where did the term proof for alcohol come from
Alcohol proof The term proof dates back to 16th century England, when spirits were taxed at different rates depending on their alcohol content. Spirits were tested by soaking a pellet of gunpowder in them. If the gunpowder could still burn, the spirits were rated above proof and taxed at a higher rate.[1] As gunpowder would not burn if soaked in rum that contained less than 57.15% ABV, rum that contained this percentage of alcohol was defined as having 100 degrees proof.[2] The gunpowder test was officially replaced by a specific-gravity test in 1816.[1]
Alcohol Use Disorders Identification Test The Alcohol Use Disorders Identification Test (AUDIT) is a ten-question test developed by a World Health Organization-sponsored collaborative project to determine if a person may be at risk for alcohol abuse problems.[1][2] The test was designed to be used internationally, and was validated in a study drawing patients from six countries. Several research studies have found that the AUDIT screening tool is a reliable and valid measure in identifying alcohol abuse problem behaviors and it has been found to be a valid indicator for severity of alcohol dependence.[3][4] There is some evidence that the AUDIT works in adolescents and young adults; it appears less accurate in older adults. It appears well-suited for use with college students, and also with women and members of minority groups.[5]
