VAPORS study: Participants needed

All e-cigarette users and male non-users are needed for an observational research study. Participants will provide a sample of their saliva, urine, cheek swabbing, gum plaque, and blood at three study visits over two years and briefly answer monthly surveys for two years. They will also need to complete a spirometry test and blood pressure measurement. Eligibility requirements are on the study's website.

Compensation is up to $50 per visit for time and travel, and participants will receive a free Fitbit Charge 2 that is theirs to keep.
