Doncaster Council is joining other organisations across the country to highlight problem drinking during Alcohol Awareness Week, which runs until Sunday.
Official figures state Doncaster has an estimated 5,643 dependent drinkers with 11 per cent of those in treatment.
Guidelines state women should not exceed two to three units per day (a large glass of wine) and men three to four units per day (a pint of premium lager).
Dr Tony Baxter, Doncaster Council Director of Public Health, said: “The risk isn’t just for heavy drinkers. Regularly drinking over this guideline can triple your risk of mouth and throat cancer and double your risk of heart disease.
