Some scholars have suggested that individual religiosity inhibits deviant b
ehavior: Others have suggested that behavior is more responsive to the infl
uence of religiously-oriented moral communities than to the religiosity of
individuals. Still others have suggested that non-religious moral communiti
es, such as sports teams or self-help recovery groups, are just as effectiv
e as religious moral communities. The current article examines the associat
ions between addicts' reductions in drug and alcohol use and religiosity, i
ncrease in church attendance, and increase in addiction self-help recovery
group attendance, following participation irt publicly funded treatment pro
grams. Results indicate that increase in self-help recovery group attendanc
e and church attendance were independently associated with reduction in alc
ohol use. Only increase in church attendance was significantly associated w
ith reduction in cocaine use. Self-assessed religious conviction was not as
sociated with changes in drug use.
