Tag: Nicotine metabolism

Nicotine is primarily metabolized by the liver and excreted by the kidneys, with a relatively short half-life in the bloodstream. While hydration is a crucial aspect of this natural detoxification process, the idea that simply drinking a lot of water can instantly flush out all nicotine is a misconception.

While the liquid in a vape contains calories from its base ingredients, the act of vaping does not contribute significant calories to your diet because the body does not absorb them through the lungs during inhalation.

According to a 2005 Scripps Research study, the liver enzyme CYP2A6 is responsible for metabolizing approximately 80% of nicotine, making it central to understanding tobacco addiction and dosage requirements. However, nicotine's effects extend beyond its own metabolism, with both direct and indirect influences on a wide array of enzymes throughout the body.

According to nutritional data, the primary ingredients in e-liquid—propylene glycol and vegetable glycerin—do contain approximately 4 calories per gram. So, while the answer to 'Is there a calorie in a vape?' is technically yes, the practical impact on your daily intake is so small it is considered negligible. This minimal caloric content is one of the most surprising facts about vaping and its relation to dieting.

While vegetable glycerin, a key component in e-liquid, contains approximately 4.32 calories per gram when ingested, the number of calories your body actually absorbs from a single vape hit is considered functionally zero. Understanding this distinction is crucial for anyone who has ever wondered, do vape hits contain calories?

An estimated 12.3% of U.S. adults are current nicotine users, and for many, a lingering question is, "should I eat before taking nicotine?". Health experts and user experiences suggest that consuming food beforehand is crucial for mitigating adverse effects, especially on an empty stomach.

Chemically, pure nicotine contains no calories because it is a stimulant alkaloid and not a source of nutritional energy like fat, protein, or carbohydrates. A common misconception is that nicotine has a caloric content, when the reality is far more complex and related to how the substance affects your body's energy balance.

While e-liquids contain ingredients with calories, your body does not absorb them in the same way as food. Therefore, in answer to the question, **do I gain calories from vaping?**, the direct caloric impact is negligible, though other factors may influence your weight.

A 1993 study in the New England Journal of Medicine analyzed common vegetables and black tea, and found measurable amounts of nicotine, but importantly, cotinine could not be detected in the samples. Understanding whether foods contain cotinine is crucial for distinguishing between dietary intake and exposure from tobacco products, for which cotinine is a primary biomarker.
