Vegetable glycerin is safe for vaping nicotine.
Vegetable glycerin is a natural ingredient that is widely used to make vape juice. Glycerin can play a moisturizing role, making the smoke softer and taste better. At the same time, glycerin can also improve the stability of nicotine, making it more durable in vaping oil. Therefore, vegetable glycerin is considered a safe ingredient for vaping nicotine.
However, it should be noted that vaping nicotine still has certain health risks, and you should pay attention to safety when using it.
