Listening to the Today programme this morning, I was interested to hear the Chief Medical Officer, Dame Sally Davies, defending the new guidelines on weekly limits for safe drinking. She was particularly keen to stress their basis in science and evidence. It reminded me of a passage in Betsy Thom’s book Dealing with Drink where she describes the somewhat arbitrary way in which the original guidelines were created, particularly the figures for weekly unit limits. It made me wonder whether the new figures were really as ‘scientifically’ based as she was suggesting.
She also didn’t answer the question put to her about why there are government warnings about safe alcohol consumption but not similar warnings about other common risky practices. The suggestion that this was a bit ‘unscientific’ didn’t go down well! Of course, the actual reason is political and socio-cultural but this is difficult for a Chief Medical Office to say when there is this attachment to the idea that health policy can and should be strictly and solely based on ‘scientific evidence’. As I have argued before, this is particularly short-sighted and unrealistic when it comes to drug and alcohol policy.
