Okay, so, I’ve been seeing this question pop up everywhere: how many calories are in a vape? And you know what? I got curious too. So I decided, why not just figure it out myself? No fancy labs or anything, just me, my vape, and a bit of digging.
First off, I grabbed my usual vape juice. I checked the label, but of course, no calorie info. Not surprising, really. Then I thought, “Okay, what’s even in this stuff?” It’s mainly propylene glycol (PG), vegetable glycerin (VG), flavorings, and nicotine, right?

My Experiment Begins
- I started by looking up each ingredient. I learned that PG and VG are used in some foods, so they must have some calories. I found some numbers online, nothing too exact, but it gave me a ballpark.
- Next, I tried to figure out how much of each ingredient was in my vape juice. The bottle gave me the PG/VG ratio, which was a start. The nicotine content was easy, also listed. But the flavorings? That was a mystery. I guessed it’s probably a small amount, calorie-wise.
- Then came the hard part – how much vape juice do I actually use in a day? I usually refill my vape tank once or twice, so I filled it up, weighed it, vaped all day like normal, and then weighed it again at night. Did this for a few days, just to get an average.
With all this info, I did some rough calculations. It wasn’t super scientific, but it gave me an idea. And guess what? The numbers were pretty low. Like, really low. We’re talking a few calories per day, maybe the same as a stick of gum or a small piece of candy. But I also realized something important, it’s not like eating those calories. The calories in vapor are mostly exhaled and not absorbed by the body in the same way as food.
So, what’s the conclusion? Honestly, I’m not a scientist, but from what I gathered, the calories in a vape are minimal. It’s probably not something to worry about if you’re counting calories. But hey, this was just my little experiment. If you’re really concerned, maybe talk to a doctor or something. But for me, I’m just gonna keep vaping and not stress about the calories.
