Yes, VG (Vegetable Glycerin) is thick.
VG is significantly thicker than PG (Propylene Glycol), another common ingredient in e-liquids. This difference in viscosity affects how it's used in vaping. Because of its thickness, VG requires more heat and power to vaporize effectively. Using high-VG e-liquid in a mouth-to-lung (MTL) device that isn't designed for it can lead to coil gunking and reduced flavor, vapor production, and nicotine delivery.
Here's a comparison:
| Feature | PG (Propylene Glycol) | VG (Vegetable Glycerin) |
|---|---|---|
| Thickness | Thin | Thick |
| Vapor Production | Lower | Higher |
| Throat Hit | Stronger | Milder |
| Flavor Carry | Better | Less Efficient |
| Coil Gunking | Less | More |
In summary, VG's thickness is a key characteristic that dictates its performance and suitability for different vaping devices and preferences.
