Electronic Cigarettes and Vaping

Welcome to our second show on the subject of e-cigs and vaping. Listen as we explore much talked about topics with this ever changing controversial subject.

This was a great show to showcase our ability to do a serious experiment, while also having serious fun 🙂

Here are some subjects we cover:

  • Are they healthier and safer than tobacco
  • Is there any danger of second hand inhalation
  • How much nicotine does it deliver
  • Are e-cigarettes on the rise for younger generations
  • Are they dangerous
  • Can they really help people quit smoking
  • Vaping hobbyists
  • What really is in e-juice

We even conducted a mad experiment! It wasn’t really mad, but it was crazy and Eli got attacked in the lab. If you don’t believe, just look below.

If you’re so inclined….here’s the data

As we promised, we said we’d share our results. Again, thanks to Aaron McAdie for all his amazing help on this and for providing explanations and images. So here we go…

The NIST reference file shows the IR (shorthand for FTIR) spectrum of propylene glycol. We can see that it has a high correlation with the spectra we collected from the various e-cig oils, although it is not a complete match, indicating that there are likely other compounds present in the e-cig oils. Ideally, we’d subtract the two peaks and take a close look at how they differ, but that would require either a propylene glycol standard, or a $5000+ spectral database and some fancy software, of which we have neither.

The IR search results file shows the spectrum we collected in red, compared to the reference spectrum for propargyl alcohol in blue. We can see how the online search tool found a high correlation between the spectra, but as we can see, there is also not a perfect match. Unfortunately propylene glycol did not come up in this search, even though it seems pretty likely that it is present given our prior knowledge and the similar spectral features.

The used comparison file shows the overlays of all the oils we tested. They are very similar overall, with the main differences lying in the 1500-1800 cm^-1 wavenumber range, which is where C=O bond vibrations are commonly observed, among other things.

The other used comparison file adds the spectrum of polyethylene glycol, which is the closest thing to propylene glycol we had in the lab.

The final file compares the spectra from the new and used cheeky cherry oil. They are overall extremely similar, with the only exception being the appearance of a small peak at ~1650 cm^-1 in the used oil.
