Salt Nicotine vs. Freebase
The difference between Salt and Freebase Nicotine is based off of the hit the nicotine delivers. Salt nicotine is meant for use in vapes above 1ohm of resistance. These are usually in higher nicotine levels and deliver nicotine to the blood stream much faster than a freebase nicotine. Freebase nicotine is slower to hit the blood stream and is typically used in 'sub ohm' devices. Be sure to check which type of nicotine is right for your device and coil.
