Vaping does normalise smoking
'Normalisation' is a perfectly good argument against vaping. The tobacco companies will always support anything that promotes the acceptability of smoking tobacco or raises its profile, no matter how subtly. Get 'em young !
Fifty years ago, one of the ploys was 'sweet cigarettes', a sugary edible lookalike. Of course, it didn't make any five year old dash out, buy a packet of 10 cancer sticks and start puffing away, but it helped to sow the seeds of association, implying that one day you'd be old enough to use the real thing.
Today they'd love vaping to be allowed everywhere, including No Smoking areas, because it makes it harder to spot anyone smoking tobacco: try distinguishing a vaper from a smoker on CCTV. Fortunately, this has failed because almost all organisations include vaping in smoking bans.
Besides, who knows what's in the vaping goo? Of course, they'd never flavour it with anything addictive or something that research showed created a craving for tobacco, would they?
