I read the clip attached but didn't see anything about a "study" (i.e. an article published in a peer reviewed scientific journal). Just the opinion of a guy who defends tobacco companies in their many lawsuits and vague references by a "journalist".

I'd love to see an actual study somewhere, even if it is true and not an article planted by the tobacco company, I'd still love to see the data.
