I have a brother who recently turned 21. He has been drinking more and more heavily for the past year or so, and it has reached the point where there is no doubt in my mind that he is an addict. He drinks to the point of blacking out multiple times a week and has had multiple run-ins with the police. He recently passed out in the driveway, and I almost hit him with my car when I got home late. My family seems to think that this is normal behavior for a man his age, and they are all burying their heads in the sand. I am worried that it will take him getting seriously hurt before anyone else sees how much of a problem this is. Any suggestions or advice would be greatly appreciated.
