Binge drinking is definitely up among women. It seems to be more common for kids to have more drinking parties in high school - maybe access is easier?
It also seems to be harder to have a drink at a function and so girls seem to feel the need to drink a whole bunch in the hopes of keeping their buzz till the party which is what leads to incidents like this.
We did have problems 20 years ago when we would show up for a party and another chapter had the ballroom across the hall. They would all be sick in the bathroom so their dates would come over to our party. So if you cant have fun without getting smashed - you probably need to at least work on your conversationskills
