About this trial

This prospective study assesses the pulmonary and cardiovascular effets of vaping in adult electronic cigarette users with biannual visits and a 5-year follow-up.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age 18 years or older

Daily electronic cigarette user

No respiratory infection in the 4 weeks before a visit

Disqualifiers

Women who are pregnant or breast-feeding.

Trial population

We seek to recruit 250 volunteers from the community with twice-a-year visits for a 5-year follow-up. We will recruit healthy volunteers as well as volunteers who have been previously diagnosed with chronic illness.

Trial outcomes

Primary outcomes

1

Number of participants who vape daily with impaired lung volumes.

Participants will perform plethysmography assessments to measure changes in lung volumes. Data will be expressed as a percentage of predicted values.

Time frame
Every 6 months for 5 years
2

Number of participants who vape daily with impaired lung diffusion capacity.

Participants will perform diffusion capacity of the lung for carbon monoxide (DLCO) measures to assess changes in lung diffusion capacity. Data will be expressed as a percentage of predicted values.

Time frame
Every 6 months for 5 years
3

Number of participants who vape daily with impaired spirometry.

Participants will perform spirometry tests measures to assess changes in forced expiratory lung volumes. Data will be expressed as a percentage of predicted values.

Time frame
Every 6 months for 5 years
4

Number of participants who vape daily with airway hyperresponsiveness.

Participants will perform methacholine provocation challenge measures to assess changes in airway hyperresponsiveness. Data will be expressed as the methacholine concentration inducing a fall of 20% of forced expiratory volume in the first second assessed (PC20).

Time frame
Every 6 months for 5 years
