text: Odd comment from someone with your experience. In over 30 years of working directly and indirectly with addicts, I saw no correlation between faith and sobriety. Those with good support systems (often family) and resources (money/access to services) did somewhat better, but even the most fortunate addicts were too often unable to overcome their addictions.
  
  If you actually worked in the field, I'm sure you observed that the vast majority of addicts are Christians - just like the general public - but they don't have higher recovery rates. Anecdotal evidence supports incorporating spirituality into recovery, but it's nuanced. To some, spirituality does not include a god.  Others may feel more comfortable when treatment resembles their faith - whatever it is.
  
  No reliable comparison data exists, primarily because programs present their data in a way most likely to get customers or support their perspective (http://www.recovery.org/topics/find-a-top-spiritual-and-faith-based-rehab-center/)
