In most cases, the e-cigarette does not burn tobacco, but vaporizes a liquid containing nicotine. The main component is in most products of propylene glycol, which is responsible for the vapor effect. It is the same substance that comes from the fog machine in nightclubs or theaters. Often to the electronic cigarette can be added flavors such as menthol or vanilla. Researchers at the University of San Diego counted around 7700 different flavors of tiramisu to forest fruit.
Is the e-cigarette dangerous to passive smokers?
It is already not clear how harmful is the electronic steaming for the consumer, the risk to third parties is even more difficult to estimate. Because it is also a question how much of the ingredients on the steam are being released in and being spread.
For the E-cigarette is the fact that the standard products do not constantly hinnebeln right but release the steam just at your fingertips. And it seems to be that in many cases contain less contaminants are released than from a normal cigarette.
Tunga Salthammer, chemist at the Fraunhofer Wilhelm Klauditz Institute in Braunschweig, has found in a study, “that the released by the consumption of e-cigarettes in the ambient air quantity of many organic compounds is less than that of conventional cigarette smoke.” The amount of propylene glycol is higher in the electronic cigarettes.
Another difference, according to the experts, is the nature of the particles as SZ said tiny particles in the exhaled vapor of e-cigarette “dissolve with time and go over into the gas phase, the particles in cigarette smoke are against solids.. They remain as such in the air.”
However, BFR assumes that bystanders could be jeopardized by the fumes. The Institute refers primarily to the fact that consumers experimented with refillable cartridges and could also use harmful substances. No one can therefore know what the e-smoker blows right next to him in the air.
