Consequently we must make judgements according to the toxicology of the vapour. Irrespective of alarmist commentaries, experiments to the toxicology of your vapour inform us that, when propylene glycol can be an irritant and some toxins are present in measurable portions, the concentrations are in reality quite lower.four Some evaluations have bizarrely concluded that we have no idea no matter if e-cigarette use is safer than smoking,5 disregarding The point that the vapour is made up of nothing at all such as concentrations of carcinogens and toxins as cigarette smoke.6,7 The truth is, toxin concentrations are Nearly all effectively under one/20th that of cigarette smoke.
