Jan. 13, — A new cohort study among 103,642 adults found that current use of cigars was associated with increased risk of stroke, atrial fibrillation and heart failure, while current pipe use was associated with increased risk of heart failure. Users of smokeless tobacco products had increased risk for myocardial infarction and mortality due to coronary heart disease.
This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least one noncigarette tobacco product ranging between 1948 and 2015. This study was approved by the Johns Hopkins School of Medicine Institutional Review Board
This study identifies distinctive cardiovascular risks associated with the use of noncigarette tobacco products, underscoring the substantial public health implications and highlighting the need for stringent regulatory measures.
