Nicotine Index methodology

NI is calculated only from verified mg nicotine per pouch. If only mg/g is known, no NI is assigned until pouch weight or mg per pouch can be verified.

NI 00 mg nicotine per pouchNI 10.1–3 mg nicotine per pouchNI 23.1–6 mg nicotine per pouchNI 36.1–9 mg nicotine per pouchNI 49.1–13 mg nicotine per pouchNI 513.1–20 mg nicotine per pouchNI 6>20 mg nicotine per pouch

What NI does not measure

NI does not measure blood nicotine, dependence risk, absorption speed, pH or subjective intensity. These variables should be reported separately when reliable data exist.

Next step

The next version can add verified products, pH where laboratory data exist, source-level provenance and comparisons between products sharing the same NI.
