What is the highest % nic you can put in your juice

28mgs

If you use a sub-omg device I wouldn't go over 20, the throat hit would be awful and if you chain vape you would likely get nic sick. A pod system designed for higher nic should be good at 50-60

51 Vape carries nic salts that are available at 25 and 50. Other than that, ive mostly seen 0, 3, and 6

The highest nicotine levels I've seen in 51Vape and other local stores is 6mg and maybe 12mg.

I imagine that it depends on the kind of juice, and the device you're using. I buy my juice there and if it doesn't have enough nic they can add more to it.
