i recently purchased some juice that's 6mg/ml salt nic and im just curious if its safe or not to use it in a sub-ohm set up. i normally vape 6mg of freebase in my drop rda with a dual coil set up at about 0.2-0.3 ohms at roughly 60-80 watts. so i guess what im asking is if it would be safe to use the same set up just with 6mg of salt nic instead of 6mg freebase while puffing on it quite frequently.
