Not looking for an argument, just pointing out that people, often well meaning, inadvertently set up roadblock after roadblock for quitting. My last point about not quitting unless you are happy, for example, feeds right into the addiction, which is telling the addicted person that life without drugs will be hollow, meaningless, boring, etc. The tapestry of normal living is, of course, far more dynamic and richer than can be envisioned from within the bubble of addiction. Happiness is just one part of that tapestry, not the end-all, be-all, and certainly not a pre-requisite for living without getting high.
