Sugar, Spice, and Bleeding.

Brodifacoum (BDF), otherwise known as superwarfarin, is a long-acting anticoagulant rodenticide (LAAR) which acts as a vitamin K antagonist. Much like warfarin, BDF's mechanism of action is to irreversibly inhibit the enzyme vitamin K epoxide reductase, thus reducing the recycling of vitamin K and, therefore, reducing the activation of clotting factors two, seven, nine, and 10. Although BDF is usually found in rodenticides, it has been recently used as an additive in synthetic cannabinoids. We present a case of a young male with a history of synthetic cannabinoid use who presented with hematuria and epistaxis and was ultimately found to have BDF poisoning.
