We found that if there was more advertising in a market there was more youth drinking.

People have been delaying doing anything because they felt the research wasn't there. This makes it clear that advertising does make a difference.

The results also contradict claims that advertising is unrelated to youth drinking amounts: that advertising at best causes brand switching, only affects those older than the legal drinking age or is effectively countered by current educational efforts.

Alcohol advertising was a contributing factor to youth drinking quantities over time.
