Thank you for doing this IAMA!

What are the chances of cancer with the blu eCig compared to a normal cigarette by a major tobacco brand like Camel or Morlboro and are they FDA approved?

Edit:(I ask because i'm interested in switching to these, specifically blu as i've seen a lot about it.)

A lot of study's have shown that most E-Cigs that claim they contain no nicotine, a specific value of nicotine like 20mg or whatever are wrong. For example, says tehre is no nicotine but found 2mg of it, or says 20mg but it's never 20. Sometimes more or sometimes less. Thoughts? How accurate is blu compared to others E-Cigs?

Do you happen to be at the World Food Prize in Des Moines, IA?
