After consenting to the study, the subjects are examined using Laser Doppler Camera. The skin blood flow of the extremities is determined as a reference value. Laser Doppler Imaging produces images of the blood flow using the perfusion units (PU). All measurements are taken under controlled vital parameters (body temperature, systolic and diastolic blood pressure, heart rate) and controlled room temperature as well as 15-minute acclimatization of the subjects. For smokers or vapers, the perfusion is measured again after consuming a cigarette or an e-cigarette respectively. The difference of blood flow after smoking or vaping is calculated using both measures. The total duration of the study per subject is approximately 25-30 minutes.
