A word of caution for all Vape users

[Croesy Blue]

An important point that Croesy brought up is that there are people who use these with no history of smoking at all. Although perceived to be healthier than smoking, and therefore can be used as an interim step between smoking and completely quitting, they surely are worse for you than being a non-smoker (evidence needed to show this) and will (hopefully) be subject to the same public health promotion interventions and messages as tobacco smoking.

Exactly there is no way it has zero affect on health at all. It might even be small but the amount people do it just because it's "healthier" than smoking is shocking.
