Sponsor's own description
This open label, between-subject, randomized multi-center pilot study will assess the feasibility of conducting a study remotely with telehealth visits to assess the effect of cigarettes with minimal filter ventilation vs. moderate filter ventilation on smoking behavior and biomarkers of tobacco toxicant exposure. Subjective measures, alveolar carbon monoxide, blood pressure and cigarettes per a day will be collected remotely. Biological samples will be collected at home and mailed to the study clinic.
