Electronic cigarettes and regulation

Sir, – Can we be sure that electronic cigarettes do not cause harmful side-effects to bystanders who are exposed to them? Apparently the laws on smoking, advertising and promotion do not apply, or are not enforced, in the case of so-called electronic and vapour cigarettes. Pop-up stalls and vendors sell them without obvious restrictions. I have seen smokers “light up” their e-devices in restaurants and shopping malls with no obvious concern for their own or anyone else’s health or the sensitivities of those around them. Can we be sure that the sale and use of these devices should remain unregulated? – Yours, etc,
