How has alcohol and the abuse of other drugs affected HIV’s infection and spread? Immensely, especially in regard to women. Most women who are known drug or alcohol users or are known recovering addicts have contracted HIV. Part of the problem stems from women who use intravenous drugs like heroin for their highs: a number of 46% has been attributed to women who are intravenous drug users. Another shocking figure comes in the form of women who are heterosexual but have had sexual contact with male intravenous drug uses. 18% of women become infected this way.
