0 calories in a vape hit
A vape hit contains zero calories because it delivers nicotine, flavorings, and chemicals-not edible substances. While vaping may suppress appetite temporarily, it doesn't provide energy or nutrients. Caloric intake only occurs if vaping oils (like CBD/THC-infused edibles) are ingested, not inhaled.
Why Vaping Has No Calories
- No digestion: Inhaled vapor bypasses the digestive system, where calories are absorbed.
- Chemical composition: E-liquids contain propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavorings-none of which are metabolized for energy.
- Nicotine's effect: May reduce appetite but doesn't replace food or add calories.
Calorie Comparison: Vaping vs. Other Nicotine Sources
| Method | Calories per Use | Notes |
|---|---|---|
| Vape hit | 0 | Inhaled, no metabolic energy. |
| Nicotine gum (1 piece) | 5-10 | Contains sweeteners/binders. |
| Cigarette (1) | 0-2 | Trace calories from burned tobacco (negligible). |
| Nicotine lozenge (1) | 2-5 | Minor calories from fillers. |
Exceptions: When Vaping Might Involve Calories
- CBD/THC vape oils: If labeled as "edible" and ingested (not vaped), calories may apply.
- Flavored e-liquids with sweeteners: Still 0 calories when inhaled, but may trigger cravings.
- Vape juice ingestion (accidental): PG/VG provide ~4 cal/g if swallowed (not recommended).
Does Vaping Affect Weight?
- Appetite suppression: Nicotine may reduce hunger, potentially lowering calorie intake.
- Oral fixation: Replaces snacking for some users, indirectly cutting calories.
- No direct fat loss: Zero-calorie vaping doesn't burn fat or boost metabolism.
