How many calories per puff of vape
2025-04-23
The calories ingested each time you smoke an e-cigarette (one puff) are extremely low, almost negligible, usually less than 0.2 calories. The following is a detailed analysis:
1. Calorie sources
The main ingredients of e-cigarette oil are:
Vegetable glycerin (VG) and propylene glycol (PG): Both have a calorie content of about 4 calories/gram, but the amount inhaled each time is very small (microgram level).
Nicotine and flavors: Almost no calories.
2. Actual calculation
Assumption: 1 bottle of 30mL e-liquid (about 30 grams), the total calories are about 120 calories (30g × 4 cal/g).
Assumption: This bottle of e-liquid can be smoked 600 times (common estimate), then:
Calorie per puff = 120 calories ÷ 600 ≈ 0.2 calories.
(It may actually be lower, because the e-liquid is not completely absorbed by the human body.)
3. Comparison Reference
100 puffs ≈ 20 calories (about the calories of a slice of cucumber).
Even if you take 500 puffs a day, the calorie intake is only equivalent to a small sip of cola (about 5-10 calories).
Key conclusion:
The calorie intake of e-cigarettes is negligible and has no actual effect on weight or diet.
