Study Information

AMR Lexington is currently enrolling volunteers 21-45 years of age who are daily cigarette smokers and would be willing to use an oral tobacco-derived nicotine pouch, or not use any tobacco products during their time in the study. Volunteers must also have the ability to stay in-clinic for 11 straight days.

The study intends to determine changes in exposure to selected tobacco constituents by measuring biomarkers in adult smokers who completely switch from smoking to use of on!® nicotine pouches compared to those who continue smoking cigarettes or stop using all tobacco products during the clinical trial.

Duration: Up to 5 weeks

Number of visits to AMR Lexington: A screening visit followed by a 11-day in-clinic stay

Reimbursement: Qualified participants receive up to $3,725 for your time and travel

Study detail:

  • Volunteers are daily cigarette smokers ages 21 to 45
  • Volunteers must have the availability to stay in-clinic for 11 consecutive days
  • Other criteria also apply and will be addressed later in a qualifying questionnaire
