Supermarkets have long been criticised for fuelling alcohol addiction by offering cut-price drinks and special offers.
But research from The Grocer magazine has revealed that fewer supermarkets are implementing drink promotions, which is good news for those in need of alcohol rehabilitation treatment.
Such a programme of therapy can provide the physical and psychological support a person needs to combat their alcohol addiction, although to remain healthy and able to lead a normal life, patients must not return to alcohol - even in moderate amounts.
This is because their body is likely to respond to drink as it did before receiving alcohol addiction therapy - which could result in cravings or withdrawal symptoms.
According to The Grocer, the number of deals on alcohol in January made up less than a quarter (22 per cent) of all promotions, a figure that compares favourably with the 26 per cent recorded last year.
Charity Alcohol Concern has welcomed the finding. Don Shenker, its chief executive, said it is a "step in the right direction", although recommended that the government be braver if it really wants to tackle alcohol addiction.
"It needs to introduce a minimum price for alcohol," he suggested. "This will stop supermarket low-cost selling as well as deep discounts."
