Another thing is, some of these flavors may not be entirely safe for long-term high-use
vaping. They contain things that are fine to eat, but not to inhale. Some chemical flavorings could be a bit risky, and any dark colors are both unnecessary and not a great idea. Coffee, chocolate, caramel for example will contain dark colorings to color sponge cake, but these are to be avoided when vaping.
A better choice would be something like Decadent Vapour's flavors, these are made specifically for vaping. Not too sure who carries DV flavors at the moment in the US, Totally Wicked and Liberty Flights would be good places to start.
