Do i make bracha on smelling vapor from herbs?

Question

There some vapors in electronic cigarettes made with natural herbs like chamomile (and other). So do i do brachot when smelling them?

Is there a common practice to smell natural things, is this kind of smell included?

Vapor from electronic cigarettes who do not burn the herbs, but vaporize them.

EDIT - Clarifying the question:

Well, i will clarify, there are many types of e-cigarretes, but one specific i think can be allowed, which is the one i'm asking, and i will explain it. This specifically e-cigarrete is for HERBS-ONLY (and not artificial liquids), so what they use inside the e-cigarrete: chamomile, Eucalyptus, green tea, Lavender, and many others, wherever herb the person decides to use. Second thing is that the herb IS NOT BURNED as the herb do not have directly contact with the heat. SO... It takes the smeel of the herb in the vaper, which makes sense to ask this question

Answer 1

Yes, it is like any other thing that you smell.

Smelling is the beginning (the most spiritual aspect) of eating. So it is important to identify the source of the smell, whether from trees (עץ), or herbs (עשב), or spices (בסם) or a mixture of any of the types (לשון מצ״ב ע״פ ס״ת), in order to make the appropriate blessing.

This is discussed in Sefer Shnei Luchot HaBrit and elsewhere.

It is worth noting that the blessing of scent is related to the concept of ascent (ריח), as contrasted with descent (ניחח) which is from the expression of the Sages for marrying someone below your economic status (ניחות דרגא).
