Darren's useless fact of the day! LOL
Happy Vaping!!
