@vaalboy once triggered a smoke alarm in a hotel. There are 2 different types of smoke detectors on the market: (1) Detects carbon particles and it would be very difficult for an ordinary vape device to trigger this type (except if there is a lot of gunk on coil and/or you start burning the wicking material), and (2) Optical topology which triggers when 2 closely opposing light emitter and light detector are obstructed - this type will be triggered with enough vapor.
