As you can see in these image from their website, a Cigavette looks like any other electronic cigarette. They have all the same components and look the same. But the key difference, according to Cigavette, is the “smart chip” that controls the heating element and LED.

In fact, this is precisely what Trueba et al. demonstrated in a of changes in exhaled nitric oxide levels in 41 healthy college students.

There is little question that electronic cigarettes are much safer than tobacco cigarettes (even Glantz himself admits that). And further, there is little question that the most important piece of information consumers need in deciding whether to continue to smoke real cigarettes or switch to the fake ones is that the fake ones don't contain or burn tobacco and are therefore much safer than the real tobacco cigarettes.

Thus, the authors readily acknowledge that it is impossible from this study to determine whether or not e-cigarettes lead to smoking or whether smoking leads to e-cigarette experimentation.
