:Thanks . I've seen that video, and kept up with the ecig science. But I've abandoned the wiki articles on the topic because the dogmatic twits in the MED project can't be convinced by evidence & argument. As long as their "infallible" Pharma-funded WHO and NGO front groups pursue anti-vaping lunacy I don't think there's any way to improve these articles. If you haven't seen these, I highly recommend the reading , , .
