At the moment there is little data about the health effects of eciggs,
Which is why people like the WH0 are erring on the side of caution
Ongoing studies point to them being the most effective aid to quit smoking there is and much less harmful than fags, (irresponsible headlines in crap papers like the Sun and Telegraph aside)
Obvs it will be 30 years before we know what the long term effects will be but science has come a long way from the 50s and the kind of stunts the tobacco industry pulled back then would almost impossible to get away with now.
They also have the potential to much better control what is exhaled than regular fags
As a recreational drug delivery system they are probably the future. So stuck it up and get used to it !
But still the guys a dick and of have a weird with him
