The side effects of vaping salt nicotine isn’t necessarily worse than freebase nicotine, but it still carries the same risks. Because it allows for higher nicotine concentrations and faster absorption, it can be more addictive.
While vaping salt nicotine avoids the tar and carbon monoxide found in cigarettes, nicotine itself can lead to dependence. Some users may also experience throat irritation from the added acids. Although likely less harmful than smoking, the long-term effects of vaping salt nicotine are still being studied.
