One of the under-reported findings from surveys of drinking during lockdown is in the detail of @AlcoholChangeUK survey.

While 22% drank on fewer days and 21% on more days, the figures on amount consumed per day were less balanced, 42% drunk less and only 13% drunk more.

If we combine the changes in frequency and quantity of consumption during lockdown from @AlcoholChangeUK's survey:
40% are definitely drinking less
21% are definitely drinking more
36% are drinking the same
3% are unclear (e.g. smaller amounts more often)

The usual caveats about alcohol consumption being difficult to measure apply but the continuing narrative that people are generally drinking more during lockdown needs scrutinising. There is almost certainly more home-drinking, but anything else is dubious.

What is perhaps more important is WHO is drinking more. The detail of several surveys suggests vulnerable groups - those furloughed, the long-term unemployed, people who are lonely or lack social support, and those with mental health problems - may have increased their drinking.

These are all groups we would be at elevated risk for alcohol problems in normal times, so we should be particularly concerned about them now.
