I also think it's significant that the liquid is vaporized. Certainly it's quite different to smoke tobacco than to eat it.

Vaporization is a physical state change, whereas combustion (and digestion) is a chemical change.

As tristanj pointed out elsewhere in the thread, studies have shown that chemical changes are happening. See the study tristanj linked, http://pubs.acs.org/doi/abs/10.1021/acs.est.6b01741
