| Typical dose | NRT products typically deliver 2–4 mg of nicotine per piece of gum/lozenge or 7–21 mg/24h from a transdermal patch — doses studied for cognitive effects in non-smokers were usually lower (around 2–7 mg) than the standard doses used in smoking-cessation therapy | — |
| Form | Chewing gum or lozenge (faster, shorter action) or a transdermal patch (slower absorption, a more stable level throughout the day) | — |
| Average price | 25–50 zł za opakowanie gumy lub pastylek (ok. 30 sztuk); plastry 40–70 zł za opakowanie na 1–2 tygodnie | — |
| Monthly cost | ok. 60–150 zł/miesiąc przy regularnym stosowaniu | — |
| Time to effects | A cognitive effect after a single dose is noticeable within 15–30 minutes and lasts 1–2 hours (gum/lozenge), or is distributed steadily over many hours (patch); tolerance to the cognitive effect can develop after just a few days to a couple of weeks of regular use. | Not applicable — HRV is a monitoring indicator, not an intervention; changes in the trend become visible after several days to weeks of observation. |
| Who it's for | People already regularly using nicotine replacement therapy to quit smoking who notice an additional cognitive effect as a side effect of the therapy | Athletes wanting to objectively monitor training load and recovery |
