Since international tobacco companies [3] have also owned alcoholic beverage companies, tobacco documents yield information about the inner workings of the liquor industry. Researchers studying tobacco documents have found that liquor companies are terrified of going down the same route as the tobacco industry. An article published in the Australasian Medical Journal found that the top concerns of the international alcohol industry were: alcohol becoming a major public health issue and the focus of negative attention, like tobacco; tax increases; mandatory health warnings on alcoholic beverages; regulations on advertising and sponsorship; tougher policing for drunk drivers and lowered blood alcohol limits; litigation; well-funded, independently-run mass media public education programs about alcohol; people viewing alcohol as the cause of problems for the community rather than just "addicted individuals"; and raising the legal drinking age. The industry tries to play down its role in contributing to alcohol problems and opposes the lowering of blood alcohol levels for drunk driving and raising the legal age of drinking.
