I'm just confused as to what's unacceptable. There is no legitimate second-hand smoke concern. Indeed, there's no smoke. It sounds like maybe there's an odor, so maybe that's something, though the odor is probably arbitrary. I've never noticed an odor from people using them around me. Is it the smoky look?

If the airlines would simply bring back smoking on planes this would not be an issue. :rolleyes:

Simply take your e-cig to the lave. No smoke alarm will go off. Puff away! ^

Airlines also should ban gum, chewing tobacco, perfume, dogs, cats, kids and old people (myself included). :rolleyes: OK, the kids can stay, but 5 rows away from me. Old people 3 rows away.:rolleyes:

Dogs and cats need to stay home or be put in the luggage compartment. Some people are allergic. If not, bring back peanuts!

The only part of this post that is serious - puff away in the lave. It is not smoke, only vapor. The allergic part is correct as well.

A coworker smokes ecigs in the office, i bought some for a family member - IME they appear completely odorless to neighbors (i am sure they still deliver plenty of harmful stuff to the smoker).

However from the airplane use standpoint i am somewhat concerned about vaporizing part - not the toxicity or smell under normal operating conditions but potential malfunction and either leak or fire...

I assume the main reason they are banned is because airlines don't want others that do no understand the technology to think that it is okay to light up regular cigarettes.

Otherwise, it's just a little scented water vapor that escapes. I have several friends that use it and in any kind of reasonably well ventilated area it's hard to tell they're even using them.

The smell would be a bit annoying on a plane (depending on the liquid) but otherwise causes no health or safety concerns for fellow passengers.

Its a battery and a heater. Less complicated then any of the electronics currently used such as ipad, laptop, phones, etc. If your worried about malfunction there is far more danger in those then an ecig.

We are probably getting OMNI, but do you have different information
Secondhand vapor from e-cigarettes contains nicotine but not other toxins: study

FDA: Second-hand smoke from e-cigarettes may be harmful to your health

Are e-cigarettes safe to use? New research shows metals found in vapor of electronic cigarettes

They emit odor, chemicals in the vapor, as well as second-hand smoke.

Smokers and drunk drivers share the same issues in that their actions selfishly affect innocent people. But, I digress.

There's nicotine in the vapor. Small amounts of nicotine are not dangerous. There is no smoke. That's just a scared-people myth.

As well as many other chemicals:

Someone made a little nutritional label for an organic Apple or something similarly mundane to show all the evil terrible things in it. Google it. Being scared of evil chemicals is so 1997. But you concede there's no smoke, right?

To get vaguely back on topic: I wouldn't mind UA changing this policy. I'd rather people do it out in the open than hogging the lav.

I don't ever use this product. I stick with the real deal - camel non filtered - 3 packs a day. :rolleyes::rolleyes:

Second hand smoke. There is NO smoke - only vapor, which the smoke detector does not detect in the Lave, therefore it is not smoke.

Are these prohibited on UA and almost all carriers? yes. Do people use them? yes.

Move to CA and enjoy the friendly skies. (smog in LAX and fog in SFO) :)

And more people using ecigs than real ones! At least here in LA.

This forum is known to the state of California to cause...

I'm extremely sensitive to cigarette smoke and I can tell when someone is smoking e-cigs before I see them doing it. Irritates my lungs. So I am relieved to hear that UA has banned them.

All major carries have banned them, for no reason. I guarantee you could not smell "vapor" if someone took a poof in the lave. I see you live in SFO - Good choice if you don't like cigarettes. I love SFO. My last visit, I had many options, give a bum $$ (several times, all over downtown), Prostitutes, Smog, etc.

At least in LAS you have all the same except we in LAS have timeshare salesmen. Trump. :p

My nephew started using e-cigs trying to quit smoking. I applaud his effort. But the kind he was using I found very annoying. Sounded like he was sucking on a bong all night with the gurgling sound it was making. Don' know if all are like that as is the only one I have ever been close to. Also found the smell unpleasant. I would not like to see these on planes.
