Summary

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.

Detailed description

Smokers of cigarettes with about 16-30% ventilation in their conventional cigarettes who meet eligibility criteria will enter 3 weeks of monitoring of usual brand smoking. Subjects will then be randomly assigned for a period of 6 weeks to one of two conditions: 1) ventilated cigarettes; or 2) unventilated cigarettes. Subjects in each condition will be unblinded to simulate real world conditions. Subjects are provided with a debit card (ClinCard) that has been loaded with the appropriate amount of money to cover self-purchased usual brand cigarette in baseline and the assigned study cigarettes during intervention. Weekly telehealth visits will be conducted during baseline and the 6 weeks on study cigarettes to collect study measures, followed by a one month follow-up.
