Brief Summary:

Because e-cigarettes do not contain or burn tobacco, they do not appear to deliver the known toxins found in conventional cigarette smoke.However e-Cigarettes with low dose of tobacco were found to have immediate adverse physiologic effects after short-term use that are similar to some of the effects seen with tobacco smoking.

In this study we wanted to assess the short-time effect of one e-cigarette with no tobacco vs a "traditional" cigarette.

10 n-smoking subject and 10 actual smokers will be enrolled in the randomized trial.


Condition or disease Intervention/treatment Phase
Individuality Device: e-cigarette Device: cigarette Not Applicable

Detailed Description:

On day 1 the subjects will be asked to smoke either the e-cigarette or a "traditional" one for 5 minutes. On day 2 the subject will be ask to smoke for 5 minutes the other kind of cigarette.

Exhaled Nitric Oxide will be measured in a sitting position with a nose clip using an analyzer equipped with a software program. The patient will be instructed to inhale as deeply as possible to total lung capacity through a filter mouthpiece and consecutively exhale at a mouth fl ow rate of 50 mL/s for 10 s. Three consecutive trials will be performed with a 30-s interval.

Dynamic Lung Volumes: Flows and lung volumes will be measured in the sitting position, a spirometry system (heated pneumotach, with the highest FEV 1 recorded in line with pulmonary guidelines. Spirometry will be measured according to the recommendations of the American Thoracic Society/European Respiratory Society task force guidelines. FEV 1, FVC, FEV 1 %, peak expiratory fl ow (PEF), and maximal expiratory fl ow (MEF) at 25%, 50%, and 75% of vital capacity will be measured. Each maneuver will be repeated for at least three technically acceptable forced expiratory fl ow curves.
