The wool touches the atomizer on most models. No big deal. The tempatures against wet wool are never high enough to melt the plasic, but many folks on many of these
threads question plasic by-products sort of leaching into the vapor. If you want a real kick in the teeth smoke analogs. These have true combustion of who-knows-what organic materials, producing 4000+ chemicals of which many are known to be carcinogenic. Decisions, decisions... Say you
vape for the next twenty years spending gobs of money in the process. After investing all that money, you don't even get the benefit of developing cancer! What a gyp!
