Background: Studies of the association between substance use and condom use in specific sexual encounters often do not separate the effects of alcohol and different types of drugs. Because the pharmacological effects and social settings of various substances differ, their effects on unprotected intercourse may vary as well.
Goal: This study examined the relationship between alcohol and drug use and the use of condoms in sexual encounters with casual partners in a high-risk population of drug offenders.
Design: Participants in court-ordered drug diversion programs (n=536; 26% female) completed a questionnaire in which they reported on the circumstances of their most recent sexual encounter with a casual partner.
Results: In multivariate logistic models, alcohol use in conjunction with sex was not related to decreased condom use in either men or women. Amphetamines (smoked or injected) were associated with decreased condom use, while cocaine, marijuana, and orally-administered amphetamines were not significantly associated with condom use.
Conclusions: In this high-risk sample, links between substance use and unprotected sex differ with type of drug used.
