Health and heating coil material?

[Etsu]

Hi everyone,

I found that article about metal concentrations in e-cigs’ liquid, due to the metallic heating coils, and I was wondering if it isn’t the same for our lovely vapes, let’s say the Fury 2 or the mighty for exemple (I use these two daily).

https://ehp.niehs.nih.gov/ehp2175/

Here is their statement:
« Our findings indicate that e-cigarettes are a potential source of exposure to toxic metals (Cr, Ni, and Pb), and to metals that are toxic when inhaled (Mn and Zn). Markedly higher concentrations in the aerosol and tank samples versus the dispenser demonstrate that coil contact induced e-liquid contamination »

I know the herb in vapes is not in direct contact with the heating coil, but we inhale directly the air passing through that coil that heats the herb. Being totally ignorant about that technology, I apologize if it is a dumb thought.

Have a nice Sunday!

There are some materials that handle high temps better than others. Glowing red hot metal is never a good thing though. I have TUBOx which has 316L coils which dont need to be redhot in order to vaporize. Also there is a temp control making sure of that ,unlike with some unregulated devices where you have to rely on your jedi sense. . I am a real flavor snob and the tubo tastes the best of all non-all glass vaporizers i've tried ,but i will always be able to make a difference to an all glass, even blindfolded though )..

I feel comparing 'e-cigs' to most herb vapes is truly not a worthy comparison.

Most flower vapes vape the herb is in some kind of oven/crucible where it is heated with radiant/conduction heat or convection with hot air pulling through the load. These vapes also often include an isolated airpath from all electronics and can cost over $300 with the intention of being used for several years. Quite a bit different than the 'e-cig technology' imo.

One cannot say any vape is completely safe without scientific testing. Until then...vape 'em if you got 'em

so, in your opinion, the problem would not really be the metal coil, but non appropiate airpaths of e-cigs? I believe metal coils can be a problem if not of a correct alloy, but I think you make a valid point and the study only seems to take into account the metal of the coil and not the metal of the electronics and unit's body, etc. A similar study with portable dry herb vapes would be awsome!
