Nicotine by product: cigarettes, vapes, pouches, and gum
Once nicotine is absorbed, its roughly 2-hour half-life is similar regardless of how it was delivered. What actually differs between cigarettes, vapes, pouches, and gum is the absorbed dose and how quickly it enters the bloodstream, which is what this page compares.
Absorbed dose by product
A single cigarette delivers a relatively small absorbed dose, around 1 to 1.5 mg, despite containing more nicotine than that, because much is lost to smoke and incomplete absorption. Standard nicotine pouches and gum are commonly labeled at about 4 mg, while vaping varies enormously by device, liquid strength, and how a person uses it, making the label and habit the only reliable guide.
Speed of absorption
Delivery speed differs even when the dose is similar. Inhaled nicotine from cigarettes and many vapes reaches the bloodstream within seconds, producing a sharp peak. Pouches and gum absorb more slowly through the lining of the mouth over many minutes, producing a gentler, more drawn-out rise. The half-life of what is absorbed, however, stays around 2 hours across all of them.
Using the presets
The calculator's nicotine presets reflect typical absorbed doses: about 1.1 mg for a cigarette, 4 mg for a pouch or a piece of gum, and roughly 11 mg for half a pack. If your product differs, enter the absorbed milligram amount directly. The decay curve then applies the same 2-hour half-life to whatever starting dose you provide.
