Question about Vapor Suspending in Air

[flintlock62]

I have not heard about whether the vapor from e-cigs remains in the air, or does it drop to ground level as the vapor cools. I know that the particulates from cigarette smoke does float around for some time. I ask this because of the bans some cities have in place, or are considering concerning e-cigs. If the vapor (water droplets) falls to the ground as it cools, then there should be no danger what so ever to by-standers, right?

There is no danger to bystanders from what I have read on the analysis of the vapor expelled.

What may have been true in the blu/mistic days of last week is probably no longer true. Those little guys produced so little vapor, that I would think the vast majority of the nicotine was contained in the person vaping. These giant steam machines we're creating are probably a different story however. Expelled water vapor is absorbed in the air up to the point of saturation (100% humidity) and only then does it precipitate. Since the nicotine is bonding with the vapor, it stays suspended in the humidity of the air. Whether or not it is harmful of course, depends on the quanity of vapor, and the size of the room. Outdoors, probably not an issue. In a small room with several vapers puffing on big rigs? I wouldn't want my children standing around too often. Blowing it in non vaping peoples faces? DEFINITELY not cool.

Let's say, and this is purely hypothetical, that you're using 24mg nicquid. One mL is approximately 20 drops. One drop will yield 3 puffs. So, you take a puff. That puff contains ~.4mg of nicotine. You absorb, let's say, 50%. So, you're exhaling .2mg of nicotine. The toxicity of nicotine for an average human is 60mg.

I see no way that .2mg of nicotine will harm anyone. Hell, nicotine is an insecticide and when I've blown a puff at a mosquito it's had no effect. I still get bit.

Nicotine is in tomatoes and eggplant to name just 2 items.

And darn it, I guess I can't use it to repel mosquito's. Foiled again!

I agree that caution around children and the elderly and otherwise infirm (not that children and elderly ARE infirm) is probably both wise and considerate,,,,

I just find it ludicrous that ecigs can be banned and cigarettes allowed in some places,,,,,I think the risk is so low as to be ludicrous, and I'd be far more concerned about someone smoking 5 feet from me than someone vaping ONE FOOT from me,,,,,,

but again, courtesy is paramount.

in public places, I'm one of those strange ones who either go off and find a place without many people,,,,,,or vape in a smoking section. I won't vape standing in line at Disney world with 500 other people,,,,,if I can reach out and touch someone, I won't vape unless I'm in the smoking section,,,,,,,,,,yeah, I'm strange. I just don't get into upsetting people.

Having said that,,,,,,vaping in smoking sections sucks ..... They stink. I don't make a big deal out of it, because God knows, I used to smoke too,,,,,,but I really hate the smell now. OTOH, I've had the opportunity to educate many smokers about other possibilities, I've been asked many times "what are you smoking? where can I get one?" etc,,,,,,

Yes, the general public needs educating too,,,,,I'll leave that to others,,,,,,I'd rather educate people for whom this could save lives.

 

[CommaHolly]

Oh, I forgot LOL,,,,,,

I've noticed that the vapor can "hang around" in the air for several minutes,,,,,,,especially in a place the air doesn't move,,,,,,like my car without the a/c or the window open. but I've never seen it "drop" to the floor,,,,,,,,the particles are probably too small to see after a while to know for sure.

 

[flintlock62]

You won't SEE water droplets drop to the floor.

I know that steam will stay in the atmosphere until saturation is reached, but I'm not too sure that vape is heated enough and the size of the droplets created from vaping are small enough to stay suspended for too long. Maybe I should have been more explicit in my OP.
The size of the droplets from vaping, as opposed to steam should (or could) make a difference.

I was wondering about this as well. The worst thing about quitting smoking is now being anywhere near someone smoking. I live in Nevada and like to gamble at least twice a year now Im thinking that will not be possible since the casinos stink to high Heaven! There is a smokeless casino but its over 100 miles away I just cant imagine putting myself around something that makes me want to throw up. Good topic by the way Have a great day fellow Vapers!

Didn't Nevada overturn a ban on smoking in bars and casinos?

Anyway, water vapor dissipates much quicker than tobacco smoke (I'd say within 10-15 seconds depending on the size of the cloud). It does generally rise. Most people don't even notice it though. That's how fleeting it is. It's even less noticeable if you are outside or in a very bright room. Most smoking bans don't apply to e-cigs as studies have proven what we already knew from the start: "secondhand vapor" is 100% harmless. Hell, it's mostly odorless too.

 

[FirinBlanks]

They say that nicotine in the quantities that we have is no less harmful than caffeine however pregnant women are told not to have caffeine so IMHO consideration around pregnant women, the elderly and the young should be practiced.

 

[Harplayr]

Here's a good study on "Second Hand Vapor". It shows it to basically be harmless.

For those that are arguing that "some" nic will be exhaled, while probably true, think about the volume of air in a room VS the volume of air in your mouth. As the studdy shows, a small room full of chain vapors causes just a tiny ammount of stuff in the air.

Take a drinking glass, turn it upside down and exhale some vapor in it. Place the glass on a flat surface/table. See how long it stays in the air. Afterward, examine the internal surface of the glass and the surface on which you placed the glass.

The vapor takes a very long time to disapate or settle. Surprisingly long. What it means? I don't know.

Thanks for that chart. By the looks of it, it's MUCH more harmful to live in Los Angles and breathing polluted air from car exhaust and factories.

It probably means that if you blow vapor into your girlfriend's mouth while kissing, she'll get a mouthfull of vapor.

More seriously when I smoked in my car the smoke and stench stayed a LONG time and coated the glass and windshield with a film. Now that I vape in my car (windows closed) the air is clean, no residule smell and no film on the windshield.

But if you want to know what is in the air after vaping in a closed room, the study I posted is a good starter.
