Description
The FDA is planning regulatory actions to limit nicotine levels in cigarettes as far as it is not reduced to zero. The strategy is designed to reduce the addictiveness of cigarettes. However, nicotine related effects of the cigarettes with reduced nicotine content on various body systems are largely unknown. Following formal implementation of the regulatory policy what cardiovascular effects of reduced nicotine cigarettes, also called very low nicotine content cigarettes (VLNCC) are expected to persist is important to determine. This study will determine the cardiovascular effects of VLNCC such as change in heart rate, autonomic functions and indices of ventricular repolarization in smokers. Participants will be asked to smoke two VLNCC and one normal nicotine content cigarette (NNCC) while we will be recording their electrocardiogram (ECG) to see a change in heart rate, heart rate variability and indices of ventricular repolarization.
