Great video!
I've been able to find some studies in which Professor Etter participates on Google Scholar and even to download a few ones with my University login. Unfortunately, 2 out of the 3 files I've been able to download so far are 1 or 2 pages long (but interestingly, one of them is a comment about an other study I found about an hour before viewing this
thread... Coincidence?!

)
The most interesting one is named "Analysis of refill liquids for electronic cigarettes" but i have not read it yet (just found it few minutes ago!)
Also, Google Scholar gave me this page as a result while I was searching " Jean-François Etter " :
No Sisyphean Task: How the FDA Can Regulate Electronic Cigarettes by Jordan Paradise :: SSRN
It looks like it's from an other person (Jordan Paradise) and the abstract of the article seems interesting, but I haven't been able to access the full 40 pages document with my University login. Maybe someone studying in a US University could access it (I'm from Qc, Canada)? Here's the information for anyone who wants to try to find it :

Sorry for the semi incomplete bibliography, semester is finished
I'm really considering doing a research on e-cigs as a University project the second I have the opportunity to do so. Saddly, I had a great opportunity last semester and didn't thought about doing it on that subject, but my subject brings me to read a bit on how some governments have come to prohibit not-so-hasardeous intoxicants while promoting some a-bit-more-hasardous ones and I can see that the same process is being applied to e-cigs, in USA just like here in Canada.
