ACAS also go on to say that it could impose a large health risk to workers if e-cigarettes are banned from offices and workplaces as many people use e-cigarettes as a way to stop smoking traditional tobacco cigarettes. Tobacco cigarettes can contain “more than 7,000 chemicals when burned”, with at least 69 of these being known to cause cancer and many others being poisonous. Supportive employers of vaping can take a stance to improve their employees health by allowing e-cigarettes as a plan to stop smoking as recent studies from Public Health England have shown that they are around 95% less harmful.
ACAS state: preventing the use of E-cigarettes at work may hinder those who use them to stop smoking, particularly if they are required to smoke them in designated smoking areas together with cigarette smokers” which would lead to passive smoking.
Passive smoking, also known as second-hand smoke, is estimated to kill “over 12,000 people in the UK from lung cancer, heart disease, stroke and the lung disease Chronic Obstructive Pulmonary Disease (COPD).”
