If you’ve decided to quit smoking using ecigs or if you’ve decided to switch from regular cigarettes to e-cigarettes, some good news has come out of recent research. While e-cigs probably aren’t 100% safe, they are possibly less harmful to your health than conventional smoking.
In a report released in August researchers from the Athens- based Onassis Cardiac Surgery Center said e-cigarettes show no connection to heart disease.
Investigators examined the heart activity of 20 young daily smokers after one ordinary cigarette as compared to 22 people who smoked a vapor cigarette for 7 minutes. Tobacco smokers showed “significant” disruptions of functions such as heartbeats or blood pressure; however, the effect of e-cigarettes on the heart was minimal.
The researchers noted that previous studies have found that the electronic devices would have to be smoked daily for four to 12 months to attain the level of carcinogens that are present in a single tobacco cigarette.
In a separate study conducted at the University of Athens, researchers found that smoking an ecig caused an immediate increase in airway resistance, lasting for 10 minutes and making it harder for participants to breathe.
The researchers used a lung function test to observe airway resistance in 32 participants who used an e-cigarette for 10 minutes. Among the healthy subjects who had never smoked, airway resistance rose to an average 206 percent from 182 percent; among smokers with normal lung function, the reading rose to an average 220 percent from 176 percent.
According to Christina Gratziou, one of the study authors, more research is needed to understand whether the effect on the lungs is long-lasting.
About 2.5 million people use e-cigarettes in the U.S., according to an estimate by the Tobacco Vapor Electronic Cigarette Association. The World Health Organization has asked that more clinical studies be conducted to determine whether e-cigarettes are safe and effective because they currently are not regulated.
