E-cigarettes were first introduced into the United States in 2006 and have rapidly increased in popularity, often due to vape sellers’ claims that e-cigarettes are safer than traditional cigarettes, while also delivering the craved nicotine hit.
A study led by Dr. Holly R. Middlekauff of the David Geffen School of Medicine at the University of California in Los Angeles points out that e-cigarettes may certainly have a significantly lower number of carcinogens, but appear to be just as harmful to the heart as smoking.
Nicotine addiction is as prevalent with e-cigarettes as it is with traditional cigarettes. E-cigarettes produce little or no tar, carbon monoxide and metals compared to the high levels found in traditional cigarettes. This is why advocates of vaping argue that e-cigarettes are safe. Unfortunately, there is still very little evidence regarding the health impact of e-cigarettes, simply because e-cigarettes haven’t been around long enough to accurately asses long-term effects.
Cardiovascular toxicants that are present in traditional cigarettes such as formaldehyde, acetaldehyde, acetone, acrolein, and butanol are also found in e-cigarettes. These toxicants alone can increase cardiovascular disease (CVD) risk by negatively affecting blood pressure regulation, stimulating too much coagulation, and accelerating the formation of atherosclerotic lesions. Even nicotine heavily affects cardiovascular function. Vaping increases the heart rate and blood pressure just as much as conventional cigarettes.
Many e-cigarette liquids also have been found to contain diacetyl, a flavoring agent that has been linked to serious lung disease such as bronchiolitis obliterans. Most of these chemicals are considered safe when eaten in trace amounts, but inhalation is an entirely different form of consumption.
