Looking at formaldehyde first, it seems the higher the PG content, the more formaldehyde will be released. In the case of 50PG/50VG ratio and 100% PG, it seems the higher the voltage being outputted by your device, the higher the levels of formaldehyde will be released. For 100% VG, no formaldehyde is present. With acetaldehyde and acetone however is present in all three groups. With acetaldehyde 100% VG has the lowest level, then 50/50 ratio, than 100% PG. With acetone, 100% VG is still the lowest followed by 50/50 ratio and 100% PG similar to acetaldehyde; however unlike acetaldehyde it seems more acetone is released with the 50/50 ratio when voltage is increased, more than the 100% PG actually.

The most important results were as follows:

This story demonstrates how low the integrity of research in the tobacco control movement has sunk. In today's tobacco control movement, we can draw conclusions before even conducting research because we are apparently capable of predicting the results of our experiments before they are carried out.
