The study published on Respiratory Research used calf lung surfactant extract and mimicked lung mechanics, while measuring its surface tension. The results indicated that regardless of its flavoring, e-cigarette vapor did not affect the ability of surfactant to reduce surface tension. In contrast, conventional cigarettes significantly inhibited the ability of surfactant to reduce surface tension upon compression.
“While both e-cigarette vapor and conventional cigarette smoke affect surfactant lateral structure, only cigarette smoke disrupts surfactant interfacial properties,” concluded the study authors, adding, “The surfactant inhibitory compound in conventional cigarettes is tar, which is a product of burning and is thus absent in e-cigarette vapor.”

Duh! Of course it is! Our government even encourages smokers to vape. I made the switch between smoking a vaping two years ago and now I’m trying to lessen the nicotine intake and initially stop entirely. It’s not easy though…I really like the juices… I’m currently vaping the ones by Vapour2, mainly the coffee and vanilla are great!
