Freebase Nicotine is the original Nicotine in E-Liquids, it is mostly suitable for people who like to puff little and often throughout the day since freebase E-Liquids feel harsher on the throat. They are available in lower nicotine levels and also nicotine-free, freebase E-Liquids are great for sub-ohm devices, or box mods paired with bigger atomizers such tanks and RDAs. As freebase nicotine has a lower degree of nicotine concentration, they are best used with Sub-Ohm Devices. The larger coil, higher power, and lower resistances of sub-ohm devices allow for freebase nicotine to be vaporized within the juice, delivering a small dose within a large cloud of vapour.
