How much of that is due directly to the alcohol and how much is due to good old-fashioned human stupidity, slightly enhanced? The issue with this stat is that someone hurts/kills themselves or someone else, they had alcohol in their system, ergo it's an "alcohol-related incident". The problem with this line of reasoning should be obvious.
