Using alcohol sales data, which are considered the best available for assessing the impact of policy on population levels of consumption, our study in collaboration with the University of Glasgow found that the introduction of the Alcohol Act (which included the discount ban) in October 2011 was associated with a 2.6 per cent decrease in the amount of alcohol sold per adult in Scotland.
This was largely driven by a 4 per cent decline in wine sales.
As similar declines were not observed in England and Wales where the Alcohol Act does not apply, and because we took into account factors such as changes in income and alcohol prices, we are confident that banning multi-buy promotions reduced the amount of alcohol sold in Scotland.
