Different strokes for different folks, just because someone walks Path A to get to the goal doesn't mean that it's the only viable path. They may have replaced one addiction with another and if they have its a healthy addiction that doesn't cause harm to themselves or others. There is really no wrong way to get sober, finding what works for you is crucial and maintaining it is key. (Points taken away from some AA older timers, the good kind that don't say 'my way or the highway')
