@MauriceGSwanson @ATHRA_AU @MailOnline @PHE_uk 1/... Hello Maurice. I’m always interested in the basis and motivation for disputing ‘at least 95% less harmful’ as a basis for communicating relative risks of vaping Vs smoking. Let’s start with the basis.
@MauriceGSwanson @ATHRA_AU @MailOnline @PHE_uk 2/ The figure is (expressed as at likely to be less than 5% of the harm) was also the funding of @RCPLondon in #NicotineWithoutSmoke
@MauriceGSwanson @ATHRA_AU @MailOnline @PHE_uk @RCPLondon 3/ @theNASEM declined to put a number on it but found, on the available evidence (what else is there?) likely to be far less harmful, although more research is needed (when isn’t there?)

When the weaknesses have more weaknesses than the study they critique. Here’s a few:
1. The previous RCTs also found EC more effective, even though the devices were obsolete when the studies were published. The effect size was smaller because the devices weren’t as good.
2. The ‘highly selected group’ were smokers who want to quit. This is entirely normal for a stop smoking survey. Who else would you recruit? Non smokers or smokers who don’t want to quit?
