This study is a secondary analysis of data gathered under the sponsorship of the Utah State Division of Alcoholism and Drugs in 1989. The researchers concluded that there is a difference in frequency of alcohol use, source of alcohol, and age of first alcohol use among LDS, Other Religions and No Religion subgroups. There is no significant difference found among the various religious subgroups for age of first marijuana use of quantity of alcohol use. For all religions except Jews, a lower percentage of Utahns used alcohol than their national counterparts. A theoretical model for LDS Drug use is presented.
