Who said anything about a drinking problem? But ads that glorify and make drinking seem exotic/cool/whatever can normalize underage drinking, or any activity for that matter: maybe you're aware of the massive vaping craze among the young, partly as a result of viral social media that does that same thing. Don't act like media exposure can't have any impact on expectations, social norms, and the like. And take notice of the fact that in the 80s and 90s when awareness of this sort of advertising issue curtailed such advertising in traditional media, things like incidents of drunk driving and related accidents/deaths began their years-long decline.
