Druglink factsheet 2012 – Heroin and Anthrax

Anthrax is a bacterium which creates spores that can infect the body, produce lethal poisons and lead to death. The infection among heroin users is most likely to be acquired through:
• spores entering the skin or tissues under the skin (such as fat or muscle), via injecting contaminated heroin into the body;
• breathing in spores while smoking or snorting contaminated heroin (inhalation).
