Can a phone study track how cigarette design changes smoking habits?
NCT ID NCT04514471
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a remote, telehealth approach can work to study how cigarette filter ventilation (the tiny holes in the filter) affects smoking behavior and exposure to harmful chemicals. 64 adult smokers participated from home, using their own devices for video visits and mailing in samples. The goal was to see if this method is practical, not to test a treatment.
