References 12 through 31 were numbered incorrectly in the text and reference 11 was omitted in the list of references in the article entitled "Sexually Transmitted Diseases in a Health Maintenance Organization Teen Clinic: Associations of Race, Partner's Age, and Marijuana Use" published in the August issue of the ARCHIVES (1999;153:838-844). Subsequent references should have been numbered 11 through 30, not 12 through 31, in the text and in the list of references.
