Background and Aims: The Scottish Government introduced minimum unit pricing (MUP) for alcohol on 1 May 2018. This means retailers in Scotland cannot sell alcohol to consumers for less than £0.50 per unit (1 UK unit = 8 g ethanol). The Government intended the policy to increase the price of cheap alcohol, cut alcohol consumption overall and particularly among those drinking at hazardous or harmful levels, and ultimately reduce alcohol‐related harm. This paper aims to summarise and assess the evidence to date evaluating the impact of MUP on alcohol consumption and related behaviours in Scotland. Argument: Evidence from analyses of population‐level sales data suggest, all else being equal, MUP reduced the volume of alcohol sold in Scotland by ~ 3.0% to 3.5%, with the largest reductions affecting cider and spirits sales. Analyses of two time series datasets on household‐level alcohol purchasing and individual‐level alcohol consumption suggest reductions in purchasing and consumption among those drinking at hazardous and harmful levels, but offer conflicting results for those drinking at the most harmful levels. These subgroup analyses are methodologically robust, but the underlying datasets have important limitations as they rely on non‐random sampling strategies. Further studies identified no clear evidence of reduced alcohol consumption among those with alcohol dependence or those presenting to emergency departments and sexual health clinics, some evidence of increased financial strain among people with dependence and no evidence of wider negative outcomes arising from changes in alcohol consumption behaviours. Conclusions: Minimum unit pricing for alcohol in Scotland has led to reduced consumption, including among heavier drinkers. However, there is uncertainty regarding its impact on those at greatest risk and some limited evidence of negative outcomes, specifically financial strain, among people with alcohol dependence.

Background and Aims: On 1 May 2018, Scotland became the first country in the world to introduce minimum unit pricing (MUP), a strength‐based floor price below which alcohol cannot be sold, across all alcoholic beverages. The legislation contains a sunset clause meaning a comprehensive mixed‐methods evaluation of its impact across a range of outcomes will inform whether it will continue beyond its sixth year. In this study, we assessed the impact of MUP on off‐trade alcohol sales (as a proxy for consumption) after its first year. Design, Setting and Participants: Controlled interrupted time–series regression was used to assess the impact of MUP on alcohol sales among off‐trade retailers in Scotland in the year after it was introduced, with England and Wales (EW) being the control group. In adjusted analyses, we included household disposable income, on‐trade alcohol sales and substitution between beverage categories as covariates. Measurements Weekly data on the volume of pure alcohol sold by off‐trade retailers in Scotland and EW between January 2013 and May 2019, expressed as litres of pure alcohol per adult. Findings The introduction of MUP in Scotland was associated with a 3.5% [95% confidence interval (CI) = 2.2–4.9%] reduction in off‐trade alcohol sales per adult after adjustment for the best available geographical control, disposable income and substitution. In unadjusted analysis, the introduction of MUP was associated with a 2.0% (95% CI = 0.4–3.6%) reduction in off‐trade alcohol sales per adult in Scotland. In EW, there was a 2.4% (95% CI = 0.8–4.0%) increase during the same time‐period. The reduction in off‐trade alcohol sales in Scotland was driven by reduced sales of spirits, cider and perry beverage categories. Conclusion: The implementation of minimum unit pricing for alcohol in Scotland in 2018 appears to have been associated with a reduction in off‐trade alcohol sales after its first year.

Aims: To investigate whether the introduction of minimum unit pricing (MUP) in Scotland on 1 May 2018 was reflected in changes in the likelihood of alcohol‐related queries submitted to an internet search engine, and in particular whether there was any evidence of increased interest in purchasing of alcohol from outside Scotland. Design Observational study in which individual queries to the internet Bing search engine for 2018 in Scotland and England were captured and analysed. Fluctuations over time in the likelihood of specific topic searches were examined. The patterns seen in Scotland were contrasted with those in England. Setting: Scotland and England. Participants: People who used the Bing search engine during 2018. Measurements Numbers of daily queries submitted to Bing in 2018 on eight alcohol‐related topics expressed as a proportion of queries on that day on any topic. These daily likelihoods were smoothed using a 14‐day moving average for Scotland and England separately. Findings There were substantial peaks in queries about MUP itself, cheap sources of alcohol and online alcohol outlets at the time of introduction of MUP in May 2018 in Scotland, but not England. These were relatively short‐lived. Queries related to intoxication and alcohol problems did not show a MUP peak, but were appreciably higher in Scotland than in England throughout 2018. Conclusions: Analysis of internet search engine queries appears to show that a fraction of people in Scotland may have considered circumventing minimum unit pricing in 2018 by looking for on‐line alcohol retailers. The overall higher levels of queries related to alcohol problems in Scotland compared with England mirrors the corresponding differences in alcohol consumption and harms between the countries.

Background and aims: Within the context of Scotland's policy change to implement a minimum unit price (MUP) per unit of alcohol sold in licensed premises, this study used an N‐of‐1 design to assess between‐person differences in the psychological and social factors associated with daily alcohol consumption. Design and setting: A mixed‐methods approach combined N‐of‐1 observational studies, comprising daily surveys followed by qualitative social network interviews (not reported here). Peer researchers with lived experience of substance use were involved in the study design and fieldwork was conducted in towns and rural areas in the East of Scotland. Participants/cases: Twenty‐five adults with current or recent history of alcohol dependence recruited for three 12‐week waves: 11 in wave 1 (pre‐MUP), 11 in wave 2 (pre‐ and post‐MUP) and three in wave 3 (post MUP). Measurements Gender, age, alcohol and other drug use history. Daily surveys for 12 weeks captured information about factors in the last 24 hours, e.g. amount and type of alcohol consumed, stress, social contact. Findings Each participant was in the daily survey for a mean of 64 days [standard deviation (SD) = 42; median = 59], with a response rate of 48%; 15 participants provided sufficient data for analysis. Factors related to daily alcohol consumption differed between individuals. Models suggested that some individuals with high initial consumption reduced drinking after MUP, but explanatory factors differed, e.g. changing motivation was important for some, while alcohol availability was important for others. Conclusions: Adapting N‐of‐1 methods for an observational study uncovered differences in alcohol consumption change before and after minimum unit pricing implementation in Scotland, evidence of individual differences in the factors relating to alcohol consumption patterns and some evidence that post‐MUP consumption changes may be related to changing psychosocial factors.
