A new study published yesterday in the journal BMC Cardiovascular Disorders reports that unlike real cigarettes, electronic cigarettes do not adversely affect acute heart function.

(See: Dutra LM, Glantz SA. Electronic cigarettes and conventional cigarette use: a cross-sectional study. Published online March 6, 2014. JAMA Pediatr. doi:10.1001/jamapediatrics.2013.5488.)

After one year follow-up, both the ex-smokers and dual users experienced a significant improvement in asthma symptoms and lung function, especially small airways obstruction. Although the improvements in lung function were small, the improvements in asthma symptoms were clinically relevant.

The saddest part of the story is that while Councilman Constantinides is so concerned about youth "addiction" that he is willing to ban electronic cigarettes, he expressed no similar desire to ban the real ones. That's not public health leadership. It's political cowardice, and hypocrisy.
