Nicotine Free 0mg
Nicotine free e-liquid, in two quite different situations.
Most of what is here is shortfill - a 100ml bottle sold at 0mg with room left at the top for nicotine shots. Two 18mg shots take a full 100ml to 3mg, one gets you roughly 1.5mg. It is how sub-ohm vapers buy in bulk, and it is cheaper per ml than anything else on the shelf.
The rest is genuinely nicotine free and meant to stay that way - for people who have tapered all the way down and kept the habit, which is more common than you would think.
If you are still on nicotine and just want a big bottle, buy the shortfill and the shots together.
