Yes, e-liquids used in vaping contain a small number of calories, primarily from their main ingredients:
- Vegetable Glycerin (VG): Approximately 4 calories per gram.
- Propylene Glycol (PG): Approximately 4 calories per gram.
Flavorings and sweeteners may add minimal additional calories, but their impact is negligible. Overall, a typical 1 mL of vape juice contains about 4-5 calories.
However, it's important to note that when vaping, these substances are inhaled rather than ingested. Current research suggests that the body does not absorb significant calories through inhalation, meaning vaping is unlikely to contribute to your daily caloric intake or affect your weight.
