Summary

E-cigarette use results in less intense and more pleasant breath odour compared to cigarette smoking. Switching to e-cigarettes may offer cosmetic benefits by reducing smoke odour.

Area of Science:

  • Otorhinolaryngology
  • Toxicology
  • Public Health

Background:

  • Cigarette smoke significantly impacts breath odour.
  • The effect of e-cigarettes on breath odour remains largely unknown.
  • Understanding these effects is crucial for public health and cosmetic considerations.

Purpose of the Study:

  • To compare breath odour between cigarette smokers (CSs), e-cigarette consumers (ECs), and non-smokers (NSs).
  • To assess acute changes in breath odour following product use.

Main Methods:

  • Pilot study involving 33 healthy subjects (11 CSs, 11 ECs, 11 NSs).
  • Breath samples collected at baseline and post-use.
  • Odour assessment by eight trained judges using smoke intensity and hedonic scales.

Main Results:

  • Significant differences in breath odour between CSs and ECs.
  • CSs exhibited higher smoke intensity and lower hedonic (pleasantness) values compared to ECs and NSs.
  • ECs' breath odour was comparable to NSs, with reduced smoke odour and more pleasant aroma than CSs.

Conclusions:

  • Acute use of e-cigarettes leads to significantly different breath odour compared to traditional cigarettes.
  • Switching from cigarettes to exclusive e-cigarette use may provide cosmetic benefits by improving breath odour.
  • Further research is needed to evaluate the long-term effects of e-cigarette use on breath odour.
