Alcohol is the third leading preventable cause of cancer in the United States, following tobacco and obesity. While 90 percent of Americans know tobacco causes cancer, fewer than half realize alcohol does as well. Like tobacco warnings, alcohol warning labels would help consumers make more informed health choices.
I’d much rather force manufacturers to use plain packaging (white label + black text in a standard font). Make it look as boring as possible with large warnings. Colors and branding have a very significant effect on sales - why else would labels have designs?
It will certainly also make it seem less normalized for children. Right now alcohol packaging is hardly distinct from some soft drinks.
