Does vegetable glycerine turn into a toxic substance?
No, vegetable glycerin (VG) is considered safe and is widely used in the food industry, but it requires proper use to remain harmless in your tank. Its role is essential: it stabilizes your e-liquid, softens the throat hit, and generates the dense clouds we love, while ensuring a consistent blend of flavors and nicotine.
The real danger only occurs in the event of thermal degradation: if heated beyond its limits, it can decompose into acrolein, a compound that is irritating to the respiratory tract. Rare cases of respiratory allergies also exist, manifesting as coughing or itching. To vape safely, simply follow the recommended wattage settings and use the VG ratio suited to your specific coil to prevent any accidental overheating.
