Except the data I presented suggests that any role of such advertising is very small and weak at best. Cultural norms do have a big influence on behavior. But if ads were the primary shapers of cultural norms of drinking consumption, then the data I presented would be the opposite of what it is.
The evidence suggests that both individual behavior and the culture norms of behavior are not the product of ads.
That's an odd way to put it. They drink because it has natural appeal to them. Perhaps some of them haven't stopped because it there are so few non-drinkers to socialize with. But that is only the case because the vast majority of people like it. Also, I suspect that most drinkers do know people who don't drink and have met people don't and had the chance to revise the social circles to be less alcohol focused, yet they choose not to. Also, most drinkers go through periods of non-drinking for various reasons from losing weight, to getting over an illness, to being too busy with responsibilities. So, they have experience with variation in drinking and its impact on their well being, yet continue to return to drinking. So, I think you are talking about a small minority of drinkers.
Drinking is such a pervasive and accepted part of almost every culture in the world that people accept it as a way of life.
Ok, granted, people like alcohol because it's a lot of fun. But almost the entirety of humanity in 2018 will go through their lives without a single person saying to them: 'you know, maybe you only like alcohol because you're addicted to it, and you'd probably be happier if you just stopped'.
Yes the normalization and culture exists because we put it there, but there is no reason why we can't make gains to change this culture, or if not, just make people more aware of what their own relationship with alcohol actually is, and what the real health effects are.
Yes, drinking is the pervasive norm in all free societies, but advertising has played little role in that normalization. In fact, that very pervasiveness of drinking in every culture where it is not prohibited is just what is predicted by the theory that ads have little to do with it, and it is a natural byproduct of human nature and to innate appeal of its consumption.
Cultural norms can arise from top-down social coercion or be a byproduct of most people being naturally drawn to that act or idea. The only cultures where drinking is not the norm are those with the highest top-down authoritarian coercion against it (e.g., Islamic and other conservatively religious cultures). When people are more free to choose to drink or not a "drinking culture" naturally arises out of each person finding it intrinsically appealing, and if most people are personally inclined to do something than that is the "norm" as a simple matter of statistical artifact, and is not something that was "created by us" any more than cats have created cultural norms whereby most cats like tuna.
Sure, there is a minority of people who don't intrinsically like to drink but do so because most others do. They might be happier if they stopped drinking. But even they are not obeying the norm because of advertising. Going with the norms is also human nature, so if most people also naturally enjoy drinking then the minority that don't will naturally go along with it, without needing propaganda to do so. If anything propaganda is needed to get people to go against their natural tendencies. So, if you want to get people who are drinking only because it's "normal" to stop drinking, then that's where propaganda would be most needed.
But I would caution against propaganda that (like most anti-drug propaganda) overplays the "addiction" angle. It doesn't help the sobriety cause to throw around that word without sound scientific biological basis (i.e,, one's body reacts negatively to the absence of the substance and the person feels ill when not using) .
Unless "addiction" is tautologically defined to simply mean doing it alot or enjoying it (which sadly it often is used that way), then most drinkers are not drinking b/c they are addicted, any moreso than most people who exercise are only doing it because they are "addicted". Heck, even many of the people with a real addiction to alcohol are drinking for other reasons and the addiction is just a byproduct that would keep them from quitting if they wanted to, which they don't.
