No nicotine? E-cigarettes work by producing vaporized nicotine for you to inhale. You claim earlier in a post you've gone for 24mg Marlboro liquid. What do you think the 24mg refers to? I'll let you figure it out yourself.
There's a reason health authorities in many countries have not approved them and some of them have outright banned them. Unlike the approved cessation methods like inhalers or gums or patches whose manufacturing and dosage follow certain provisions and controls, the e-cigs have none of that.
Having some passengers unsettled and some others thinking it's ok and lighting up real cigarettes is a situation airlines would want to avoid. Besides, (regardless of what the e-cigarette marketeers claim) until someone can prove that part of the nicotine vapours inhaled will not be exhaled (for others next to you to breathe in turn), I'm not convinced that passive smoking can be ruled out. The rule makes sense.
