Yes, vaping has calories. Do you need to stress over it? It’s not really.
It is important to note that most of the ingredients in the liquids can be described as vegetable glycol (VG) and propylene glycol (PG). Because both are additives to food products, they all have information on their nutritional value, which can be easily found online. The two VG and PG have about 4,500 calories each, or milliliter.
The other two components that comprise vape are flavors and nicotine. They contain less than one percent of the ingredients found in vape, so the PG and VG proportions can be as high as 100.
Flavorings typically contain only a tiny amount of sugar. They are generally artificial flavorings and are not flavorings such as fruit syrups. The caloric nicotine content is typically not determined – it’s not intended for consumption in food. It’s also hazardous to consume nicotine.
While that 1% may be the thing that sets many nicotine-rich vapes, it will have little to do with calories as it’s a tiny percentage of vapes. Even if it were pure sugar, it would only be four calories for a 100ml vape!
Finally, whether the calories present in vapegetng efficiently absorbed and used through the lungs is an issue that hasn’t been researchers have been plenty of studies on the various aspects of vapes, from the bioavailability and toxicity of nicotine salts and freebase nicotine to the dangers of flavoring agents.
As few calories are in vapes, it’s not something to be concerned about.
