The disease model creates more of the very problems it allegedly solves. The best way to overcome addiction is to rely on your own willpower. People can stop relying on drugs or alcohol as they develop other ways to deal with life. Addiction has more to do with the environments people live in than with the drugs they are addicted to. People often outgrow drug and alcohol addiction.
Drug addiction is a way of life people rely on to cope with the world.
Those prophecies encourage people to recognise the will-power they have to control their life. As people come to believe they can develop other ways to deal with life instead of relying on drugs or alcohol, they gain confidence in their ability to determine their own destiny. As they come to believe addiction has more to do with the environments they live in than with the drugs they use, they may further realise they have the power to change those environments in order to help themselves. They may recognise they are the 'higher power'. And that, of course, is the most sacrilegious idea to disease modelists.
