Chairman Bill said "Instead of smoking, I vape in my e-cigar propylene-glycol with nicotine that has flavourings added - banana, vanilla, etc.
Of late I have been 'cutting' the e-liquid with BP glycerine to make it go further, which does tend to dry out the mucous membranes a tad. However, my question is about added flavourings.
Given the e-liquid is vaporised prior to inhalation, what chemicals that commonly appear in food flavourings should I keep well clear of. I believe caramel bungs up the works of the e-cigar due to the sugars, but I'm led to believe that food flavourings can also have some added chemicals that can undergo a transition when vapourised and could be dangerous.
Blowed if I know, Bill.
It's not that a particular flavouring is dangerous. I am assuming that they are not burnt in the normal cigar/cigarette sense. If that is the case, they are all dangerous.
If the vaporisation is not at a particularly high temperature, they should all be OK.
