You can say I'm in denial all you want.. but if the alcoholism label was helpful then the AA treatment model would be more successful. The 12 step movement popularlized it, not science. I'm honestly happy the label has served all the AAers. And of course it would, its a de facto Step 1. If you don't believe that people become powerless over things (loss of control), then you naturally wouldnt believe that you became powerless over drugs.
Now addiction is real. But do all addicts lose control every time they use? Of course not. Even the hardest drinker could stop after drink number 1 if a gun was held to his head. There's no evidence to support the magical out of control theory.
