This thesis examined relationships between alcohol and drug use in adolescents and if it contributed to the participation of a one-night stand. Other variables investigated include gender, condom use, and attendance in religious services. To be included in the current study the participant had to fall between the ages of 18-25 years at the time of data collection and to report they engaged in sexual intercourse at least once within the past year (N=570). There is a significant relationship between alcohol use and participation in one-night stands. This did not hold true for drug use. The rate of condom use decreased when participants reported to use alcohol. There were no significant relationships between condom use and drug use. Significant relationships were found between participating in one-night stands and attendance of religious activities. Further research needs to be conducted to see what the relationships between these variables among today's youth.
