juice with no nicotine has no throat hit. But there are some TH additives you can use (Flavourart makes QHit, vapornice has something else, Totally Wicked has a strong capsacin i.e. pepper juice). Then there are some flavors that add some thriat sensation - mint, menthol, cinnamon, ginger, pepper (FreedomSmokeUSA has pepper eliquid), other spices, some liquor flavors.
But since they don't work, why offer it as an alternative to "good" throat hit?
