He said he "HAD never heard of them." That doesn't mean he didn't research them after the news station contacted him for the interview. And the same thing he says that is found on e-cig websites is also found on many reduced harm sites, the AAPHP site and on the CASAA site. Considering he also followed up with accurate info about the FDA stance, he obviously did research, because you won't find that on most ecig sites. He was also familiar with the fact that some don't look like regular cigarettes. He also said he read e-cig blogs. To me, that makes it clear that he researched beyond stock e-cig web sites.
He also says "there is a lot of anecdotal evidence out there, but it just needs more study." So, he didn't exactly recommend that people run out and buy them to quit smoking. He touted why they would be better than smoking and cautioned that there hasn't been a lot of research, so I doubt he'd get in trouble from that.
