New study shows e-cig vapor contains no more trace metals that typical air


The U.S. Food and Drug Administration (FDA) has often claimed that the vapor produced from e-cigs and vaping technology is enormously high in trace metals.  However, a new research study conducted by scientists from Tennessee’s Lincoln Memorial University (LMU) and Missouri’s William Carey University (WCU) seems to refute these previous claims almost entirely.

Furthermore, the researchers offer some rather interesting theories as to why and how agencies like the FDA can make such ridiculous claims in the first place.

The study was recently published on Frontiers in Physiology, and its co-authors claim to have successfully determined that e-cig vapor contains approximately the same level of trace metals as is commonly found in typical, everyday air.  They also agree with previous FDA assertions that the same vapor can sometimes consist of abnormally high levels of nicotine, depending on the brand of e-liquid ingested.

But unlike the FDA, the co-authors of this more recent study are also quick to point out that inhaling nicotine vapor is not necessarily unhealthy, especially when compared to the tar and toxin filled smoke derived from combustible cigarettes.

Trace metals percentages of e-cig vapor can be easily manipulated

So why do public health agencies like the FDA and the Centers for Disease Control and Prevention (CDC) consistently put forth government funded “research” claiming that e-cig vapor is filled with toxic metals?  According to these university scientists, the levels of trace metals found in e-cig vapor can vary greatly depending on a number of factors.

For example, most vaping devices heat the e-liquid to temperatures at or below 350 degrees Celsius.  Anything higher would result in a rather unpleasant vaping experience for the user.  Sure, it can be done.  But what’s the point?  The e-juice would taste terrible, and the vaper would experience a lung hit of epically dissatisfying proportions.

In comparison, cigarette smoke is generated at approximately 800 degrees Celsius.  So, one begins to wonder.

      • Do scientists conducting these “studies” for the FDA, the CDC, and other anti-vaping groups know the differences in heating temperatures used in vaping vs. smoking?
      • And if they do, do they even care?
      • Because if e-liquid is heated to the same excessive temperatures used in smoking tobacco, then the resulting scientific data collected would unwittingly or perhaps intentionally indicate that e-cig vapor is significantly higher in trace metals.

According to the LMU/WCU e-cig study, heating of vaping devices to temperatures of 800 degrees Celsius would cause the metals of the cartomizer, the coil, and the wick to burn away and be released into the air via the produced vapor.  Additionally, the individual filtration systems of the vaping devices as well as the tobacco cigarettes themselves also come into play.

It is discrepancies like these that can be a leading cause of so much junk science floating around on the Internet about the alleged dangers of vaping.  There are just too many individual factors that can be easily manipulated by the related researchers that will mistakenly or intentionally produce corrupted scientific conclusions.  For this reason, it’s probably best to read the fine print of the study before automatically accepting the advertised results.  Don’t believe everything that you read online.
