Impact of exclusive e-cigarettes and heated tobacco products use onmuco-ciliary clearance

摘要

Tobacco smoking impairs mucociliary clearance (MCC) efficiency as shown byprolonged saccharin test transit time (STTT). Avoiding exposure to tobaccosmoke from combustible cigarettes may restore MCC function and formersmokers have been shown to exhibit similar STTT as never smokers. The impacton STTT of switching from smoking to combustion-free tobacco products suchas e-cigarettes (ECs) and heated tobacco products (HTPs) is not known.
