Background Drug users are at high risk of acquiring HIV. Differences in sexual risk between NIDU and injection drug users (IDU) are not well understood.

Objective: To investigate differences in HIV risk between NIDU and IDU.

Methods People at high risk of acquiring HIV (n=823) were interviewed in Upstate New York (2001-2004). Use of 9 non-injection and 4 injection drugs, condom use during vaginal/anal intercourse and number of sexual partners in the past year were assessed. Drug use was categorized based on the number of drugs used and frequency of use (heavy/moderate/light).

Results 63.4% of participants used illicit drugs (60.0% NIDU, 24.4% IDU). Users took a mean of 2.3 non-injection and 2.0 injection drugs. 31.3% of NIDU were heavy users compared to 74.5% of IDU. Participants had substantial sexual risk: an average of 6.3 partners and 63.7% had unprotected intercourse.

Use of any drugs was associated with unprotected intercourse. People who only used non-injection drugs were more likely to have unprotected intercourse (p<0.001) and more partners (p=0.01) than IDU.

Use of more types of non-injection drugs predicted having unprotected intercourse (p=0.009) and more partners (p<0.001). Moderate (p=0.004) and heavy (p=0.007) NIDU had more partners than light users. The number and frequency of injection drugs used by IDU were not associated with sexual risk.

Conclusion IDU carries a direct and substantial HIV risk but may diminish sexual activity. Many non-injection drugs are taken to enhance sexual activity, contributing to high sexual risk. Health professionals should address NIDU when assessing HIV risk.
