Main Outcome: How well your heart and lungs work during exercise.\n\nOther Outcomes: Lung function, blood vessel function, risk factors for heart disease, and body measurements.\n\nWhy is this study important?\n\nE-cigarettes are becoming more popular, but their health effects are unknown. This study will provide new information on whether e-cigarettes harm your health and if quitting for a short time can improve it.\n\nThis information can be used to create better public health policies about e-cigarettes.",[71],"Electronic Nicotine Delivery Systems",[73,74],"vaping","e-cigarette","NOT_YET_RECRUITING","2024-06-19",{"date":78,"type":79},"2024-06-26","ACTUAL",{"date":81,"type":65},"2024-06",{"date":83,"type":65},"2026-04",{"name":5,"class":6},1]
