From Public Health Scotland today:

The introduction of MUP in Scotland on 1 May 2018 was associated with a net reduction in the total volume of pure alcohol sold, when controlling for sales in the best available geographical control area and adjusting for other factors.

Using our main model, we found MUP to be associated with a net reduction of 3.0% in total per-adult sales in the
three years following implementation; this was driven by a 3.6% reduction in sales through
the off-trade (Figure 1).

This net reduction reflects a 1.1% fall in alcohol sales in Scotland (1.3% in the off-trade) in contrast to a 2.4% increase in England & Wales (2.5% in the off-trade) over the same time period. No change to per-adult sales of pure alcohol through the on-trade was observed over the study period

MUP is, of course, one part of a wider strategy to reduce alcohol harm.

First: Sharp fall in alcohol-related hospital statistics

In 2020/21 the rate of alcohol-related hospital admissions to general acute hospitals was 614 per 100,000 populations and was 10% lower than the rate recorded during 2019/20 (681 per 100,000).

Second: NHS Scotland smashes drug and alcohol waiting times targets

Of the 8,202 referrals to community-based specialist drug and alcohol treatment services completed in this quarter [January to March 2022], 92% involved a wait of three weeks or less.

The target is 90%.
