NCT07829939

Brief Summary

The goal of this clinical trial is to understand how using oral nicotine pouches effects the body in healthy volunteers. The main questions it aims to answer are:

  • use 3 different strengths of ONPs (0 mg, 3 mg, 6 mg) and their usual inhaled nicotine product (cigarette or e-cigarette/vape)
  • visit the hospital research ward on 4 separate days for 8 hours each day
  • use one of each of the products in a randomized order (by chance, like flipping a coin) on each of the 4 hospital study days

Outcome Measures

Primary Outcomes (1)

  • With multiple use of ONPs throughout the day, participants will titrate their intake of nicotine to be similar to or higher than that seen with cigarette smoking or vaping.

    This will be assessed by comparing ratios of nicotine area under the plasma nicotine concentration time curve.

    7 hours post-dose

Secondary Outcomes (2)

  • With multiple use of ONPs throughout the day, participants will experience satisfaction, psychological reward and relief of withdrawal symptoms similar to that seen with cigarette smoking or vaping.

    Pre-dose until 7 hours post-dose.

  • Cardiovascular effects among arms using heart rate as a measure

    Pre-dose until 7 hours post-dose
