Rofl, it'd take a little know how to make your own thc liquid to be vaporized by the thing. But, talk about personal vaporizer as opposed to this thing.

Did i mention that the container holding the electric cigarette is also the charger, charges up through usb, and is about the same size as a pack of smokes

Mine didn't come with a wall charger, but i use my blackberry charger for it.
These products are occasionally banned in non smoking areas. Now while you can puff on these in non smoking areas because it's not smoke, no risk of second hand, and it's not toxic people still think that seeing is believing.
The number one thing behind these electronic cigarettes is confusion to the ill knowledged. People see the smoking habit continue without the smoke, they automatically assume this to be bad because anything associated with smoking is bad (in this case the only thing associated with smoking would be the physical of habit of still puffing on something that's like a cigarette but isn't).
The number two thing is that a lot of people are retards and think that seeing is believing. They see someone smoking on what doesn't really look like a cigarette, but they say all this vapor coming off of it that looks like smoke, to them hence that person is still smoking with actual smoke. It's very hard to convince these people otherwise even if you break down the electric cigarette in front of them. If an asthmatic person tries to tell me i'm bothering them with this, i'm going to tell them to piss off i know this wont bother them (in fact the ingredients in the liquid aside from the nicotine is found in inhalor medication anyway).
These are the reasons why people go ape **** about the electronic cigarette. Me, i'm just going to be discreet about it. I'm just going to puff on this thing in smoking designated areas, and smoke it indoors where i live or when no ones around. The people who get these banned in non smoking areas are the retards who whip them out without thinking at like a family restaurant or something and start puffing away and everyone in the food establishment goes ape ****. This is why i'm discreet about it

As far as i know for the week of research on these, the fda seems to just be spreading fud not backing up their claims, and these haven't in anyway been negatory for people's health. The fda is actually recommending to smoke tobacco instead of using the electronic cigarette.
