do vapes have calories

Short answer: technically yes, but practically no.

The science:

  • VG (Vegetable Glycerin) and PG (Propylene Glycol) are carbohydrates and do contain calories — roughly 4.3 kcal per gram for VG and 4.0 kcal per gram for PG
  • However, you are inhaling these, not digesting them. Calories only count when your body metabolizes them through the digestive system
  • The amount you actually absorb is negligible — comparable to breathing in air near a bakery

Real-world perspective:
If you vaped 5ml of 70/30 VG/PG juice per day (heavy use), the theoretical maximum would be around 15-20 calories. In practice, it’s close to zero because:

  1. Most of it gets exhaled
  2. What stays in your lungs isn’t digested like food

Bottom line: Vaping will not affect your diet, caloric intake, or weight. If anyone tells you they gained weight from vaping, it’s not the vape. :grinning_face_with_smiling_eyes:

Now, appetite suppression from nicotine — that’s a different story, but calories themselves? Don’t worry about it.

VAPES typically do not contain calories, but there are exceptions depending on the composition of the e-liquid. The main ingredients of e-liquid are usually propylene glycol (PG), vegetable glycerin (VG), flavorings, and nicotine. Strictly speaking, both PG and VG are calorie-containing substances, as they are forms of alcohol and glycerin. If consumed in large amounts, they can provide calories.
