Three quarters of all alcohol consumed in Wales is drunk by less than a quarter of the adult population who are hazardous or harmful drinkers and spend up to £2,882 per year on booze, research has revealed.
A report looking into the potential impact of minimum unit pricing and taxation policies in Wales was published on Thursday by the Sheffield Alcohol Research Group at the University of Sheffield.
The publication, which found that the 3% of the population who are harmful drinkers, account for 27% of all alcohol consumed, comes after the Welsh Government announced a new Bill that, if agreed by the National Assembly, will introduce a minimum price for the sale of alcohol.
The Bill, which is designed to reduce hazardous and harmful drinking would make it an offence for alcohol to be supplied below that price.
Health Secretary, Vaughan Gething said: "People who drink alcohol at hazardous and harmful levels drink 75% of the alcohol consumed in Wales.
"The introduction of a minimum unit price would be effective in reducing alcohol consumption among these groups, as well as reducing the number of alcohol-related deaths and hospitalisations."
The availability of cheap, strong alcohol is estimated to lead to 50,000 alcohol-related hospital admissions a year, costing the Welsh NHS £120 million annually and, in 2015, there were 463 alcohol-related deaths in Wales.
The report reveals the population of Wales buys 50% of its alcohol for less than 55p per unit, 37% for less than 50p per unit and 27% for less than 45p per unit, with heavier drinkers being more likely to buy alcohol sold below these thresholds.
Mr Gething said: "The report shows the greatest impact of a minimum unit price would be on the most deprived harmful drinkers, while moderate drinkers would experience only small impacts on their alcohol consumption and spending.
"This is because moderate drinkers tend to buy alcohol which would be subject to little or no increase in price under the policy.
"If passed, this law will potentially save lives."
The research also shows harmful drinkers spend an average £2,882 a year on alcohol, or around £7.80 per day, compared to £1,209 for hazardous drinkers and £276 for moderate drinkers.
The Sheffield Alcohol Research Group, which was commissioned by the Welsh Government in June 2017 to update a 2014 appraisal of the likely impact of a range of minimum unit pricing policies, concluded a minimum unit price set at between 35p and 70p would be effective in reducing alcohol consumption among hazardous and, particularly, harmful drinkers.
