Sorry I'm lost... since theres no harm identified from ecigs in the past 10 years (which is long term...in fact twice as long as would be required) since they were first sold... and since there are no patients in any hospitals complaining of ecig induced diseases. Since in all that time anyone with an axe to grind has thrown literally billions of dollars desperately trying to find problems with vaporisers including putting voltages of 100 or 200 volts through them (the normal voltage is just 5 volts)  and then claiming they produced toxins at that voltage (what a surprise)  ... in all that time, with all of those studies nobody has identified a single thing that poses a public health risk... nothing whatsoever.... not so much as a molecule out of place...

At this point its truly pathetic looking at folks making fools of themselves... nobody is falling for it any more. If anything its like looking at idiots claiming they invented the perpetual motion machine.

Anyway rant over.... the above being the case then what does it matter if there were 17 thousand tweets trying to either sell them (or more likely simply running a scam to get money) from folks? Thats whos's sending out the tweets BTW...scam artists who are not selling ecigs... they are just looking for your credit card number.

I'd hazard a guess in the same period there were several million commercial tweets trying to sell class A drugs (again more scams) and probably a billion tweets or more selling all sorts of other stuff...

This is pointless science....and to me demonstrates that often times research money is spent fruitlessly. This is a reason to question the motives of the researchers...
