Abstract
Prevalence estimates of homosexuality among 225 drug-abusing clients in treatment were placed at 11%. The rate among Black cocaine free-basers was 17%, and among Black opiate users the rate was 10%. These rates are two to three times the rate of homosexuality among the general population. They may be an underestimation because of our inability to detect hidden homosexuality among those persons wishing to remain undetected in gender orientation.
