The disease model of addiction is still hotly debated in the USA. It has been widely discredited and thrown out in other western nations. What's the difference in these nations? These other nations have some form of socialized medicine so you don't have to have a medical illness to have your treatment costs covered. On the contrary, the only way to get treatment costs paid for addictive behaviours in the USA, by a medical insurance company, is if you have a disease. Try asking your medical insurance to pay to stop you making bad choices or changing your habits. The work of Stanton Peele is seminal in this field for anyone interested. Also check out The Freedom Model. Completely heretical to AA types but to rational thinkers struggling with an addictive behaviour, it could be life changing.
