Stevia is NOT a potentiator, it is a sweetener and flavor enhancer like ethyl maltol and sucralose. This doesn't mean you can't use it, but don't mislead people.
One of the categories of additives, potentiators enhance the total seasoning effect, generally without contributing any taste or odor of their own. They are effective in minute doses-in parts per million or even less. A potentiator produces no identifiable effect itself but exaggerates one's response. They alter the response of the sensory nerve endings on the tongue and in the nose. As far as I know,
vape Wizard and Magic Mask are the only potentiators for
vaping.
