Throat Hit Without Nicotine?
The throat hit, sometimes called the flash, is that scratchy kick you feel when you inhale nicotine e-liquid into your lungs. It’s a sensation every cigarette smoker knows, and it’s exactly what many people feel they need. There are additives out there, for example from Flavourart, that are meant to mimic that throat hit, and plenty of DIY mixers still have a little bottle 
kicking around at home — because, honestly, it doesn’t do a great job.
Another option is menthol. You can literally add menthol to any e-liquid. Fruit flavours with menthol can still taste great, but vanilla e-liquid with menthol? Not really. The alternative is caffeine.
There are detailed guides on caffeine and the ratio you need to add to your e-liquid to create a flash when vaping. But one thing shouldn’t be forgotten: caffeine can’t replace nicotine. Whether you want to try it is up to you. Personally, I’d rather keep my caffeine in a cup.
Have fun reading up on it or giving it a try!
