When "smoking" an e-cig, you are not exposed to the same levels of carcinogens and toxins associated with conventional smoking. The e-cig emits a vapour which is primarily water/steam which quickly dissipates meaning there is no lingering smoke odour on clothes, in the atmosphere or on your breath.

Therefore, there are none of the risks associated with passive smoking.

The e-cig beats the smoking ban because of the above points, and it is not actually smoking, ( there is nothing burning like a cigarette ), therefore it is legal in public places where a smoking ban exists, e.g. Pubs, bars and restaurants

This means electronic cigarettes are a healthier option for smokers.
