If you're a health-conscious vaper who tracks every calorie you eat and drink to manage your weight, you might be wondering: 'Does vaping have calories?' People on a diet usually don't even think that the smooth puff they take to unwind could be adding to their calorie intake. 

But the question "Do vapes have calories?" has created quite a stir among fitness-conscious vapers. If you've ever wondered whether it's something worth considering, we're here to explore the facts about vaping calories and how they might affect your health and weight goals. Let's get into it!

Do disposable vapes have calories?

A disposable vape pen is one of the most popular vaping devices, which involves inhaling vaporized cannabis oil. These pen-like devices feature a cartridge containing cannabis oil. 

So, if you are wondering, do disposable vapes have calories? The answer is yes, but it is a relatively small amount of calories that won't significantly impact your health or weight. Vape calories are minimal, but knowing about the content in vape juice is key for those worried about vaping and weight gain.

Cannabis vape pens themselves don't contain significant calories. However, disposable vape pens use prefilled cartridges containing cannabis oil, which are extracts from cannabis plants and may contain trace amounts of ingredients that could contribute to the caloric count. Here's a breakdown of ingredients found in cannabis oil used in vape pens:

  • Carrier Oil

To dilute the cannabis oil and create a smoother vaping experience, some cannabis oils are blended with carrier oils like vegetable glycerine, propylene glycol, or MCT oil. Though they don't contain significant calories, they do contribute a small amount. 

For instance, the raw form of propylene glycol (PG) and vegetable glycerine (VG) do have some caloric content, but their contribution to calorie intake is negligible when used in vaping. 

So, how many calories are in a disposable vape pen? There are 4 calories in one milliliter of propylene glycol. An average vape cartridge contains 0.5–1 mL of e-liquid, so you can expect around 2–4 calories per cartridge.

Similarly, MCT oil is derived from palm oil or coconut oil and does have caloric content, but its quantity used in a vape pen cartridge is usually minimal. 

  • Cannabinoids: 

Cannabinoids play a crucial role in the effects associated with cannabis. While they don't contain significant calories, primary cannabinoids like THC and CBD are fat-soluble compounds, meaning they can be stored in the body's fat cells. However, they do not directly impact your caloric intake.

  • Flavorings

Some disposable vape pens contain flavoring agents to enhance the taste, which are often derived from food-grade additives. These additives may contain a small amount of calories, but they don't contribute to the overall calorie content of cannabis oil. Their amount is usually minimal and doesn't contribute to the overall calorie intake.

  • Terpenes: 

Terpenes give the distinct aroma and flavor to the cannabis oil and play a crucial role in enhancing your overall vaping experience. Terpenes found in cannabis oil have no calories. 

In short, using a vape pen doesn't affect your calorie intake, as vape juice contains so few calories. With 0.5 to 1 mL of e-liquid, an average vape cartridge usually contains between 2 and 4 calories. That means if you finish one vape cartridge in a week, you'll have ingested the calorie equivalent of:

  • Less than one cup of black coffee 

  • A spoonful of miso soup

  • One baby carrot

  • One cherry tomato

  • 1 sugar-free mint

Can you gain weight by vaping?

No, vaping doesn't add many calories and make you gain weight. Some may wonder if it could increase your metabolic rate, reduce hunger, and indirectly impact your weight. Some anecdotal evidence suggests that it may help manage the craving for snacks. However, these effects have not been proven and require further research. 

However, if you are new to cannabis vaping, switching from cigarettes to e-liquid can make you hungry and can be the main culprit behind your late-night fridge raids. THC can rev up your metabolism, and its continual activation of CB1 receptors may also heighten your appetite, leading to those infamous munchies. When they snack more frequently, they may experience weight gain.
