This!
Just cos its published in the Lancet, doesn't mean you take the report conclusion at face value. You don't look at it in isolation and fail to look at other reports on the same subject. You don't just completely ignore the methodology or fail to consider whether the report has significant flaws.
The likes of Ben Goldacre and Margaret McCartney have written extensively on the problems of 'cherry picking' from Big Pharma etc.
However the likes of Brand are doing EXACTLY the same thing.
They aren't doing something revolutionary or new. They are just repeating the flaws from a different perseptive rather than acting in a credible way as per the ways identified by the above mentioned to reduce the harms this is doing.
Honestly, its just spoonfeeding alternative sourced rubbish.
