Drug abuse is a serious problem, both globally and at a local level, with more than 13,400 opiate abusers in Dublin, Ireland, alone [1]. Infectious complications are responsible for 60-80% of hospital admissions of IV drug users [2]. In 2000, in the United Kingdom and Ireland, fatalities associated with soft-tissue inflammation and severe systemic sepsis were linked to "skin popping" (injection of drugs into the skin and subcutaneous tissues rather than directly into a vein). Clostridium species were implicated in the pathogenesis [3, 4]. Superficial infection may progress to more widespread local or distant disease. Primary soft-tissue infections in IV drug users include cellulitis, abscess, myositis, pyomyositis, and necrotizing fasciitis.
