Education is good. If nothing else it will help those who are not alcoholic deal better with those who become alcoholic. But it will NOT stop anyone from becoming an alcoholic. You could have educated me fully on the dangers of alcoholism, and I can tell you it would have made no difference. I was 12 the first time I drank alcohol and got drunk, and I absolutely fell IN LOVE with the feeling. Nothing would have stopped me from immediately wanting to do it again. And again, and again. My brain was genetically preprogrammed to respond to alcohol with a feeling of intense euphoria. And that it did. To me, at that time, it was the most amazing and wonderful feeling I'd ever felt. And nothing was going to stop me from feeling that, again.
Your Councillor was right. Most alcoholics will die in their addiction. As will most drug addicts. And once they have that initial experience with it, nothing will dissuade them from wanting more of it. Education up front may help, but I wouldn't count on it helping, much. Like I said, it will help the people who care about the addict/alcoholic, more. As it may help them to understand that addiction is a kind of insanity. And that the addict can't see it for what it really is. And even when they do, they can't stop engaging in their obsession with it.
If you really want to try and understand this better, read the book Alcoholic Anonymous, and go to some open AA meetings. Talk with those who know this illness first hand. Listen to their stories. You will quickly discover what a difficult disease it is to try and recover from. And that self-will, alone, will not get it done. But I do greatly commend your desire to help.
