I see maybe 2% of the article as factual / favorable and 98% as "things an ANTZ might say."
This notion that eCigs are not benign and not (100%) safe is just ridiculous fodder. You can (accurately) say the same thing about water. It is not 100% safe. People have OD'd from drinking water and have drowned in it. Therefore not entirely safe. But if we were to compare drinking water, say at 5 cups daily compared to drinking same amount of whiskey, suddenly water looks like a far better choice. But that still doesn't make it 100% safe.
And since you can do this with water, then there is literally nothing around that is inherently benign and thus when they write these articles they are always (and I mean always) coming up with the idea that says: because it is not 100% safe, that's why we need onerous regulations on them to ensure that people are not in danger from just anyone distributing this to anyone.
When in actual reality, the regulations could plausibly do more damage, both to individuals and to society / public health. But because that last part is debatable (and counter intuitive), it is downplayed to oblivion, until regs get so far out of control that a black market exists, regardless of how legal the product is. Smoking would be prime example of what I am getting at.
