The purpose of the study was to determine the pattern of drug types reported by enlisted personnel applying for amnesty under the Navys Drug Exemption Program as well as to attempt to differentiate on the basis of certain demographic and cognitive variables between a random sample of individuals receiving drug related discharges and those receiving honorable discharges during the three year period prior to the implementation of the Exemption Program. More than 86 percent of the Exemption applicants reported using a combination of drug types about 30 percent reported Opiate use, and about 5 percent were drug dependent. Drug users were younger, held lower pay grades, and had a lower educational level than those not reporting illicit drug use. The results of the discriminant analysis yielded a significant difference between the two groups on five of the cognitive variables but the resulting classification scheme left much to be desired in that one third of the time it favored misclassification of those who received drug related discharges and those who received favorable discharges.
