Hopkins researchers want to learn about your general well-being and the long-term effects of e-cigarette use on your oral, lung, and heart health. Participants will be asked to provide a sample of their saliva, urine, cheek swabbing, gum plaque, and blood at three study visits over two years and answer brief monthly surveys for two years. You will also need to complete a spirometry test and a blood pressure measurement. You may be compensated up to $50 per visit for time and travel and receive a free Fitbit Charge 2 that is yours to keep.
