I can't believe how mainstream drinking is. As was pointed out alcohol is just one of many different behaviors that can be destructive. There is a big difference in terms of it being socially encouraged.
In the 20 years I worked corporate jobs there were always a string of 'team building' type of events. Either holiday get togethers, celebratory dinners, big conventions, etc. Always, at the end of the business day when the food was served it was expected that everyone start drinking. Those on the team who were the most out of control were glorified. The next day people would show off pictures and relive who sang the worst karaoke or who was slurring and falling down the most.
I don't enjoy drinking more than one drink and always felt extremely out of place. People would heckle me and plead with me to just go with it and have some fun. You know those videos about peer pressure in middle school where everyone rolls their eyes and says "It doesn't happen like that, people don't just say 'C'mon man, everyone's doing it!'"? Well, that's exactly how it is.
You don't see this with any other addiction. Sure, people get together and go gamble, or do different drugs, or whatever. But alcohol is the one that is backed by every family gettogether, every corporate event, every major sporting event (live or when friends watch the game), to every barbeque.
I have no problem with a drink now and then and think it's fine to loosen up every now and again and celebrate our lives together. But for many people it stopped being celebratory a long time ago. And what's disappointing is it feels like society expects it to be that way.
