title: Injection drug use among homeless adults with severe mental illness.
abstract: OBJECTIVE
  This study examined injection drug use among homeless men and women with severe mental illness in two sites.
  
  
  METHODS
  The data were drawn from related clinical trials conducted in Baltimore (101 men, 49 women) and Boston (85 men, 33 women).
  
  
  RESULTS
  The percentages of homeless men with a history of injection drug use were 26% in Baltimore and 16% in Boston; the corresponding rates among homeless women were 8% and 6%.
  
  
  CONCLUSIONS
  Taken together, these and previous results suggest high lifetime prevalences of injection drug use-and associated risks of HIV transmission-in this elusive population.
