A guy who had been an alcoholic one day went into a church service had someone pray for him and from then on he quit drinking . . . just like that. So I believe that if you are religious or were religious and currently you are struggling to overcome an addiction then going to church and the support you'll get would help you fight the cravings and if you have faith in the 'higher power' then quite obviously you'll stay clean for as long as you attend church meetings.
