Belief in God and drug use

TGGP asked about the relationship between belief in God and use of illicit drugs. Based on GSS data:

Percent who have used illegal drugs in the past year (sample size = 885)

Doesn't believe 13.6
No way to find out 9.5
Some higher power 4.7
Believes sometimes 6.7
Believes but doubts 1.8
Knows God exists 2.2
 
Compared to believers, atheists are six times as likely to have used drugs. (There are only 22 atheists in the sample, so the difference is not statistically significant. If we calculate the chi-square for the overall relationship between belief and drug use, it is statistically significant.)
