The Marini study demonstrates that electronic cigarettes do lead to a reduction in exhaled nitric oxide, which suggests that they have a mild respiratory irritant effect and induce some inflammation in the airways.

Last week I wrote about my blunders and tribulations of making my own E-Juice. It had its ups and downs but after many revisions I had something that I could vape without instantly regretting it. I wanted to see how the professional E-Juice makers were doing it on a large scale instead.

Regrettably not many vendors wanted to reveal their E-Juice secrets to me, but fortunately I did have two vendors (who wanted to remain anonymous) willing to share their secrets and their E-Juice making process with everyone who wants to know about it.
