article By John Egan and David H. BrownThe cost of smoking tobacco products in the United States has increased in recent years, as smokers are increasingly trying to reduce their risk of heart disease, diabetes and other diseases.
Now a new study has found that people who smoke cigarettes in addition to e-cigarettes may have an increased chance of lowering their risk for smoking-related diseases.
Researchers at the University of Pittsburgh’s School of Public Health looked at a cohort of 3,000 people over 20 years who smoked at least one cigarette daily.
Those who smoked e-cigarette liquids had a 40 percent lower risk of developing coronary heart disease than those who did not.
That’s because e-liquid is made of a tobacco-derived material called glycerol, which has similar chemical properties to tobacco.
The researchers noted that people with a history of smoking e-cigs may have a lower risk for developing cardiovascular disease.
However, the study does not directly link e-cig use with coronary heart risk.
Instead, they noted that the risk of death was reduced by nearly half among people who never smoked cigarettes and by nearly a quarter among people in the e-juice group.
“Our findings suggest that, in contrast to cigarette smoking, e-smoking may have more of an effect on the development of cardiovascular disease than cigarette smoking,” said lead author Emily B. Gaffney, a professor of public health and public health policy at Penn State University.
“For example, there may be a lower likelihood of developing cardiovascular events with e-vapor, compared to smoking.”
The researchers noted there were limitations to the study, however.
For one, there were few cases of cardiovascular death in the study population, which could limit the overall effect of the findings.
The authors of the new study noted that while the study found a reduction in coronary heart death among e-junkies, the findings should not be used to discourage e-smokers from using e-liquids.
“While the data are intriguing, they cannot be used as a justification for e-snus, which is a tobacco product with a relatively high rate of cardiovascular harm,” they wrote.
The researchers also cautioned against drawing too many conclusions about the long-term health effects of e-tobacco use.
“Our findings do not necessarily indicate that e-waste products are an effective substitute for tobacco-free products,” they said.
“This is an important caveat because tobacco-based e-fame and tobacco-associated diseases are both serious and costly.
The cost of e cigarettes is also substantial.”
