No. Of course not, why would you even ask such an embarrassingly inane question? Did you think it would make you look clever?
The vapour produced is neither steam nor water vapour.
It contains nicotine, diluent and flavouring.
These products are often sourced from outside the EU and are not of medical grade. The flavouring is often made with food grade products, safe for digestion but not designed for inhalation. The products still cause lung damage.
Diluent is a mixture of propylene glycol & vegetable glycerine (again food grade). The ratio can be altered to produce differing levels of vapour vs throat hit for those that prefer a more cigarette type feel, however the stickier your diluent mixture the quicker you will burn out your coils.
I've mixed an awful lot of vaping liquid, so I know what goes into it. You very clearly do not. Tell me, if you think it's just steam, why are people so addicted to it @m340? Perhaps you ought to watch Big Vape on Netflix to see some of the long term consequences of your so called 'steam'.
Do you get a sore brain from all the thinking?
