Pouch labels state total nicotine content, not what reaches you. Pharmacokinetic studies find roughly 60% of the labeled nicotine is extracted during typical 30–60 minute use (randomized PK study, Nature Scientific Reports). We convert to cigarettes using ~1.5 mg absorbed per cigarette from the clinical literature. Pouches also deliver slower — peaking at 20–65 minutes versus 5–8 for smoking — which is why they can quietly stack up across a day.
Zyn caps at 6 mg in the US; some international brands go higher. If you moved from vaping to pouches and want to compare, run your old habit through the vape nicotine calculator — and if you're ready to step down, the taper plan generator works for pouches too.
