Featured in the Johns Hopkins Newsletter , a study published in the Journal of the American Heart Association found that e-cigarettes not only deliver nicotine which can lead to addiction, but can lead to an increased risk in cardiac arrest and possibly cardiac death.
According to the study, nicotine induces the sense of pleasure and excitement once it enters the body. When nicotine reaches the brain, it instructs the brain to release adrenaline. Adrenaline controls the heart rate and blood pressure in “states of strong emotion.” Recurring exposure to nicotine leads to a prolonged state of an increased heart rate. In the long term, this can lead to an abnormal heart rate variability (HRV). With HRV, stress is put on the heart, which increases the risk of experiencing a heart attack or a stroke.
