Second Hand Vapor

For the user, it’s obvious that vaping is a great alternative to smoking. Many of us, including myself, now prefer vaping to smoking entirely. I really enjoy all the different flavor options and being able to vape a single hit or two without dedicating 5-10 minutes to go have a cigarette.

Now what about what you exhale when vaping? We already know what’s in the e-juice, but what exactly is coming out of our lungs into the air to potentially bother those around us?

The most recent study I know of is conducted by clearstream working closely with utah vapers. The study has completed and is now in the process of full doctoral review so the summary is no longer published at that page. The short version is that second hand vapor contains no harmful chemicals and no nicotine. Really the only possible irritants that I can think of are the trace amounts of flavor.

Here is an excerpt of what used to be there:

In December 2011, the Utah Vapers began working closely with FlavourArt from Milan Italy to research the current studies on electronic cigarettes. What we found is a lack of evidence to support the belief we all had in that there was no harm to bystanders in exhaled vapor (second-hand vapor). After months of coordination, Clearstream Air was announced to the world electronic cigarette community on 22 March 2012 – also known as World Vaping Day.

Simply put, the Clearstream Air project is a comparative evaluation between tobacco and electronic cigarettes and hoped to draw a positive conclusion about the lack of harm with electronic cigarette usage. The study focused on the release of airborne contaminants in closed room environment to determine if there are any contaminants and if so, at what levels.

The following substances were measured for in the exhaled smoke and vapor.

  • Carbon monoxide CO
  • Nitrogen oxides NOx
  • Acrolein
  • Polycyclic Aromatic Hydrocarbons PAHs
  • Volatile Organic Compounds VOC
  • Total Organic Carbon TOC
  • Nicotine
  • Glycerine and propylene glycol (components of the electronic cigarettes fluids)


Study Results

As the study has been completed and a professional doctoral review completed, I’m proud to announce that the results are better than we could have anticipated. In short, there is NO harm found in exhaled vapor from electronic cigarettes. The most exciting results I found is that testing did not detect any nicotine in the exhaled vapor. Now, you may ask why I find this exciting. Well, my excitement is on two levels. 1) This means that the human lung absorbs most if not all of the nicotine which has long been questioned within the global electronic cigarette community; and 2) This also means no nicotine was detected in the ‘second-hand vapor’. All other substances measured for electronic cigarettes were FAR below allowable levels for human inhalation according to the FDA. In fact, the levels were so low that it proves it is more hazardous to your health to breath the air in any major downtown metropolitan city during heightened times of driving.

I invite you to review the study yourself and draw your own conclusions. If you are in the medical or scientific fields, please take the invitation to review the report in detail and let me know if you draw a different conclusion. If you prefer to wait for the full doctoral paper, we anticipate the full peer reviewed release of this paper to occur near the end of July 2012.

    Thanks for the information. I started vaping a month ago and really enjoy it but wondered what I am exhaling into the air. I’m still afraid to vape in public places because I don’t think people will be willing to accept it.

    Good to know. I gave up cigarettes for vaping about 2 months ago, and I am already feeling MUCH better….I’ve dropped the nicotine content to 18mg, and the chronic “smokers cough” I’ve had for years is completely GONE! As for the toxicity of second hand vapor, I was concerned. We have our 6 yr old grandson living with us (have NEVER smoked cigarettes in the house), and we have our 18 month old grandbaby visiting for the Christmas holidays. I am VERY much relieved that there is finally a report that clears second had vapors. It’s not like there is much floating around the room anyway, but still…. Thanks for this information!

      I quit smoking cold turkey in Jan 2000. My husband has been off cigarettes for about one month now because he switched to the vapor Ecigs. I am THRILLED about that. However. I positively, definitely, undoubtedly notice a difference in the air quality of our home. I get a sore throat from it. We are shut up in the house right now because of winter and I have a sore throat every day now. The problem is my husband switched to a stronger Ecig. They are making stronger than ever now. The milder ones didn’t bother me. He agreed to vape on our enclosed porch now instead of all over the house. Eventually he will decrease the dosage and can vape in the house then eventually be free of all that. The Ecigs are a WONDERFUL help to get off cigs. Some people get real angry at you when you touch their addiction but I’m only telling the truth. In the summertime I don’t think it would be a problem for me with fans on and doors and windows opened, but right now it definitely is.

    I am glad to hear this. I am going to be printing this out. I vape zero nic and I do it to relieve stress. I use it at the community college and a friend of mine has had personell at the college call the schools public safety on him. THey keep telling him he is “smoking” and thus it is illegal to do in the building. I was not told to stop vaping though. Now I can show the school that it is NOT a dangerous thing and better.
    Thank you very much.

    I have been reading various studies all morning, started vaping about 3 wks ago and have already noticed a huge diff in my asthma, AND headaches (recent brain surgery). I am using it as a path to be off nicotine eventually, but right now, I am enjoying it! The flavors are awesome! (Red bull or raspberry are so far my fav’s)

    The entire study should be available by now. Could you please tell us where to find it?

  7. That’s actually pretty interested. You see a lot of vape rooms around town. Wonder if this will be in part of consideration when it comes to the legislature. Second hand Air quality with the E-Liquids

    What about the vapor that does not get inhaled by the vapor user. I have seen plenty of vape users and not all of the vapor is inhaled. I would expect that vapor to still contain nicotine.
