aim:  Acute intoxication where cocaine is present is one of the most common causes of death among homeless and unstably housed (HUH) women.  We determined whether factors disproportionately common in impoverished populations increase the risk of initiating stimulant use among HUH women living in an urban setting.

methods:  Between June 2008 and August 2010, biological women were systematically sampled from San Francisco homeless shelters, free meal programs and low-income hotels. The relative risk of stimulant use (crack cocaine, powder cocaine or methamphetamine) during the first six months of follow-up was estimated.

results: Among 260 women, the median age was 47, 70% were women of color and 47% reported having recent unmet subsistence needs.  Abstinence from stimulants at baseline was reported by 118 participants (53%). Adjusting for baseline sociodemographics and drug treatment, the risk of initiating stimulant use among women who did not use at baseline was significantly higher among those who reported recent sexual violence (Adjusted Relative Risk [ARR]= 4.31; 95% CI:1.97-9.45) and sleeping in a shelter or public place (ARR=2.75; 95% CI:1.15-6.57).

conclusion:  Almost half of HUH women used stimulants at baseline, and 14% of those who did not, initiated use within 6 months. Substance use treatment may have a significant impact, but by itself insufficiently addresses impoverished women’s vulnerability to factors that increase the risk of stimulant use such as sexual violence and homelessness. Addressing upstream risk factors by preventing homelessness and sexual violence is critical to reduce stimulant use among impoverished women.
