Testing done by ANALYZE Inc, a premier independent consulting laboratory has determined that the vapor produced from the electronic cigarettes they tested do not contain any detectable levels of carcinogenic TSNAs. They tested electronic cigarettes marketed by NJoy and found that “there is no evidence that carcinogenic TSNAs are present in the aerosol”.

This is contrary to the FDA study which held a press release in mid 2009 to announce they had found carcinogens present in electronic cigarettes. So why this discrepancy? Well it appears the FDA testing was done on the liquid and not the vapor, which is what consumers inhale. As Jack Leadbeater, CEO of NJOY says, “In July the FDA released study information about the constituents of our electronic cigarettes that may have inadvertently misled the media and consumers about their health risks…. the FDA analysis evaluated only the contents of the cartridges used with our products, and not the constituents of the aerosol or vapor to which users are actually exposed or the potential health risk, if any, that may be posed by that exposure.”

  1. The paper you link to explicitly says that there was no TSNA in the liquid tested in first place.
    And that when TSNA were added to the liquid these indeed transferred to the aerosol.
    So, it’s not a general refusal of the FDA claims, but a proof that nJoy liquids as of 2009 did not contain TNSA. Which serves the purpose as the study was commissioned by nJoy.
    If you don’t want TNSA in your vape, it sounds like you need to make sure they are not present in your liquid in first place.
    So not too reliable information, I am afraid.

    From the study:

    No target TSNA compounds were detected in any of the analyzed sample solutions by the liquid
    extraction method. No peaks were detected at the expected analyte retention times in the
    chromatograms produced by the sample liquid extracts; representative chromatograms are
    included in the Liquid Extraction Appendix. All limits of detection are listed in the Summary
    and in text Table IV.

    1. The point was that the FDA was not forthcoming with their testing, but rather with their predetermined conclusion.

      There has never been a study showing a significant level of TSNA in the vapor, which is what needs to be tested since it is what is inhaled. The more nicotine you have the more TSNA. But any level is not necessarily dangerous.

  2. I read the study and after some poking around on the internet, I have not been able to find a record of a “Professor Ben Thomas” anywhere. Not on ratemyprofessor.com, not on the University of Texas Health Science Center at Houston faculty directory, no mention of him on google, nothing. Could you provide a record to show that this guy even exists? I smoke an e-cig and as much as I want this study to be valid, how can I know that if I cant even find the name of the guy who did it? Surely there would be SOME mention of this loftily qualified man’s name on SOME website other than on your PDF document.
