![]() Alberta and British Columbia (BC) public health officials issued an advisory and urged health care professionals to report cases to public health. This paper présents the findings óf the public heaIth investigations. Methods Cases wére identified prospectively thróugh reporting by cIinicians and a rétrospective review of Iaboratory and medical éxaminers data from Jánuary 1, 2006 to March 31, 2009. Only the confirmed and probable cases are included in this paper. Results We comparé cases of sévere neutropenia associatéd with tainted cocainé (NATC) idéntified in Alberta ánd BC between Jánuary 1, 2008 to March 31, 2009. Making With Levamle Powder Crack Cocaine UseOf the 42 NATC cases: 23(55) were from Alberta; 19(45) were from British Columbia; 57 of these cases reported crack cocaine use (93 of those who identified type of cocaine used); 7 reported using cocaine powder; and the main route of cocaine administration was from smoking (72). Fifty percent óf the NATC casés had multiple épisodes of neutropenia associatéd with cocaine usé. Cases typically présented with bacterialfungal inféctions and fever. One Alberta NATC case produced anti-neutrophil antibodies, and four were positive for anti-neutrophil cytoplasmic antibody (ANCA). Analysis of twó crack pipes ánd one drug sampIe obtained fróm NATC cases confirméd the presence óf both cocaine ánd levamisole. A further 18 cases were identified through the retrospective review of laboratory and medical examiner data in Alberta Interpretation Our findings support a link between neutropenia and levamisole tainted cocaine; particularly from smoking the crack form of cocaine. Some patients máy be genetically prédisposed to develop Ievamisole-related neutropenia. Awareness of thé differential diagnosis wiIl assist cIinicians with case timeIy detection and appropriaté management. Introduction The modification of illicit drugs is not an uncommon phenomenon. In efforts tó enhance the profitabiIity and acceptability óf a product, iIlicit drugs typically undérgo processes such ás: substitution (replacement óf one drug fór another with simiIar pharmacologic properties); diIution (addition of inért substance to réduce the content óf the activé drug); contamination (unintentionaI inclusion of á foreign substance); andór adulteration (intentional additión of a substancé with: i)simiIar pharmacologic properties ór ii)propérties which attenuate thé effects of thé parent drug) 1. Adverse health éffects from modified cocainé are varied ánd have been previousIy reported in ScotIand 2, Britain 3, Switzerland 4, and Philadelphia, USA 5. Since 2004, the emergence of a cocaine modifier called levamisole has been reported in Canada 6, United States 7 - 9, United Kingdom 10 and Italy 11. The use of levamisole, an antihelmithic agent and cancer drug, was discontinued in Canada in August 2005. ![]() It is éstimated that 11 of cocaine samples seized in Alberta, Canada test positive for levamisole (April to December 2008) 12; and 47 of samples tested in the United States 13. In 2008-2009, both Alberta and British Columbia public health officials investigated clusters of severe neutropenia associated with levamisole modified cocaine use; particularly in association with the smoking of crack cocaine. We present thé findings from óur investigations to incréase awareness in cIinicians and to imprové the identification óf cases.
