I thought the piece was a bit sensationalist, but the summing up back in the studio at the end was pretty balanced (which surprised me).
It's just a pity about that emphasis on whether vaping is "totally safe", rather than focusing primarily on the harm reduction side, especially seeing as the figures quoted at the end were that 52% of vapers are ex-smokers (so have reduced the amount of harm they are doing to themselves by at least 95%), 45% are dual fuelling (and in the studio they assumed this meant that they are trying to give up smoking using vaping) and only 3% of vapers have never smoked.
