hey its all good some times its good to laugh at ourselves i know i needed a good one today it has already been crappy so thanks guys love peace & chicken greese..
lmao.,.

Edit..vape the thing not smoke haha....
With that said I will be honest and say I dont even vape indoors in public, idk if i ever will either. PPL will still have an issue with it, especially in a restaurant. Just because you can do something doesn't mean its a good idea. Im in Canada and ppl complain bad so the last thing i want is negative feedback on the PV. To each there own though. At least don't be disrespectful with it, make ppl curious about it and not peeved off. Cheers
The Lungs do a Poor job of Absorbing Water Vapor. Has to do with the Size of the Water Droplets and the Permeability of the Lungs.
And that is Actually a Very Good Thing. Otherwise you would Drown if you went Outside on a Foggy Day.
Your getting your Nicotine from your Mouth and Throat if you Inhale or Not.

BTW mwplefty – I can’t think of a Better way to get Indoor vaping Bans going than Blowing Giant Clouds of Vapor in a Restaurant.
Thanks.

Why would any grown-up act like this? It's a public place, people are eating, good grief.
Your rights end where the other guys begin.
I hate when I inhale, and vapor goes down my throat, into my lungs.
I bet you looked silly and annoying causing this scene you describe lool.

This. Our lungs are made to operate with gasses (air). Smoke is gasses with tiny little particulate matter (that builds up in the cilia; this is why we coughed as smokers). We have to inhale the smoke to get much nicotine.
Vaping is liquid vapor, even though we can breath it down along with the air (part of the smoking ritual/habit). Our mouth/nasal/mucus membranes are what absorbs the nicotine from liquid.
Make your own study! Exhale through your nose, you give it more area to absorb nicotine. When I started vaping, I breathed it down, because as a smoker, that was what you did. Eventually I noticed that I hardly inhale at all anymore. I'm doing it for the flavor and the nic, and I don't need to inhale it for either.
Vapers that want massive throat hit are the exception, of course.
I was reading on another thread, about the Lexington meet, and some Dr. actually stated that nicotine is very readily absorbed from the lungs. If things were not so readily absorbed by the lungs, perhaps all those asthmatics who pretested this stuff for us should just throw those rescue inhalers away. The medication is suspended and won't be absorbed anyway.
I will be sure to tell the ICU doctors I work with as well that someone on some forum said stuff isn't absorbed by the lungs so we shouldn't be giving any meds that way. I am sure they will ask you for your study.
PLEASE, if you are a mouth breather nose breather or whatever, don't be obnoxious and make clouds when out in a public restaurant. Whether you inhale or not. There, I fixed it, feel better?

Here is a study I found on ecigs:

And another one about inhalers that seems to support your claim about less nicotine is absorbed in the lungs than in the throat with inhalers, though it doesn't mention ecigs.

Abstract
Nicotine inhaled in smoke is the most rapid form of delivery of the drug. With smoking, arterial boli and high venous blood nicotine concentrations are produced within seconds and minutes, respectively. The potency of nicotine as the primary reinforcement in tobacco addiction is attributed to this rapid rate of delivery. By design, nicotine treatments reduce the rate and extent of drug delivery for weaning from nicotine during smoking cessation. Theoretically, they prevent relapse by reducing withdrawal and craving associated with the abrupt cessation of cigarettes. The nicotine inhaler treats the complexity of smoking through weaning both from the drug and from the sensory/ritual components associated with smoking. The inhaler is 'puffed' but not lit and there is considerable 'puffing' required to achieve slower rising and lower nicotine concentrations. These factors allow it to be used as a nicotine reduction treatment. One inhaler contains 10 mg of nicotine (and 1 mg of menthol) of which 4 mg of nicotine can be extracted and 2mg are systemically available. Shallow or deep 'puffing' results in similar nicotine absorption. Nicotine is delivered mainly to the oral cavity, throat and upper respiratory tract with a minor fraction reaching the lungs. This was confirmed with positron emission tomography and by assessment of arterial concentrations. A single inhaler can be used for one 20-minute period of continuous puffing or periodic use of up to 400 puffs per inhaler. With controlled puffing in laboratory testing, venous plasma nicotine concentrations from a single inhaler puffed 80 times over 20 minutes averaged 8.1 microg/L at 30 minutes. Lower concentrations of 6.4 to 6.9 microg/L have been reported for self-administration under clinical conditions. The time to peak plasma concentrations varies but is always significantly longer than with cigarette delivery. Estimates of nicotine intake from cotinine concentrations were higher than expected (60 to 70% of baseline smoking concentrations). This elevation may be due to the swallowing of nicotine and subsequent first-pass biotransformation to cotinine. In general, venous blood nicotine concentrations are considerably lower than with smoking and are within the range observed for other nicotine reduction therapies. Efficacy trials show consistent superiority of the inhaler over placebo. Despite the 'cigarette-like' appearance of the inhaler and the associated sensory/ritual elements, little treatment dependence or abuse has been reported. This is attributed to the slow rise time and low nicotine blood concentrations. The inhaler is a valuable addition to treatment of tobacco dependence and can be used alone or with other treatments.

It's normal to inhale. If I'm having a bad day I will inhale the e-cig straight into my lungs without taking puffs.
Inhaling or not STOP MAKING A HUGE OBNOXIOUS SCENE out of vaping. It exacerbates the misgivings and misinformation people have about what we're doing. You don't have to hide or be stealth all the time but for pete's sake stop making a huge production of it, it's rude to others and makes vaping as bad as smoking in people's minds.
my simple philosophy...
clouds of vapor = at home or in my car
hold it in the lungs for an extra second so only a little vapor exhaled = anywhere in public
it goes back to the statement made earlier about CAN vs SHOULD. you CAN talk smack to a cop giving you a ticket... doesnt mean you SHOULD.
most vapers here are well known with the stigmas that come with smoking, we vape as a healthy and positive alternative. we want to convey that message and not just a "haha i found a way to smoke inside legally"
and just because you have to be over 18 to vape doesnt mean you have to act like an adult!
