I wonder where all the color in the highly colored
ejuice goes? if not in the vapor you exhale it all stays in your lungs?
Some may be in the vapor, but the coloring is so diluted by the volume of vapor produced you won't see it. I would imagine most is exhaled. Back in the
ecig dinosaur days some daredevil type folk wanted to attempt to obtain colored vapor but it didn't work out real well ( no color, lots of lung irritation). Before I took my last sabbatical from ECF, the community was very anti-coloring - Lorann's grape was taboo, for instance, and pressure was brought to draw on flavoring companies to remove colors altogether. Not sure what happened on that.
