One tired old statement often spouted by the naysayers is that there have not been enough studies done on e-cigarettes to know if they are harmful.
What IS HARMFUL are these type of statements, they are simply not true (see link below) and could prevent many smokers from switching to this scientifically proven safer alternative to cigarettes.
We feel it is important to note that claims made about e-cigarettes being “safe” can be misleading and therefore should be taken to mean “safer than cigarettes”. Anything inhaled other than pure fresh air surely can not be considered 100% safe.
Ecigs are safeR because they produce vapour not smoke. Boiling water produces vapour – fires produce smoke.
