Although the word dependence is more suitable when discussing “addiction” to nicotine outside of smoke, in everyday (i.e. less precise) language, nicotine salt is addictive. Other components of smoke do enhance the addictiveness of smoked tobacco, but nicotine itself is still the primary addictive component of smoke. In short, nicotine salt e-liquid is just as addictive as freebase nicotine e-liquid, and if it leads to sharper spikes in blood nicotine levels (which Pax’s data suggest it does) it could actually be slightly more addictive than normal e-juice.
