Differences between Nicotine Salts & Freebase Nicotine

Generally speaking Freebase nicotine is going to offer a thicker viscosity, more of a throat hit and will typically come in lower concentrations. Considering Freebase nicotine usually maxes out around 12mg/ml it’s best to use in Direct-to-Lung devices. Salt nicotine is the counterpart to Freebase nicotine. It will typically be a thinner viscosity, provide a smoother throat hit but usually only come in higher concentrations around 25-50mg/ml. For this reason Salt nicotine is better used in Mouth-to-Lung devices
