Article Synopsis
  • Many oral nicotine pouches (ONPs) use synthetic nicotine, which includes a mix of S-nicotine and R-nicotine, but most tobacco-derived nicotine is primarily S-nicotine, making R-nicotine's effects mostly unknown.
  • In a study involving 18 adult smokers, participants tested ONPs with more than 99% S-nicotine and racemic nicotine, measuring nicotine levels in their blood and product appeal after usage.
  • Results showed that ONPs with over 99% S-nicotine had significantly higher nicotine concentrations in the blood, although perceived product liking and withdrawal relief were similar across both types of ONPs, with some reporting more adverse effects from the S-nicotine pouches.
