The Winnipeg Regional Health Authority has extended a warning after reporting that two adults were hospitalized with an illness allegedly caused by cocaine laced with a veterinary drug.

The Winnipeg Regional Health Authority claimed two adults were recently hospitalized diagnosed with a rare illness known as neutropenia that hampers the immune system, rendering them in a state in which they are unable to fight off infections. In severe cases, if left untreated, the disease can be fatal.

The WRHA quoted that Levamisole is a drug used by veterinarians to rid animals of internal parasites, but is not used in humans. However, is able to cite the reason as to why it might have been added to the cocaine.

Also it is reported that it's not the first time neutropenia linked to tainted cocaine has engulfed Canada. There were 42 reported cases in Alberta and British Columbia between Jan. 2008 and March 2009, including one death.

"Even a dealer you trust may have tainted drugs and not know it", Plourde said in a statement. "Without medical treatment, the condition can lead to death".

Plourde reported that till date there were many cases of severe neutropenia in Alberta and British Columbia in 2008 and 2009 that were linked to levamisole-laced cocaine.
