This popped up tonight in the New England Journal of Medicine which is one of the leading medical journals in the world and highly respected in pretty much all medical fields. In a nutshell, people stopped smoking twice as much with e cigs than NRT. It's the first real study to address this head on. There are some accompanying editorials that still express concern on flavorings, appeal to minors, and long term use, but it's still a big deal. Already written up in the NY Times even though it literally came out tonight.

This is a pretty important event. It's not without caution, and it doesn't settle the flavoring issues, nicotine as a gateway drug (I think it's settled but not everyone agrees) and long term use issues, but it's a lot tougher to dispute the role it actually plays in combustible tobacco cessation which up until now lacked anything that points right at the issue.
