<Li> According to Alcohol and You Northern Ireland resource website, "Most alcopops contain 1.1--1.5 units per bottle . For example, a normal 275 ml bottle of WKD contains 1.1 units, whereas Bacardi Breezer and Smirnoff Ice both contain 1.5 units of alcohol ." </Li> <P> On average, it takes about one hour for the body to metabolise (break down) one unit of alcohol . However, this will vary with body weight, sex, age, personal metabolic rate, recent food intake, the type and strength of the alcohol, and medications taken . Alcohol may be metabolised more slowly if liver function is impaired . </P> <P> From 1992 to 1995, the UK government advised that men should drink no more than 21 units per week, and women no more than 14 . (The difference between the sexes was due to the typically lower weight and water - to - body - mass ratio of women .) The Times reported in October 2007 that these limits had been "plucked out of the air" and had no scientific basis . </P> <P> This was changed after a government study showed that many people were in effect "saving up" their units and using them at the end of the week, a phenomenon referred to as binge drinking . Since 1995 the advice was that regular consumption of 3--4 units a day for men, or 2--3 units a day for women, would not pose significant health risks, but that consistently drinking four or more units a day (men), or three or more units a day (women), is not advisable . </P>
