The problem that vaping will always have is that it fails the duck test.
If it looks like a duck and quacks like a duck, then it's a duck.
Cigalikes look like a cigarette and the vapour looks like smoke, so people just see it as smoking but different slightly. We've been conditioned as a population to see smoking as a very undesirable thing to do and so vaping by virtue of the duck test also gets roped in to the same category no matter what the scientific evidence to the contrary.
I'm a vaper and have been for many years and I've lost count of the amount of people who have come up to me and told me that it's worse than smoking, or it will explode, or I'm killing them by standing in the open air with my vape.
