I don't actually think that advertising is at all to blame for the misuse of alcohol. Similar adverts are shown in countries with a far better track record. It's a culture and it has been there for generations.
People look at the per capita consumption in 1960 and how much larger it is today and conclude that the average person is drinking a lot more, but I don't think that is the case. In 1960, most women were either abstainers, or very occasional drinkers (Christmas, weddings, etc.). My contention is that much of the rise in per capita consumption since 1960 is due to Irish women taking on the drinking culture Irish men already had.
I think there are two kinds of alcohol related harm and they need to be handled in different ways. There is acute harm, where people get drunk and harm themselves or others, or simply make a nuisance of themselves and there is chronic harm, where people drink too much on a regular basis and end up with an alcohol related illness.
The first is caused by drunkenness. This is binge drinking. It is not defined by a certain number of units in a sitting, it is characterised by drinking until you are out of control. The second may be caused by the first, or a less dramatic heavy drinking over many years.
Acute alcohol related harm happens because it is considered acceptable in our society to drink until you are out of control. The only way to reduce this significantly and long term is to change the culture. Social pressure is very powerful. If your friends laugh and accept you being drunk, or spend their weekends in pursuit of drunkenness, then it is ok, even encouraged, for you to do it. If your peers disprove and are embarrassed by your drunken antics you will learn to control your intake fairly sharpish.
If you have any suggestions on how to achieve this cultural change I would genuinely welcome your input. I think it can be done. The attitude to drink driving has changed in a remarkably short time and I find that encouraging.
There are many reasons for chronic alcohol related harm and I think the only way a civilised society should deal with it is by offering help if it is wanted, but also accepting that freedom means the right to make self destructive choices too.
