"safest level of drinking is none" - new study

I guess a litmus test would be to ask oneself if they, from tomorrow, could never consume alcohol again, period, would they have a problem with that? If answering honestly if they could easily forego the intermittent glass of shiraz, that it wouldn't bother them in the slightest then they have no problem. If it would induce some kind of panic or anxiety then you'd have to question your drinking.

bit of a leap from "the safest level of drinking is none" to "heavy alcohol use"

Personally I don't doubt the research. I think you can only accept risk when you are informed so it is always better to be informed. Nothing wrong with undertaking activities that have increased risk of illness or reduced health.

the paper did not report any absolute risks, meaning that readers couldn’t tell how dangerous drinking alcohol really was for them. Fortunately this extraordinarily lax review process was countered by the Lancet press office who asked for absolute risk estimates from the authors. This is truly excellent practice for which the press office deserve sincere congratulations. Especially as they also headed the press release with “Peer-reviewed / Observational study / People”, an example of the new Science Media Centre/Academy of Medical Sciences guidelines for headlining press releases.

The press release reported that

Specifically, comparing no drinks with one drink a day the risk of developing one of the 23 alcohol-related health problems was 0.5% higher — meaning 914 in 100,000 15–95 year olds would develop a condition in one year if they did not drink, but 918 people in 100,000 who drank one alcoholic drink a day would develop an alcohol-related health problem in a year.

This increased to 7% in people who drank two drinks a day (for one year, 977 people in 100,000 who drank two alcoholic drinks a day would develop an alcohol-related health problem) and 37% in people who drank five drinks every day (for one year, 1252 people in 100,000 who drank five alcoholic drinks a day would develop an alcohol-related health problem).

So the information is now all there, but what does it actually mean for moderate drinkers?

Let’s consider one drink a day (10g, 1.25 UK units) compared to none, for which the authors estimated an extra 4 (918–914) in 100,000 people would experience a (serious) alcohol-related condition.

That means, to experience one extra problem, 25,000 people need to drink 10g alcohol a day for a year, that’s 3,650g a year each.

To put this in perspective, a standard 70cl bottle of gin contains 224 g of alcohol, so 3,650g a year is equivalent to around 16 bottles of gin per person. That’s a total of 400,000 bottles of gin among 25,000 people, being associated with one extra health problem. Which indicates a rather low level of harm in these occasional drinkers.

Next look at 2 drinks a day, that’s 20g, or 2.5 units, slightly above the current UK guidelines of 14 units a week for both men and women.

In this case, compared to non-drinkers an extra 63 (977–914) in 100,000 people experience a health problem each year. That means, to experience one extra problem, 1,600 people need to drink 20g alcohol a day for a year, in which case we would expect 16 instead of 15 problems between them. That’s 7.3 kg a year each, equivalent to around 32 bottles of gin per person. So a total of 50,000 bottles of gin among these 1,600 people is associated with one extra health problem. Which still indicates a very low level of harm in drinkers drinking just more than the UK guidelines.

This analysis supports the current UK guidelines as being low-risk, but perhaps would better be described as ‘very low-risk’.

Is this an argument for abstention?

The paper argues that their conclusions should lead public health bodies “to consider recommendations for abstention”.

But claiming there is no ‘safe’ level does not seem an argument for abstention. There is no safe level of driving, but government do not recommend that people avoid driving.

Come to think of it, there is no safe level of living, but nobody would recommend abstention.
