Those who reported drinking alcohol during the preceding year were then asked to declare the number of alcoholic drinks they had consumed during the week prior to interview according to ‘measures’ of spirits, ‘glasses’ of wine or ‘pints’ of beer or cider. A conservative 8 g of alcohol is assumed per measure of spirits or glass of wine, and 16 g for each pint of beer or cider. Measurements were aggregated to derive the total grams of alcohol consumed during the week prior to interview among current drinkers.
